PEAK READING. The highest toxic and combustible gas
levels and the lowest oxygen levels. Depressing the ON/OFF
button while in this mode clears peak values.
USER SETUP. User setup mode allows pump, voice and
confidence beep to be turned on or off as desired. It is also
here that calibration is usually done, and memory cleared (See
Section 4.7 Clearing Memory). To enter the user setup mode,
keep depressing the MODE button until line 3 of display
indicates “USER SETUP”. Press the ON/OFF button to enter
user setup mode, to bypass each setting depress the MODE
button. To change any setting, depress the ON/OFF button.
For example, to change pump, voice, or confidence beep from
“ON” to “OFF” or vice versa, depress the ON/OFF button when
the appropriate menu item is displayed. To enter calibration
mode, depress the ON/OFF button when “CALIBRATE?” is
displayed(SeeSection5Calibration).
4.3 TESTING SENSORS AND ALARMS
It is recommended that proper alarm function be verified prior
to use by applying calibration or alarm check gas. Alarm check
gas (Test 1A) should be used only for instruments that contain
one or more of the 4 standard sensors (O2, LEL, CO or H2S).
For other configurations, use calibration gas with instrument in
normal operating mode. After testing, remember to clear the
peak values, or if “ALARM TYPE” is set to “TWA ON”, clear
memory. Test low flow alarm by placing finger over inlet when
in pump mode. If instrument does not go into low flow alarm
when inlet is blocked, instrument should be operated in
diffusion mode after entering the “USER SETUP” mode and
changing the pump status configuration to “PUMP OFF”.
Instrument should be serviced as soon as possible to fix the
problem.
