PCA
5.0 CALIBRATION
Calibration
NOTE: Bacharach recommends that the PCA be calibrated
by your nearest Bacharach Service Center. Calibration,
however, can be performed in the field if your facility has the
necessary equipment and qualified personnel to perform the
procedures described in the sections that follow.
Important! To prevent the loss of data during calibration,
perform the following procedures using fresh batteries, or
using an optional Power Supply (see Section 3.2).
Do not make calibration adjustments to the instru-
ment without applying calibration span gas. Making
adjustments without applying span gas could render
the instrument inaccurate or unusable until re-cali-
bration is performed correctly with span gas.
5.1 Sensor Check
Important! Before turning on the analyzer or performing
any of the calibration procedures, ensure that the analyzer
will be sampling fresh air, and that the probe is at room
temperature.
When the analyzer is first turned on and allowed to cycle through its
60 second warmup period, and while sampling fresh air, the sensors are
checked (read) and calibrated (set) to the following ambient conditions:
•
Oxygen sensor is spanned to 20.9%
•
Carbon Monoxide sensor (if installed) is zeroed
•
Nitric Oxide sensor (if installed) is zeroed
•
Pressure sensor (if installed) is zeroed
If a sensor problem is detected by the analyzer’s microprocessor during
the warm-up cycle, an error message will be displayed at the bottom of
the LCD display. Refer to Section 7.2 for a listing of the error codes.
