Remote Calibrate/Remote Verify
To initiate a remote calibration or verification, do the following:
1. Enter the calibration gas values to match the span and zero calibra-
tion gas cylinders you intend to use to calibrate/verify your system
(see the “Cal Gas Values” section later in this chapter for help on how
to do this). These values are referred to in this section as setpoint
values.
2. Select Initiate Cal or Initiate Verify from the Calibrate key menu,
depending on whether you want to perform a calibration or verifica-
tion.
3. Select Remote Calibrate or Remote Verif y.
The following then appears on your display (display line 2 will only
appear if you have the combustibles option):
O2 xx.x % Set xx.x %
Cmb y
Press ENTER to Span
4. Press the Enter key once the O
2
reading on the far left of the first
display line stabilizes. The reading on the far right of the first display
line shows the setpoint value you entered using the Cal Gas Values
menu option. This setpoint value should match the cal gas cylinder
value.
•
If your O
2
reading on the far left of the display has stabilized, yet is not
near the setpoint value on the far right of the display, you should check
the cal gas value you entered and ensure that this value matches the cal gas
cylinder for that gas in the RCU.
When performing a primary calibration or the first calibration after
a primary calibration, the reading and the setpoint values often
won’t match. Once the first regular calibration after a primary
calibration is performed, the readings should match.
