Then show

After a short while the LCD display will then revert to the display format previously set up for the leak rate,
which can be either the bar graph or the digital display, the latter in normal or large numeric display format.
When not detecting leaking gas, Gas Check still flashes and bleeps periodically to indicate that it is ON. Gas
Check remembers the settings on instrument power off so that the operator rarely if ever has to alter any of
them. The settings for gas groups, range, audio bleep, peak hold and nozzle are shown on the LCD.
The response of Gas Check can readily be checked against an Ion Science CalCheck. Alternatively the
tracer gas supply can be suitably fitted with an Ion Science Ltd Standard Calibrated Leak.
Recommended leak search procedure
General procedure
Note: When you use the Gas Check, do not allow dirt or debris to enter the end of the probe or nozzle. If the
probe or nozzle is blocked, the Gas Check will not operate correctly.
The following test procedures assume that you have fitted the short probe. The response time of the Gas
Check increases from about 1 second or less when the short probe is fitted to about 9 seconds when the
long probe is fitted. If you use the long probe for leak detection, ensure that you move the end of the probe
much more slowly along the area you leak test.
Ensure the unit under test contains a reasonable percentage of a trace gas that is different from normal air!
