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 Gas Tracer on as described in “Turning On the Gas Tracer, Leak
Check Mode” on page 96. Select the desired display range. In the example
below, 500 ppm has been selected.
2. Press and hold the RESET SILENCE button until the Peak Hold Mode screen
displays.
The current methane reading is displayed on the first line. The “PH” shown on
the second line indicates that the Gas Tracer is in Peak Hold Mode. The peak
methane reading is displayed on the third line. The full scale value is
displayed on the fourth line.
3. The peak reading displayed while in Leak Check Mode will appear in the
Peak Hold Mode screen.
4. If the highest reading recorded is higher than the full scale value, the full scale
value will be displayed. If the full scale value is changed to something higher,
the real value for the peak will be displayed. Even if CO DISP in Maintenance
Mode is turned on, the CO channel will not be displayed in Peak Hold Mode.
5. To reset the peak, press and hold the RESET SILENCE button until you hear a
beep, then release it.
6. To exit Peak Hold Mode and return to Leak Check Mode, press and hold the
RESET SILENCE button until you hear the Gas Tracer’s second beep and the
Leak Check Mode Screen displays.
