ü The sniffer line SL3000XL is optionally connected to the rear side of the device, see
Device setup [}14]".
ü Possible alternatives to the operating possibilities on the device are set up
(optional):
I/O-Modul or Bus-Modul, see “Accessories [}101]“.
1
Switch on the leak detector via the power supply switch.
ð After start-up, the device is ready for operation; no special start procedure for
measuring is required.
2
Make sure that the correct basic settings and the settings for the current
measurement are carried out, see “Basic settings [}34]“ and “Settings for the
measurements [}55]“.
3
Make sure that calibration takes place daily.
ð When performing a calibration, note the 20 minute warm-up time, see
“Calibrating the device [}60]“.
4
To measure, hold the sniffer tip close to the possible leak or run it along a weld,
for example.
ð The tip must touch the test object.
ð If the detection limit has deteriorated, you can detect leaks at a greater
distance (high flow) from the suspected leak and switch to low flow using the
right button of the sniffer handle for more accurate location.
5
Track the measurement result either as a line or as a bar graph, see
“Touchscreen elements [}20]".
6
To measure small leak rates more clearly, use the ZERO function. To switch on,
press the ZERO button on the sniffer handle for a longer period (> 5 s), see also
Operating elements on the handle [}19]“.
ð To activate ZERO on the sniffer probe, it must be activated in the menu, see
also Suppressing gas backgrounds with "ZERO" functions [}67]“.
ð If ZERO is switched on, you will see the text ZERO with white background in
the measurement window.
7
Record the measured values if necessary, see "Recording data [}71]" and
"Copying measurement data, deleting measurement data [}72]".
8
Switch the instrument off.
