CAUTION:
If the internal Faradaic calibrator is used to condition the
Ultra Trace sensor, the calibrator must be refilled with
calibration electrolyte after 10 hours of operation (see
Chapter 3). Failure to refill the calibrator will result in a
CURRENT FAILURE error message. To refill the calibra-
tor with calibration electrolyte, return to the Analyze
mode. (From the Calibration mode, press ESC.) After
refilling the calibrator, replace the electrode assembly and
return to the Calibration mode.
To condition the Ultra Trace sensor, go to the Calibration mode and select
either the GAS or INTERNAL calibration mode (see Span Calibration on the
next page). Select MANUAL SETTLING. Stay in the Calibration mode (do
not press ACK in step 7 during conditioning with an external gas or step 10
during span calibration with internal calibrator). The output will increase slowly
with time, and will eventually reach a steady state value. This is a result of
electrolyte slowly wetting the catalyst in the sensing electrode. After the
catalyst has been completely wetted, the output will stabilize.
After conditioning, the signal output will reach at least one-third of the preset
span value. For example, a 9 PPM span gas used during conditioning will result
in output of at least 3 PPM after conditioning. Once the output has reached
of the span value, press ACK to adjust the analyzer span.
CAUTION:
Failure to condition the Ultra Trace sensor may result in a
"CELL TOO WEAK" error message. To correct this,
condition the sensor again and recalibrate the analyzer.
If the output after conditioning for a maximum period of
48 hours does not reach
sensor.
NOTE: It is recommended that the analyzer be spanned before the
background signal is offset.
