FUNCTION
DESCRIPTION
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. The G3 model
has a range of gases that can be selected via an internal gas
table.
SENSITIVITY
The GasCheck G has three sensitivity levels:
• X100 (times one hundred) — the most sensitive
• X10 (times ten) — mid range
• X1 (times one) — least sensitive
BATTERY STATUS
When the battery symbol is filled in, the battery is full. When
the battery symbol is outlined, the battery is exhausted.
BACKLIGHT
INDICATOR
The backlight symbol shows the status of the backlight, even
in bright daylight.
GAS
MEASUREMENT
The GasCheck G2 and G2 measure the leak rate of gas
leakage in whichever units are selected.
SOUND
INDICATOR
The symbol shows if the sounder is on or off. If the semicircle
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 it relies on this bar graph to
indicate leakage. When gas is detected and the bar graph
has reached its maximum level, a different sensitivity level
can be selected to give a wider detection range.
PEAK HOLD
INDICATOR
When selected, peak hold displays the maximum
measurement on the display. Pressing the ENTER key resets
the reading but also logs the peak reading in memory.
