Overscale Conditions
If the gas level goes over the display range, the gas reading will be replaced with “OVER”
and the LEDs and buzzer will pulse continuously until the overscale condition has cleared.
Once the gas level gets low enough, the instrument will start showing ppm readings again.
Peak Hold Mode
Peak Hold Mode allows the user to view the peak methane reading for the operating
session while viewing the current methane reading.
To enter Peak Hold Mode:
1.
Turn the GX-6000 on as described in “Turning On the GX-6000, Leak Check Mode”
on page 165. Select the desired display range. In the example below, 5000 ppm has
been selected.
2.
Press and release the RESET button. The Peak Hold Mode screen displays. The
current methane reading is displayed on the first line. The peak methane reading is
displayed on the second line. The display range is displayed on the third line.
3.
If the highest reading recorded is higher than the display range value, “OVER” will
be displayed instead of a gas reading. If the display range value is changed to
something higher, the real value for the peak will be displayed.
4.
To exit Peak Hold Mode and return to Leak Check Mode, press and release the
RESET button.
