About the SDM-2012
The SDM-2012 Docking Station is an advanced, reliable system that provides
charging, calibration, bump testing, and calibration and bump test records for both the
GX-2012 and GX-2012GT portable gas monitors. It is designed to save thecalibration and bump test records to a USB flash drive (standalone functionality) or
to be connected directly to a computer (PC controlled functionality). If calibration andbump test records are stored to a USB flash drive while operating in the standalone
configuration, the Single Module Data Viewer Program can then be used with aWindows-based personal computer to retrieve calibration and bump test data files
from the USB flash drive or from the computer’s hard drive if the files have beentransferred to the hard drive from the flash drive. If you are using the PC Controller
Program while operating in the PC controlled configuration, you may retrieve
instrument data, bump test, and calibrate up to 10 instruments at once. Instrument
information and data for each instrument can be viewed directly using the PC
Controller Program and can be printed from the PC Controller Program. For
instructions to use the SDM-2012 with the PC Controller Program, see the SDM-2012
Docking Station PC Controlled Configuration Operator’s Manual.

Chapter 3: Preparing to Use the SDM-2012
Overview
There are four tasks that must be completed before you can begin to use theSDM-2012: hardware assembly, setting or confirming the bump test and calibration
parameters, connecting calibration gas, and installing the Single Module Data Viewer
Software on your computer. This chapter describes how to assemble the parts thatare shipped with the SDM-2012, how to set or view the bump test and calibration
parameters, and how to install the Single Module Data Viewer Software on a
Windows based personal computer.

Hardware Assembly
The hardware assembly consists of connecting the AC adapter, installing the air filter,and connecting the sample tubing. Perform the following to complete the hardware
assembly:
1. Place the SDM-2012 on a convenient table top near an AC wall socket in awell ventilated area. A location near a window that can be opened is best sothat the exhaust can be routed to the window.
2.

Connect the AC adapter’s wall plug into a wall AC socket.

3.

Insert the round plug on the end of the AC adapter’s cable into the power jackon the back of the SDM-2012.

NOTE:

4.

If you have multiple SDM-2012s and are using a 3-port AC adapter,plug each of the round plugs on the end of the AC adapter into thepower jack on the back of 3 separate SDM-2012s.
Install the exhaust line, a clear 12 inch long tube with a black plastic push-on
fitting, by pushing the open end of the exhaust tube onto the exhaust line
connection fitting located in the upper left corner of the instrument panel. You
may then push the black push on fitting of the exhaust line onto the exhaustline storage fitting on the other side of the instrument panel.

Install the air filter so that the arrow on the filter that indicates direction of flow
is pointing towards the AIR fitting. Push the open end of the flexible tube that ison one end of the filter onto the AIR fitting on the back of the SDM-2012.

6.

Install the 10 foot long 5/16 inch ID flexible tube that is included with the SDM2012 onto the exhaust fitting located in the upper left corner of the back panel.
Route the tube to an area where the exhaust can be safely dispersed, such as
an open window.

CAUTION:

7.

The maximum recommended length for the exhaust tube is 10 feet. Do
not use more than 10 feet of tubing or tubing with an ID of less than
5/16 inch for the exhaust tube or the bump test and calibration
accuracy may be adversely affected. The tube that is shipped with theSDM-2012 has an ID of 5/16 inch and is 10 feet long.

Install the 3 foot long 3/16 inch ID tubes that are included with the SDM-2012
on the GAS 1 and GAS 2 fittings.

15 • Hardware AssemblySetting the Operational Parametersin Edit Mode
Once the hardware has been assembled, use Edit Mode to confirm or adjust thebump test and calibration parameters, the H2S gas inlet parameter (GX-2012 only),
and the WET/DRY setting (GX-2012GT only) before using the SDM-2012.
The bump test parameters define how long fresh air and calibration gas are applied to
an instrument during a bump test. They also define the tolerance used in determining
whether an instrument fails or passes a bump test and whether or not a calibration
automatically takes place if a bump test fails. The calibration parameters define howlong fresh air and calibration gas are applied to an instrument during a calibration.
The H2S gas inlet parameter defines what gas inlet fitting (GAS 1 or GAS 2) will be
used for H2S during bump tests and calibrations. This setting applies to GX-2012s
only since GX-2012GTs do no have H2S sensors installed. The WET/DRY setting
defines the type of gas that will be used for the fresh air adjustment and for calibration
gas during the bump testing and calibrating of the ppm combustible gas sensor. Thissetting applies only to GX-2012GTs.
The bump test and calibration parameters are saved in the SDM-2012’s memory. If aparameter is changed with one particular instrument installed in the SDM-2012, thechange will be in effect for the bump test or calibration of any subsequent instruments
until the parameter is changed again.

Bump Test & Calibration Parameters
There are four bump test parameters and two calibration parameters. The two
calibration parameters, air sample time and calibration gas sample time, are also
bump test parameters. The parameters are described below. Table 3 below shows
the factory settings for the bump test and calibration parameters. If you wish to use
the factory settings, then you do not need to make any parameter adjustments. If you
wish to confirm or change the parameter settings, follow the instructions below in“Setting the Bump Test Parameters” on page 21 or “Setting the Calibration
Parameters” on page 23.

Air Sample Time (AIR)The air sample time can be set separately for bump testing and calibration. It is thelength of time that the SDM-2012 will draw air through the AIR fitting on the back of
the docking station. Air is drawn during a bump test or calibration before an air adjust
operation and to purge calibration gas from the system after calibration gas has beendrawn through the GAS 1 or GAS 2 fittings on the back of the docking station.
Calibration Gas Sample Time (GAS)The calibration gas sample time can be set separately for bump testing andcalibration. It is the length of time that the SDM-2012 will draw calibration gas throughthe GAS 1 or GAS 2 fittings on the back of the docking station during a bump test or
calibration.
Bump Test Check Tolerance (CHE)
The bump test check tolerance only applies to bump testing. It determines how close
the instrument gas reading must be to the calibration gas concentration for eachchannel during a bump test in order to pass the bump test. It is defined as apercentage of the calibration gas concentration.The amount that the instrument gas
reading differs from the calibration gas concentration must be equal to or less than
this percentage of the calibration gas concentration. For example, if the tolerance is
set to 50%, and the %LEL calibration gas concentration is 50% LEL, then the bump
test gas reading for the LEL channel on the instrument must be 50 %LEL ± 25 %LEL.
Automatic Calibration (CAL)
Automatic calibration only applies to bump testing. It can be set to on or off. If it is set
to on, then the docking station will automatically perform a calibration if a bump test
fails.
NOTE:

If the Bump Test Function in the instrument is turned ON, theinstrument’s Setup Mode setting for AUTO CAL takes precedence overthis setting in the SDM-2012. If the SDM-2012’s CAL setting is set to
OFF but the instrument’s AUTO CAL setting is set to ON, a calibration
will still automatically be started after a failed bump test.

17 • Setting the Operational Parameters in Edit Mode

Turning on the SDM-2012 with an Instrument
Do the following to turn on the SDM-2012 and establish a connection with an
instrument:
1. Confirm that the AC Adapter is connected to the SDM-2012 and to an AC wall
socket.
2.

Press and hold the SDM-2012’s POWER button. The LEDs will turn amber.

3.

When the BUMP T and CAL .A LEDs turn off, release the POWER button.

4.

The COPY LED will be steadily on or off and the CHARGE LED will be blinking
green if the SDM-2012 is operating properly or solid red if there is a system
failure. The amount of free memory in the SDM-2012 will dictate the conditionof the COPY LED (see “Available Memory in the SDM-2012” on page 92).

5.

Install an instrument in the appropriate recess of the instrument cradle. The
plastic flap should be covering the recess not in use. Flip the plastic flap over if
it is covering the recess you need to use.

NOTE:

If you are only charging an instrument or viewing or editing parameters,
you do not need to connect the gas out to instrument line or theexhaust line to the instrument.

Updating the Tested Sensors Setting
The tested sensors setting allows the user to control what sensors are tested during abump test or calibration that is performed using the SDM-2012. If Std is selected, only
the standard sensors will be tested during a bump test or calibration performed using
the SDM-2012. For a GX-2012, only the LEL/O2/CO/H2S channels will be tested. For
a GX-2012GT, only the LEL/O2/CO channels will be tested. If ALL is selected, every
sensor in the instrument will be tested during a bump test or calibration performed
using the SDM-2012. This will include the %volume sensor for a GX-2012 or GX2012GT and the ppm combustible sensor for a GX-2012GT.
NOTE:

Even if the tested sensors setting is set to Std, all additional sensors(ppm combustible and %volume) can still be tested using the
instrument’s Calibration Mode.

Connecting Calibration Gas
The GAS 1 and GAS 2 fittings on the back of the docking station are designed to be
used with a calibration gas cylinder that is fitted with a demand flow regulator. The
AIR fitting may be used with a demand flow regulator and a cylinder of zero
emissions air, but this is not normally necessary since the docking station will
generally be in a fresh air area. If you are using the SDM-2012 with a GX-2012GT
and a zero air cylinder is used, the zero air calibration cylinder must be connected to
the AIR fitting using a 6 inch humidifier tube.
The type of calibration gas cylinder used depends on the gas sensors installed in the
instrument being used with the calibration station. Typically a 4-gas mix will be used if
the instrument being used with the calibration station is a 4-gas GX-2012. If a 5sensor GX-2012 is being used, a 100% volume methane cylinder will also be needed.
If a GX-2012GT is being used, a 1000 ppm methane cylinder and a 3-gas cylinder
are needed. If a GX-2012GT with a %volume sensor is being used, a 1000 ppm
methane cylinder, a 3-gas cylinder, and a 100% volume methane cylinder are
needed. The 1000 ppm methane cylinder should be connected to the GAS 2 fitting
first using a 6 inch humidifier tube. The docking station will begin every bump test or
calibration with the ppm sensor. The user will need to change the GAS 2 cylinder tothe 100% volume methane cylinder (if %volume sensor installed) when prompted to
do so by the PC Controller Program during bump testing and calibration.
Use Table 4 below as a guide in determining which and how many calibration gas
cylinders are appropriate for your system.
NOTE:

Do not use a 4-gas cylinder or any cylinder that includes H2S whenbump testing or calibrating a GX-2012GT. H2S adversely affects
the ppm combustible sensor.

To connect calibration gas to the SDM-2012, do the following:
1.

NOTE:

If the area around the docking station is not considered a fresh air area (anarea free of combustible and toxic gases and of normal oxygen content,
20.9%) install a tube not longer than 10 feet on the filter attached to the AIR
fitting on the back of the docking station and route it to a fresh air area orconnect a cylinder of zero air with a demand flow regulator to the AIR fitting.
If you will be using a zero air cylinder with a GX-2012GT in thedocking station, you must connect the zero air cylinder to the AIR
fitting using a 6 inch humidifier.

2.

Install the demand flow regulator on the calibration gas cylinder(s).

3.

Connect the demand flow regulator to the GAS 1 or GAS 2 inlet fitting using
the 3 foot length of 3/16 inch ID sample tubing provided with the docking
station.
For a 3- or 4-gas mix, connect the regulator to the GAS 1 inlet.
For a special calibration cylinder (ppm or %volume), connect the regulator to
the GAS 2 inlet keeping in mind that you will need to use a humidifier if bumptesting or calibrating a GX-2012GT.

Chapter 4: Operation
Overview
When you have completed the tasks in "Chapter 3: Preparing to Use the SDM-2012",
you are ready to use the SDM-2012 docking station. The SDM-2012 is capable ofperforming bump tests and calibrations on the GX-2012 and the GX-2012GT. It canalso charge the optional rechargeable lithium ion battery pack in the instrument. This
chapter describes procedures for using the docking station to bump test, calibrate,
and recharge instruments in the standalone configuration of the docking station. It
also describes the information that is saved in the docking station’s memory and how
to save that information to a USB flash drive for use with the Single Module Data
Viewer Program.

Bump Testing a GX-2012
The following instructions apply to GX-2012s with one or more of the standard four
sensors (catalytic LEL, O2, CO, and H2S). They also apply to GX-2012s with a%volume combustible sensor. See “Bump Testing a GX-2012GT” on page 57 for
instructions to bump test a GX-2012GT.
When a bump test is performed, the SDM-2012 performs a fresh air adjustment on a
GX-2012 and then applies calibration gas to the instrument. The docking station thenanalyzes the response results based on criteria defined by the bump test checktolerance parameter and determines if the instrument passed the bump test. The
bump test check tolerance is defined in “Bump Test Check Tolerance (CHE)” on
page 17. If the automatic calibration parameter is set to ON, then the SDM-2012 willautomatically perform a calibration if the bump test fails.
Do the following to perform a bump test on a GX-2012:
1.

Confirm that the AC Adapter is connected to the SDM-2012 and to an AC wall
socket.

2.

Press and hold the SDM-2012’s POWER button. The LEDs will turn amber.

3.

When the BUMP T and CAL .A LEDs turn off, release the POWER button.

4.

The COPY LED will be off or on steadily and the CHARGE LED will be blinking
green if the SDM-2012 is operating properly or solid red if there is a system
failure. The amount of free memory in the SDM-2012 will dictate the conditionof the COPY LED (see “Available Memory in the SDM-2012” on page 92).

5.

Install a GX-2012 in the instrument cradle. The plastic flap should be covering
the recess not in use. Flip the plastic flap over if it is covering the recess youneed to use.

6.

Connect the gas out to instrument line to the inlet fitting on the GX-2012.

Bump Testing a GX-2012GT
The following instructions apply to standard GX-2012GTs that contain the standard
sensors (catalytic LEL, ppm combustible, O2, and CO). They also apply to GX2012GTs that have a %volume combustible gas sensor installed. See “Bump Testinga GX-2012” on page 35 for instructions to bump test a GX-2012.
When a bump test is performed, the SDM-2012 performs a fresh air adjustment on a
GX-2012GT and then applies calibration gas to the instrument. The docking station
then analyzes the response results based on criteria defined by the bump test checktolerance parameter and determines if the instrument passed the bump test. The
bump test check tolerance is defined in “Bump Test Check Tolerance (CHE)” on
page 17. If the automatic calibration parameter is set to ON, then the SDM-2012 willautomatically perform a calibration if the bump test fails.
The SDM-2012 will bump test the ppm sensor using the GX-2012GT’s WET setting
for both the fresh air adjustment and the gas application. If the SDM-2012 is not in a
fresh air environment, a zero air cylinder must be used with a 6 inch humidifier tube
connecting the cylinder to the AIR fitting. Another 6 inch humidifier tub must always
be used to connect the ppm calibration cylinder to the GAS 2 fitting. See the GX2012GT Operator’s Manual for a description of the instrument’s DRY and WET
settings for bump testing and calibration.
NOTE:

The SDM-2012 performs a complete bump test on the ppm
combustible sensor first. Be sure that the 1000 ppm methane
calibration cylinder is connected to the GAS 2 fitting on the back of theSDM-2012.

To perform a bump test on a GX-2012GT:
1.

Confirm that the AC Adapter is connected to the SDM-2012 and to an AC wall
socket.

2.

Press and hold the SDM-2012’s POWER button. The LEDs will turn amber.

3.

When the BUMP T and CAL .A LEDs turn off, release the POWER button.

4.

The COPY LED will be off or on steadily and the CHARGE LED will be blinking
green if the SDM-2012 is operating properly or solid red if there is a system
failure. The amount of free memory in the SDM-2012 will dictate the conditionof the COPY LED (see “Available Memory in the SDM-2012” on page 92).

74 • Calibrating a GX-2012GT

Calibrating a GX-2012GT
The following instructions apply to standard GX-2012GTs that contain the standard
sensors (catalytic LEL, ppm combustible, O2, and CO). They also apply to GX2012GTs that have a %volume combustible gas sensor installed. See “Calibrating a
GX-2012” on page 48 for instructions to calibrate a GX-2012.
When a calibration is performed, the docking station performs a fresh air adjustment
on an instrument and then applies calibration gas to the instrument. The docking
station analyzes the calibration results and determines if the instrument passed thecalibration.
The SDM-2012 will calibrate the ppm sensor using the GX-2012GT’s WET setting
for both the fresh air adjustment and the gas application. If the SDM-2012 is not in a
fresh air environment, a zero air cylinder must be used with a 6 inch humidifier tube
connecting the cylinder to the AIR fitting. Another 6 inch humidifier tub must always
be used to connect the ppm calibration cylinder to the GAS 2 fitting. See the GX2012GT Operator’s Manual for a description of the DRY and WET settings for bumptesting and calibration.
NOTE:

The SDM-2012 performs a complete calibration on the ppm
combustible sensor first. Be sure that the 1000 ppm methane
calibration cylinder is connected to the GAS 2 fitting on the back of theSDM-2012.

To perform a calibration on a GX-2012GT:
1.

Confirm that the AC Adapter is connected to the SDM-2012 and to an AC wall
socket.

2.

Press and hold the SDM-2012’s POWER button. The LEDs will turn amber.

3.

When the BUMP T and CAL .A LEDs turn off, release the POWER button.

4.

The COPY LED will be off or on steadily and the CHARGE LED will be blinking
green if the SDM-2012 is operating properly or solid red if there is a system
failure. The amount of free memory in the SDM-2012 will dictate the conditionof the COPY LED (see “Available Memory in the SDM-2012” on page 92).

5.

Install a GX-2012GT into the instrument cradle. The plastic flap should becovering the recess not in use. Flip the plastic flap over if it is covering therecess you need to use.

TroubleshootingCharging an Instrument in a Docking Station
The SDM-2012 can be used to charge the rechargeable Li-ion battery pack in an
instrument equipped with it. To maximize the instrument’s run time and the battery
life, make sure the battery pack’s charge is as low as possible before recharging it.

Recharging a Battery Pack After Performing a Bump Test
or Calibration
1.

Perform a bump test or calibration on an instrument as described in “Bump
Testing a GX-2012” on page 35, “Calibrating a GX-2012” on page 48, “Bump
Testing a GX-2012GT” on page 57, or “Calibrating a GX-2012GT” on page75.

2.

After the bump test or calibration has been completed, turn off the instrument
by pressing and holding the EDIT ENTER and POWER buttons
simultaneously until the instrument turns off, about one second, and thenreleasing them. The docking station will automatically turn off the instrument
15 seconds after a successful bump test or calibration or if no buttons arepressed for 10 minutes.

3.

Be sure that the AC adapter is plugged into a wall outlet, that the power jack is
plugged into the back panel of the SDM-2012, and that the instrument isproperly installed in the front recess of the instrument cradle.

4.

While the instrument is on, the CHARGE LED will be blinking green. When the
instrument is turned off, the CHARGE LED will blink amber. The BUMP T and/or CAL .A LED will continue to be either green or red depending on the resultof the previous bump test or calibration.

NOTE:

5.

The SDM-2012 does not start charging the batteries until the
instrument is off. While the instrument is on, the CHARGE LED will
blink green. Once the instrument is shut off, the CHARGE LED will
begin to blink amber.
If the battery pack is fully charged, then the CHARGE LED will turn solid green
in a few minutes.
If the battery pack is drained enough for the docking station to charge it, theCHARGE LED will continue to blink amber while charging is taking place. The
SDM-2012 will take approximately 4 hours to charge a fully discharged battery
pack.
If the charging process encounters a fail condition, the CHARGE LED will turnsteadily red.

6.

When the charge is complete, the CHARGE status LED will turn solid green.

It will not connect to the docking station. The instrument cannot be bump tested orcalibrated in the charge cycle. Once the 5 minute charge cycle has ended, the unit
will automatically turn back on and connect to the docking station. The unit can now
be bump tested or calibrated.

Calibration and Bump Test Records
The SDM-2012 saves a record of each bump test and calibration performed. It iscapable of saving up to 200 such records. When an SDM-2012’s memory becomes
full, the oldest record is overwritten when a new record is saved. The records savedin the SDM-2012’s memory can be saved to a USB flash drive using the USB port on
the front.

Available Memory in the SDM-2012
The COPY LED indicates how much of the SDM-2012’s memory has been used. The
table below describes the various indications.
Table 6: COPY LED Indications
COPY LED Indication

Solid Amber

More than 80% of the SDM-2012’s memory
has been used.

Solid Red

The docking station’s memory is full. A
newly saved record will overwrite the oldest
one.

Copying Calibration and Bump Test Records to a USB Flash Drive
The SDM-2012 will only perform a copy operation if there is at least one record saved
in its memory. If there are no records saved in the docking station’s memory, the
COPY LED will be off and the COPY button will not function. Do the following to copy
calibration and bump test records in the SDM-2012’s memory to a USB flash drive.

Calibration and Bump Test Records • 92

NOTE:The USB port on the front of the docking station cannot be used toconnect the SDM-2012 to a computer, only to save calibration andbump test records to a USB flash drive.

1.

Confirm that the AC Adapter is connected to the SDM-2012 and to an AC wall
socket.

2.

Press and hold the SDM-2012’s POWER button. The LEDs will turn amber.

3.

When the BUMP T and CAL .A LEDs turn off, release the POWER button.

4.

The COPY LED will be off or on steadily and the CHARGE LED will be blinking
green.The amount of free memory in the SDM-2012 will dictate the conditionof the COPY LED (see "Available Memory in the SDM-2012" above).

5.

Install a USB flash drive into the USB port on the front of the SDM-2012. The
SDM-2012 will take a few seconds to determine how much memory isavailable in the flash drive.
•

If the flash drive’s available memory is not enough for the contents of theSDM-2012’s memory, the COPY LED will alternate between green and red.
Enough memory will have to be cleared in the flash drive to make room forthe records in the SDM-2012’s memory.

•

If there is enough available memory in the flash drive for the contents of theSDM-2012’s memory, the COPY LED will begin flashing in the same colorthat it was before installing the flash drive.

6.

Press and hold the COPY button until the COPY LED turns red, then release
it. The COPY LED will become solid red while the records in the docking
station’s memory are copied to the flash drive. In addition, if the flash drive has
an LED, it will begin to blink.

7.

When the COPY LED returns to its original color and begins blinking again andthe flash drive’s LED (if it has one) stops blinking, the copy operation iscomplete. Remove the flash drive from the USB port.

NOTE:

8.

If you pull out the flash drive while its LED is still blinking or the COPY
LED is still solid red, the file saved in the flash drive with the calibration
and bump test records may be incomplete.
If the flash drive has not already been used with a docking station, a folder
named DAT will be created on the flash drive and a file with all the saved
calibration and bump test records will be saved to this folder.
If the flash drive has been used before with a docking station, the file will besaved to the existing DAT folder.

9.

The files on the flash drive can now be either transferred to a computer or kept
on the flash drive for use with the Single Module Data Viewer Software. See

93 • Calibration and Bump Test Records

"Bump Test and Calibration Record Files" below for a discussion of these files
and how to use them.

Clearing the SDM-2012’s Memory
Make sure that you save the bump test and calibration records in the SDM-2012’s
memory to a flash drive before clearing its memory. The docking station’s memory
can be cleared by simultaneously pressing and holding the CAL .A and COPY
buttons for five seconds. After the SDM-2012’s memory has been cleared, the COPY
LED will turn off indicating there are no records to be copied.

Bump Test and Calibration Record Files
Each time a copy function is performed, a file is saved to the flash drive in the DAT
folder. The file name will begin with “SDM-2012” and the remainder of the file namewill depend on the serial number of the SDM-2012 used and the date of the mostrecent bump test or calibration performed on the SDM-2012. So it is possible to havemultiple files in the DAT folder from the SDM-2012.
The files that an SDM-2012 saves to a USB flash drive are structured so that they canbe imported into a database controlled by the Single Module Data Viewer Software.
See “Importing Files Into the Database” on page 97 for instructions to add files to the
database.

Bump Testing or Calibrating and Saving Files To a Flash Drive
Multiple Times In One Day
The SDM-2012 assigns file names to calibration and bump test record files based on
the day of the most recent calibration or bump test record saved in the docking
station’s memory. If bump tests or calibrations are performed, a copy operation is
performed, then additional bump tests or calibrations are performed, and anothercopy operation is performed with the same flash drive all on the same day, theexisting file on the flash drive from the first copy operation will be overwritten by thefile from the second copy operation because its name will be the same as the new
file. In this case, no information is lost since the second file saved to the flash drive
includes all the records that were in the first file.
However, if bump tests or calibrations are performed, a copy operation is performed,
and the SDM-2012’s memory is cleared, then additional bump tests or calibrations
are performed, and another copy operation is performed with the same flash drive allon the same day, this will result in the information in the file from the first copy
operation being lost. This is because the file saved to the flash drive in the second
copy operation only includes records since the memory was cleared and when it
overwrites the file from the first copy operation, all the information in the first file is
lost.
CAUTION:If performing bump tests or calibrations and copying an SDM-2012’s
memory to a flash drive multiple times during the same day and theSDM-2012’s memory is cleared, transfer the calibration/bump test
record files from the flash drive to a computer hard drive or some othermemory device before performing another copy operation to avoid lossof data.
