Initiate Cal
Perform a calibration.
If you replaced a cell, or your cell has failed a regular calibration
because of a deterioration, you will need to perform a primary calibra-
tion rather than a regular calibration. See the
Primary Calibration
section in
Setup Key
Chapter 4 for help.
Ensure that all calibration gases flow into the analyzer at the same
flow rate. use the flow knob to regulate the flow of gases into the
analyzer.
If you have the pump option turned on when you start a calibration,
the system will automatically shut the pump off. After calibration you
will have to turn the pump on again and adjust the flow rate to 150
sccm (± 5 sccm).
1. Enter the calibration gas values to match the span and zero calibra-
tion gases you intend to use to calibrate your system (see the “Cal Gas
Values” section later in this chapter for help on how to do this). See
Chapter 3 for other calibration gas recommendations and cautions.
2. From the
Calibrate Key
menu, select
Initiate Cal
.
Have you entered
the Cal/Vrfy values?
3. Select
Continue Cal
if you have already entered the calibration values.
Select
Abort Calibration
to exit the calibration so you can then enter
the calibration values.
Continue Cal
Abort Calibration
You are then prompted to apply the O

span gas to the inlet port on
the sensor (tubing must be free of oil and dirt):
