3.3.11 CAL Menu

The Model 187 is factory calibrated by AMI to match a specific sensor.
However, the Model 187 also provides a USER calibration function for
installations where a user may want to perform a calibration when all
sensor equipment is completely installed.

Typically, the user will not need to perform a USER calibration. AMI
recommends using the FACTORY calibration unless directed otherwise by
an Authorized AMI Technical Support Representative.

The CAL menu is accessed by pressing the

&$/

key. The CAL menu

first requires that the user enter the 4-digit calibration passcode recorded
in the first page of this manual. Key in the calibration passcode and press

asterisks (*) are displayed indicating entry of each digit as illustrated
below.

Note

All measurements are suspended once the CAL menu has been
entered (including the passcode entry screen). All measurements
restart when the CAL menu is exited.
