9. At the prompt, input a time interval (in hours) at which an automatic COe
calibration will occur and press ENTER.
To disable automatic calibration for O
2
and COe, enter 0 for both CalIntrvl
parameters.
6.3 Operator-initiated autocalibration
An operator can initiate an automatic calibration at any time, as long as the
transmitter is equipped with calibration solenoids.
6.3.1 Autocalibrate using the optional local operator
interface (LOI)
To initiate a calibration using the LOI, perform the following steps on the LOI
menu tree. Refer to Figure 4-4 for the LOI menu tree.
Procedure
