Use of the sniffer tip extension

technical handbook

For the purpose of measuring refrigerant concentrations (e.g. in the case of alreadypackaged test objects in the package), for reaching points which are difficult toaccess or for finding large leaks quickly a flexible extension (Cat. No. 511-020) may
be screwed onto the filter holder (see Fig. Fig. 1-3/5). Make sure that the plastic hosesurrounds holder and filter holder. The 400 mm long extension (Fig. 1-3/6) may bepulled out after pressing down the ring of the holder (Fig. 1-3/8); if required, you cancut the extension down to the required length. The tip facing the test object must
always be cut at an angle of approximately 45°.

1.5.7.4

Use of water protection tip
In order to avoid sucking in liquids, the water protection tip (Fig. 1-3/7) (Cat. No. 511025) may be screwed onto the filter holder. The water protection tip will prevent
liquids in up to about 3 mm in height (the e.g. puddles of condensed water) frombeing sucked.

Fig. 1-4 Water protection tip fitted

kina40e 01.fm(1307)In order to prevent the entry of liquids when working on moist test objects, the handle
should not be held vertically with the sniffer tip facing up, this avoids liquids in thewater protection tip from flowing back into the sensor. If, even so, liquid has been
sucked into the sensor system, let the HLD5000 run for about 10 minutes (not in thestandby mode) to pump out the liquid from the sensor system via the supply pump in
the main unit.

Principle of Operation

2.1

Description
The HLD5000 is capable of detecting, measuring and displaying quantitatively therefrigerant or C02 sucked in through the probe’s line by means of its infrared gas
analyzer.

technical handbook

2

The important subassemblies of the HLD5000 are:•the sensor system subassembly located in the probe•

the pump system together with the electric and electronic subassemblies
accommodated in the main unit

Infrared light from a corresponding source is made to pass through a cell throughwhich also the gas taken in by the HLD5000 flows. This light is filtered so that only
light having a specific wavelength is allowed to pass on to an infrared light detector.
If in the presence of a leak, refrigerant or CO2 enters with the air taken into the cell,
the infrared light is partly absorbed by the refrigerant. The intensity of the lightarriving at the detector is thus reduced.

(1307)

The change in the intensity of the light is amplified electronically, converted fromanalogue to digital and is displayed visually and audibly after processing by the
microprocessor in the main unit. By means of a reference measurement based on
the ambient air, the background concentration of the test gas or other interferinggases is taken into account when processing the measured data.

CautionThe HLD5000 will only operate after having connected the sniffer line first.

Caution
Do not place the HLD5000 on hot surfaces.

NoticeIn the default setting the serial numbers of the main unit and the probe has
to match.

Press the mains switch (Fig. 3-1/6) to switch on the HLD5000. The HLD5000 will takeabout 30 seconds to warm up as indicated by the display.

CautionDuring warm-up the sniffer tip must not be inserted in the test leak opening.
Otherwise, the internal calibration will be disabled and an error message will be
displayed.

After the warm-up phase of the HLD5000, an audible signal is produced and the leakdetector will be ready to make measurements. The green LED (Fig. 3-3/2) in theprobe indicates that the HLD5000 is ready to make measurements. The type of gas
to which the HLD5000 has been programmed as well as the unit of measurement for
the leak rate (factory default: g/a) is indicated on the display (Fig. 3-1/4). Moreover,
the type of probe (detectable gas) to which the HLD5000 has been set up is indicatedon the sticker on the probe.

technical handbook

3.2

Working with the HLD5000
Provided the HLD5000 has been adapted to the specific requirements of theapplication (see Chapter 4) and calibrated accordingly, a leak test can be performed
as follows:
Lead the probe tip as close as possible to the locations that are to be tested. Ifneeded, the tip may even touch the unit under test.

Warning
Danger of electric shock.
•

Do not touch live parts with the sniffer tip.

•

Test samples need to be disconnected from electricity before leak testing.

Caution
Under all circumstances the intake of liquids which may still be present on thesurface of the test object has to be avoided.
In the case of moist test objects (e.g. condensed water) the use of the water
protection tip is recommended (see Chapter 1.5.7).
If a welded seam or a joint needs to be tested, the tip of the probe should be moved
no faster than 2.5 cm/s (1 inch/s) across the location which is to be tested. The
distance between probe tip and unit under test should be kept as small as possible.
In the case of probing a specific location, the tip should remain in place briefly (atleast 1 s).

(1307)The HLD5000 compares the measured leak rates with the rejection leak rates(trigger levels) set up as described in Chapter 4.1. If the measured leak rate exceeds
the rejection leak rate, then more than half of the yellow lamps (LED) on the arcshaped display (Fig. 3-1/5) will come on and an audible alarm is released.
Due to its working principle (see Chapter 2.1) background concentrations in theenvironment are suppressed and do not cause an alarm. Refrigerant clouds in frontof large leaks will also be considered a background concentration. Different from thebehavior of its predecessor HLD4000, the HLD5000 will not alarm when only
approaching leaks from a larger distance. Larger leaks will also only be detected
when close to the leak and thus, can be localized reliably.

kina40e 03.fm

NoticeIf you can not guarantee getting close enough to the leak (as describedabove) larger leaks may be missed. In this case, please use the flexible
sniffer tip extension (Cat. no. 511-020) which is delivered with the
HLD5000. For this application the extension tip can be cut down to 100 mm(4 in.) length for easier handling. (see Chapter 1.5.7.3)

Depending on the measurement mode (see Chapter 4.1) the test should be repeatedwith the key of the probe pressed to precisely pinpoint the location of the leak or to
double check the rejection leak rate.

Menu Item STANDBY
Pressing the standby key makes the HLD5000 enter the standby mode during which
the valve in the handle is disabled and the diaphragm pump is shut down.
In this mode, no leak rate measurements can be run.
When letting the HLD5000 enter the standby mode by operating the key "Standby”
and not through the automatic shut down feature (can be configured through themenu item "AUTO STANDBY”) during the first 25 seconds, the HLD5000 can only bereactivated by pressing any key.
After this time, operating any key on the HLD5000 or moving the handle will reset theleak detector back to the measurement mode.

4.4

Selecting the gas typeFor selective, single gas probes (Cat. No. 510-010, 510-015, and 510-018 or sniffer
line Cat. No. 511-010, 511-015, and 511-018) the detected gas type can be changed
by connecting a different, selective sniffer line.
For the SMART probe the detectable gas can be selected from a list of 5 preprogrammed gases plus three user-definable gases. (See „Gas Type“ in Chapter
4.1.1)

4.5

Calibration

kina40e 04.fm(1307)The HLD5000 is equipped with a built-in calibrated leak by means of which the leakdetector may be calibrated. The service life of the calibrated leak is about 2 years.
Three months before expiration of the calibrated leak a message will be displayed
reminding the operator to replace it.
NoticeThe SF6 and CO2 version of the HLD5000 is not equipped with its own
calibrated leak. Calibration will only be possible using an external
calibrated leak (see „Gas Type“ in Chapter 4.1.1).

NoticeWhen operating the SMART probe user definable gases will require to becalibrated with an external test leak until a calibration factor is entered forthis gas type.

NoticeReplacement leaks should not be purchased in advance of their need asthey have a limited lifetime. Any leaks being held in stock should be kept ina cool place.

NoticeIn order to ensure accurate measurements wait for at least five minutes
after switching on before running a calibration.

Checking the Calibration
A calibration can be checked by inserting the probe tip into the calibration port
without depressing the button on the probe. A message will be displayed indicating
whether or not the calibration is still OK (refer also to Chapter 4.1.4, manual
calibration).
On the leak rate display, two LEDs to the left and right of the 100% mark will flash. If
the measured value is outside this mark, a recalibration will be required. The
currently measured value is indicated by two moving LEDs just like during thecalibration process. Moreover, the calibration status is indicated on the display.

technical handbook

4.5.1

A recalibration can be started immediately by pressing the button, and the probe tip
does not have to be removed from the calibration port.
If a recalibration is required, this is indicated on the display and by an audible tone.
During the check, the probe must be held still and straight.

4.5.2

Calibrating the HLD5000 with the COOL-CheckTo calibrate the HLD5000, press the button on the probe and insert the sniffer tip into
the calibration port at the front of the main unit. The HLD5000 will then start thecalibration process automatically. During the calibration process it is not necessary
to keep the button on the probe pressed. The individual phases of the calibration
process are indicated on the display which also informs the user about a successful
calibration.
During the calibration process, the probe must be held still and straight,
otherwise no calibration will be possible.

NoticeDuring the calibration, the opening for the calibrated leak should not be
exposed to strong air flows (from air-conditioning units, for example).

NoticeWhen performing the calibration using the extension tip Cat. No. 511-020
the insert should be used in the opening of the calibrated leak so as toensure that the tip is properly centered in the opening.

Messages

technical handbook

While operating in the leak detection mode, the display will provide information which
will support the operator using the HLD5000. Besides messages relating to leakdetector settings also warnings and error messages may be displayed.
The HLD5000 is equipped with comprehensive self-diagnostic means. If a fault
condition is detected by the controller board this is indicated via the display to theoperator.
Errors are events which force an interruption to the measurement sequence andwhich the HLD5000 is not capable of remedying on its own. Errors are displayed inplain text on the display. The error sound is a two-tone sound.
The error message can be erased by pressing the "OK” key.
As long as an error status exists, a warning triangle comes up in the lower line of thedisplay.

6.2.1.1

Exchanging the filters in the sniffer line

If the function “Request for filter replacement“ is enabled, the message „Please
replace filter holder!“ will be displayed every 40 hours of operation. After replacing
the filter holder and acknowledging the message the internal counter for this function
will be reset and the message will pop up after another 40 hours of operation. Any
dirty or clogged filter in the sniffer line will lead to the same error message as a dirty
tip filter holder. In dirty conditions the error message “flow at measuring line too low”
or “flow at reference line too low” may occur before expiration of these time limits. On
occurrence of these error messages please exchange the tip filter holder first. If thisdoes not fix the problem, please also exchange the filter cartridge.

technical handbook

We recommend to exchange the filter holder at the probe tip preventatively at least
once a week and the filter cartridge at the bottom of the sniffer tip at least once amonth.

The fine filters at the probe tip are firmly built into the filter holder. To replace the filter
holder please:

1 Unscrew the filter holder from the probe tip
2 Screw on a new filter holder.
Replacement filter holders are available for order in sets of 20 pieces asCat. No. 511-027.
The fine filters at the bottom of the sniffer tip are firmly built into the filter cartridge.
