e. Date and Time
f. Gas Type (indicating type of calibration gas)
g. Serial Number
h. Cal Due (up coming) or Cal Past Due
i. Sensor Warm Up and Please Wait
j. Autozero (all gases and pressure sensor)
k. Auto Bump Test (optional)
l. Working display showing all gases sensed and battery
power remaining
2. If the display fails to illuminate or BAT LOW is shown on the
display, replace the batteries.
3. If any sensor is past the intended calibration cycle, CAL PAST
DUE will appear during the start-up sequence. The instrument
will also show which sensor is due for calibration at that time.
During “Autozero” all sensors will be displayed with the zeroing
result (passed or failed). Pressing and holding any button will
freeze the display screen during warm-up to allow extended view-
ing.
4. If after the warm-up period, the instrument determines that
a sensor is inoperable, an ERROR message will flash for
that sensor. Then FAIL will show on the display for the corre-
sponding sensor. Attempt to manually zero using
SAVE/ZERO BUTTON(C).
5. The display will indicate the type of gas used for calibration
or to be sensed and the unit of measure (i.e.: LEL, PPM, %
VOL) below all readings.
See page 37 for optional configurations for the combustible gas
