Gas selection
The GasCheck G2 and G3 display the gas being measured in the top left of the running screen. The GasCheck G2 will
display the gas selected at the factory only however the G3 model has a range of gases that can be selected via an
internal gas table.
Sensitivity
GasCheck G has three (3) sensitivity levels, X100 (times one hundred) is most sensitive, X10 (times ten) is mid range and
X1 (times one) is least sensitive. See the sensitivity of various gases on the table under 'Functions (continues), Gas
Selection'.
Battery status
When the battery symbol is filled in the battery is full, when just an outline the battery is exhausted
Backlight
The backlight symbol shows the status of the backlight even in bright daylight.
Gas measurement
The GasCheck G2 and G3 measure the leak rate of gas leakage in which ever units are selected.
Sound indication
This symbol shows if the sounder is on or off, if the semi circle (on the right) of the symbol is present then the sound is
switched on, if not the sounder is switched off. The beep that occurs with each key press can not be switched off.
Bar graph
The bar graph increases as gas is detected. This graph is not scaled and should be used for indication only.
The GasCheck G1 has no measured units so relies on this bar graph to indicate leakage, when gas is detected and the
bar graph has reached it's maximum level, a different sensitivity level can be selected to give a wider detection range.
Peak hold
When selected, peak hold displays the maximum measurement on the display. Press the ENTER key resets the reading
but also logs the peak reading in memory.
