Wet Measurement:
The display for measurements using wet analysis are identical as for dry. The
water content in the flue gas will have to be determined and entered for reading accuracy. Refer to
Setup Menu.
3.3 RECALIBRATE
When the Firetron 1000 is first switched on, it automatically performs a zero calibration. A zero cali-
bration may be initiated manually by selecting recalibrate at the main menu. The ABORT function
key allows early termination of the zero cal cycle
(Note: Aborting the recalibration cycle may
cause
incorrect gas readings).
The completion or abortion (defaults to previous calibration) of a
zero calibration cycle records the voltage outputs of the cells as exposed to fresh air. The cell zero
values are displayed under: DIAGNOSTICS -> CELL ZEROS, or may be printed out using the
DIAGNOSTICS -> REPORT facility.
NOTE: Cell zeros are normally 0.0v (offset should be less than ±20mV), except for: O
2
(span
value) which should be around 1.6V TO 2.0V. Refer to section 3.5.2 diagnostic cell zeros.
