Calibration For P48
When re-calibration is required (generally every two years), this procedure
should be performed by qualified technicians using appropriate equipment.
Equipment source accuracy of 0.03% or better is required.
The procedure consists of applying accurate voltage and current signals.
Allow a 30 minute warm-up period before starting this procedure.
This procedure may be aborted by disconnecting power to the controller
before exiting the configuration mode. The existing calibration settings
remain in effect.

Main or Second Linear DC Analog Output Calibration
1. Set the Linear DC Output jumper for the range to be calibrated. (See Linear
DC Analog Output Jumper Selection, page 12).
2. Connect a meter with an accuracy of 0.05% or better to output.
3. For each step, use the controller arrow keys to adjust the external meter
display to match the parameter being calibrated. Press P when the output
is correct, or if the parameter is not being calibrated.
