2. Introduction

Page 4AD-4405A Weighing Indicator3. Installation and Precautions
3.1. Installation and Precautions
The AD-4405A weighing indicator is a precision electronic instrument. Handle it carefully.
The operating temperature is -10°C to +40°C (14°F to 104°F).
Do not install the scale in direct sunlight.
Mis-operation or other problems may be caused by an unstable power source including
momentary power failure or instantaneous noise. Use a stable power source.
Do not connect the power cord before the installation has been completed. Do nothandle the power cord with wet hands.
Verify that the local voltage and receptacle type are correct for your indicator.
Use shielded cables for all connections. Connect the cable shields to the shieldterminal or case as an earth terminal.
Earth ground the indicator. Do not share the earth ground line with other electrical
power equipment. There is an earth ground terminal at the power cord receptacle.
Do not install the indicator in a place where it is apt to be charged with static
electricity, or where the relative humidity is lower than 45%RH. Plastic and insulating
materials are apt to be charged with static electricity.
Even if the display is turned off, the power is on while the power cord is connected to the
AC power source.

3.2. Load Cell Connections
Connect the load cell wires to the connector (receptacle) located on the rear panel,using the accessory load cell plug.
It is possible to connect a 4 wire cable provided that pins 1-2 and pins 3-4 areconnected, if the distance between the indicator and the load cell is shorter than 5m.
At this time, use a cable with a wire having a cross-sectional area of 0.5 mm2 orgreater because thin cables will decrease the temperature coefficient.
The output voltage of a load cell is a very sensitive signal. Space the load cell cableaway from any noise source.
It is possible to connect four 350ohm load cells.
The load cell drive is 5VDC 5% between EXC+ and EXC-, the maximum current 60mA.

Standard connection

Connection available fora cable shorter than 5m.

(Recommended
wire cross- sectional
area: 0.5 mm2 or greater)

3. Installation and Precautions

3.3. Adjustment of the Load Cell Output
CautionWhen adding a resistor to adjust a load cell output, use a metal film
resistor in the range of 50kohm to 500kohm with a good temperature
coefficient. Use as large of a resistance value as possible in the range
in which the zero adjustment is possible. Solder this resistor at a point
near the load cell or the indicator.

In Case of Reducing the Output Voltage
When the zero output is too large, add a resistor
between EXC+ and SIG-.

In Case of Adding an Offset Voltage to the Output
When the zero output is too small, add a resistor
between EXC+ and SIG+.

3.4. Verifying Load Cell Output and Input Sensitivity
The input sensitivity of the indicator is 0.15V /division or more. Satisfy the following
inequality, when you design a weighing instrument using the indicator and loadcell(s).
CautionA change in input voltage sensitivity is required to cause a one divisionchange of the display. Select as large an input sensitivity voltage as
possible so that the weighing interval becomes stable.
Consider the leverage if a lever is used.

This indicator, converts an input voltage from a load cell to the "mass" value, anddisplays it. Calibration is the adjustment function so that the scale (indicator) can
display the weight correctly.

5.1. Items of Calibration Mode
There are four items in the calibration mode.
How to enter the calibration mode:
In the weighing mode, press the CAL key which is located behind the sealing panel.
Cal in is displayed for 2 seconds and then Cal 0 will appear. Use the MODE key toselect an item and use the ENTER key to execute it.
NOTE: Calibration could be started by simultaneously pressing the ZERO and TARE
keys, instead of the CAL key. The procedure is prohibited when the indicator
has received a certified approval.
Items Required to be Performed
Cal5et
Sets capacity, resolution, decimal point position and display format,
weighing range and unit. These items should be set first in order for theindicator to function as a weighing instrument. Set values do not need to
be changed again unless the indicator itself is replaced. For details, refer
to “5.2.1. Configuring a Weighing Instrument”.
Cal 0
Calibrates zero and span. This is required after installation, to get accurate
data. For details, refer to “5.2.3. Zero Calibration” and “5.2.4. Span
Calibration”.
Optional Items to be Performed as Necessarylnr 0
Performs digital linearization. Refer to “5.4. Digital Linearization
Function”.
g 5etCompensates for acceleration of gravity. Refer to “5.5. Gravity
Compensation Function”.
Gravity compensation function: Compensates for weighing error
between the calibration location and another weighing location using
gravity acceleration.
In the calibration mode, the keys have functions as follows:

When a value is mistakenly set, press the ESC key while holding the
ON/OFF key to finish the calibration mode without storing the value. After
CanCel is displayed, press the ON/OFF key to exit from the calibration modeand turns the display off.
NOTE:

Caloff can be displayed by pressing the +/- key while pressing the ON/OFF key,instead of CAL key.

CautionThe maximum display is less than or equal to 40000 divisions. This number
is calculated from the maximum capacity divided by the minimum division.
Check the accuracy of the weighing instrument periodically.
Recommended mass, use a mass heavier than 2/3 maximum capacity.
Calibrate the scale, if it is moved to another location or the environment
has changed.
It is not necessary to set the gravity acceleration correction, when calibrating
the scale with a calibration mass at the place where the scale is used.
Enter the stable weighing data while the STABLE mark is displayed. If
unstable data is used, it may cause a weighing error. Arrange thecondition using the F00 filter function.
The span calibration needs the zero calibration data. We recommendthat you perform the span calibration immediately after the zero
calibration.
If you use the dual range function of the multi-interval scale, perform the"Range Function", "Zero Calibration" and "Span Calibration".

5.3. Weighing Range Function

5.3.1.

Setting the Division and Range

Consider the following rules to design the weighing range.
Rule 1 Select the division and range of each weighing range so as to satisfy the following
inequality.
The first range < the second range
The division of the next weighing range is automatically set larger than the divisionof the lower weighing range. Changing the division is possible.
Rule 2 When setting the dual range, the upper limit value of the second range becomesthe maximum capacity.
Rule 3 Select a resolution smaller than 40000. The resolution is a value that divides the
maximum capacity by the minimum division of the first range.

5.4. Digital Linearization Function
Even if the zero and span calibration have been completed, there may still remain alinearity deviation caused by the performance of the weighing unit. The digital
linearization function can rectify or reduce the linearity deviation using weighing points
except zero and capacity. Up to three weighing points can be specified.
CautionThis function does not improve repeatability or hysteresis.
Use the mass on the condition that lnr 1 < lnr 2 < lnr 3.
Do not press the ENTER key while the STABLE mark is off.

Step 1 When Cal 0 is displayed, press the MODE key to display lnr 0 .
Step 2 Enter the zero point. Refer to “5.2.3. Zero Calibration”.
Step 3 The value of the middle point is displayed after indicating lnr x. x is 1, 2 or 3.
The triangle
mark of the same number(x) is displayed along with the value.
Step 4 Select a middle point.
If you want to cancel the current procedure, press the ESC key to finish thisfunction. Proceed to step 7 and other points are cleared (canceled).
Select a middle point value using the 0 - 9 keys. Proceed to step 5.
Step 5 Place a mass equivalent to the displayed value on the weighing unit. Wait for the
STABLE mark to turn on and press the ENTER key. Proceed to step 6.
Step 6 If you include a 2nd and 3rd middle point, repeat steps 3, 4, 5 for each point.
If you finish this function, proceed to step 7.
Step 7 Perform step 11 of "5.2.4. Span Calibration" immediately.

5.4. Digital Linearization Function

Page 18

AD-4405A Weighing Indicator5.5. Gravity Compensation Function
If the scale is used at the calibration location, it is not necessary to perform this function.
If there is a difference of gravity acceleration between the installed location andcalibration location it may cause a weighing error. This function specifies thegravity accelerations and corrects the span error.
Note

The decimal point is not displayed in the function. Example: 9798 = 9.798 m/s2
When span calibration is executed, the gravity acceleration correction will
be cleared and the two gravity acceleration values will return to the factory
settings.

Step 1 At the Cal 0 display, press the MODE key twice, g 5et is displayed and press the
ENTER key to enter the gravity compensation function.
If you want to cancel the current procedure, press and hold the ON/OFF key and press
the ESC key. Then, no parameters are changed and the calibration mode is finished.
Press the ON/OFF key to turn the display off after displaying CanCel.
Step 2 The parameter is displayed with triangle 1. Enter the gravity acceleration of thecalibration location using the 0 - 9 keys. The parameter xxxx is the gravity
acceleration.
ENTER key .. The key to store the new gravity acceleration and proceed to step 3.
ESC key....... The key to return to g 5et without changing the value.

Step 3 The parameter is displayed with triangle 2. Enter the gravity acceleration of theinstalled location using the 0 - 9 keys. The parameter xxxx is the gravity acceleration.
ENTER key .. The key to store the new gravity acceleration and proceed to step 4.
ESC key....... The key to return to step 2 without changing the value.

Step 4 Now g xxxx is displayed. Press the CAL key to store the parameters. Caloff isdisplayed. Proceed to step 5.
Caloff can be displayed by pressing the +/- key while pressing the ON/OFF key,instead of the CAL key.
Step 5 Press the ON/OFF key to turn the display off.

Description
In multi-interval scale. The last division is set to maximum ( d-50 ).
Therefore the next division can not be entered.
Resolution exceeds 40000. (Resolution = maximum capacity/ minimum
division)
Reduce the maximum capacity or increase the minimum division.
Load cell output is too large or too small at zero calibration. Check the weighing
unit and load cell. Refer to "3.4. Verifying Load Cell Output and Input
Sensitivity".
The calibration mass value exceeded the maximum capacity. Use thecalibration mass less than the maximum capacity.
The selected calibration mass is smaller than the minimum division.
The new input sensitivity is less than 0.15 µV/division. Increase the input
sensitivity. Refer to "3.4. Verifying Load Cell Output and Input Sensitivity".
When a mass is placed on the weighing unit, the load cell output becomes anegative value. Check the load cell cable connections and the direction of loadcell mounting.
The load cell output exceeds the input range before the maximum capacity.
Adjust zero balance referring to "3.4. Verifying Load Cell Output and Input
Sensitivity". Replace with a load cell designed for a smaller output. Or reducethe maximum capacity.
The weight value is out of the input range at zero calibration or spancalibration. Check the weighing unit and cables.

This function has the "upper / lower comparison", the "5-stage (HiHi / Hi / OK / Lo /LoLo) comparison", the "setpoint comparison" and the "simple batch". They compare
the weight data with preset parameters and can output the result of the comparison to
the display and buzzer, also to the relay-outputs of OP-03, OP-05 and OP-08.
Set the F-functions f22 and f23 to use the "upper / lower comparison", the "5-stage(HiHi / Hi / OK / Lo / LoLo) comparison" (these two comparison methods will be
combined and hereafter be called the "Weight check mode"), and f22 through f26 to
use the "setpoint comparison" and the "simple batch".
Data is stored in non-volatile memory and is not lost even if power is turned off.
Code memory can be selected by key switch, external control input, or a command
via the serial interface. Refer to “16.3. Command Format”.

10.1.

Weight Check Mode

This function compares the weight data with the upper and lower limit values (upper/lower
limit comparison) or four limit values of HiHi, Hi, Lo and LoLo (5-stage comparison), anddisplays, sounds the buzzer and outputs the results to the three relays of HI, OK and LO.
Use this comparison when judging whether a weight is proper.
Set the F-function f22 to 1, 2 or 3 to use upper/ lower limit comparison and f22 to 4, 5
or 6 to use 5-stage comparison.
Select a parameter of the F-function f23 for the comparison condition.
Set the F-function f26 (zero band) if f23 is set to 10 (not to compare in the zero band).
Specify the upper and lower limit / HiHi, Hi, Lo, LoLo limit values.
When entering the limit value(s), it is not necessary to enter the F-function f22 andf23 again unless comparison conditions are changed.
There are 3 type of setting values for each comparison.
(1) Set the limit value (upper and lower limit / HiHi, Hi, Lo, LoLo limit).
(2) Set the Target value and an acceptable tolerance (upper and lower) in weight.
The limit value is calculated automatically.
(3) Set the Target value and an acceptable tolerance (upper and lower) inpercentage of the target weight. The limit value is calculated automatically.
Example. Target = 50 kg, Upper limit = 51 kg, Lower limit = 48 kg(1) Hi (Upper limit): 51 (kg), Lo (Lower limit): 48 (kg)(2) TG (Target): 50 (kg), Hi (Upper acceptable tolerance): 1 (kg),Lo (Lower acceptable tolerance): 2 (kg) not a negative value(3) TG (Target): 50 (kg), Hi (Upper acceptable tolerance): 2 (% of Target), Lo(Lower acceptable tolerance): 4 (% of Target) not a negative value

AD-4405A Weighing Indicator11. Hold Function
This function displays the hold weight data after averaging the weight data for a
specific period.
Useful to determine a living animal’s weight.
Averaging time can be set up to 9.9 seconds by a 0.1 second step.
3 methods are available to start averaging; manual start, start automatically after
stable and manual / automatic start.
Manual start is available with key switch or external input.
Serial interface commands are also available; averaging start, releasing the hold dataand outputting the hold state. Refer to “16.3.4. Commands for the Hold Function”.
CautionThis function can not be used with Cf00=1.
Averaging can not start at a displayed value smaller than +/- 5 digits.
OVER data is not included for averaging.
When powered off, the hold is released automatically.
No peak hold function.

The Display and the Data Output of Hold and Average
The weight display blinks during the averaging period.
The output data in the averaging period is the actual weight at the time.
The weighing unit blinks when the weight display is in the hold state.
The output data format of the hold weight data is the same as that of the normal
weight data except the header of stable state is “HD” in the response to the “RW”
or “RW,n”(n=1 or 2) command.
Relations to the Other Functions
If automatic accumulation (f20=21) and/or auto print (f37=2, 3 f40=2, 3) is set,accumulation and/or data output is performed after the hold data is obtained.

This function determines the number of objects in a sample based on the unit
weight. The unit weight is stored in one of the code memory data in non-volatilememory, and is not lost even if power is turned off.

12.1.

Using the Counting Function

Preparation: Set f07 to 1 in the F-Functions.
Select a code memory number. Refer to “9.1. Using Code Memory”.
Register the unit weight. Refer to “12.2. Unit Weight Registration”.
Press the MODE key to enter the counting mode. The unit in the display changes to
pcs.
In the counting mode, TARE, ZERO, NET/GROSS and other operations are the sameas that in the normal weighing mode.

12.2.

Unit Weight Registration

There are three methods to register the unit weight. By weighing the actual samples todetermine the unit weight, by digital input of the unit weight, or by command via theserial interface.
The unit weight is one item of the code memory data. Select the code memory
number and start the unit weight registration in the weight display or piece countdisplay. The unit weight registration can not be done from the code memory
number display.
There is no counting accuracy improvement function by re-calculating the unit
weight based on the actual weight.

UFC Commands

UFC (Universal Flexi Coms) function enables editing the serial data output format
or the print output format freely using the serial interface command.
For customizing the print out of the printer or efficient data collection.
Output data is not only the indicator’s data/status but also characters at will.
It can output the control code* of the printer. (* depends on the individual printer)
There are 2 sets of memories for storing the parameters.
UFC Command Parameters
UFC commands such as SF1, PF1 have many parameters.
One command line can have multiple parameters. The parameters are stored inmemory in order.
Multiple UFC commands are acceptable. Parameters are stored next to the lastparameter stored by the last UFC command.

20. Current Loop Output (OP-08)

Current Loop Output
The current loop output can be used to output data to an A&D printer and a display
unit.
The current loop output is of the passive type and requires an external current sourceof 20 mA current. A&D’s printer and display unit can be connected without external
power source, because they supply the current.
The output terminals do not have a polarity. Each output terminal can be connected toeither the plus or minus inputs of the peripheral unit.
Set f36, f37, f38 and f39 of F-Functions. Please note the initial setting of f37 isdisabling the current loop output.
Data Format
The data format is the same as that of the initial setting of f34 of RS-232C data format.
The current loop output data format is fixed and can not be changed.
Header 2 and the unit selection are common to RS-232C (Cf06, Cf07).
Decimal point (dot or comma) and delimitter (comma or semicolon) can be set by f46.
