USING THE GASCHECK G SERIES
WARNING:
Before switching on the GasCheck, ensure the ambient air
is clean. The instrument automatically Zeros the sensor at
switch on. After the instrument has run through the start
up routine, adjust the instrument settings to the desired
levels. Check the instruments sensitivity using a CalCheck
or calibration kit.
1. Switch the GasCheck on by pressing the ON/OFF key. After the instru-
ment has completed its Zero routine, it will show its normal running
screen.
Ensure the instrument is on the X100 (times one hundred) range.
While on the main running screen, use the UP and DOWN key to adjust
between sensitivity ranges. X100 is the most sensitive, X1 is the least
sensitive.
2. Gas leaks tend to occur at pneumatic joints or welded seams. To
test for a leak, hold the GasCheck at a 45-degree angle to the object
being tested and drag the probe along the seam or joint at a rate of
approximately 25mm per second.
3. When a leak is detected, the bar graph will start to fill and the
frequency of the audio output will increase but will reduce as the
probe moves away from the leak. Return the probe to the suspected
leaking area and move slowly along the same area until the leak is
located. Once located, the probe should be held at the leak until the
numeric reading stabilizes.
4. The bar graph offers a graphical indication only and should not be
used to measure a leak. You many find that the numeric reading will
continue to increases after the graph has completely filled. Should the
instrument detect a leak that is too large for the range selected, the
numerical screen will flash and display “9999”. Use the UP or DOWN
keys to adjust the instrument sensitivity.
