again. Press A. The controller will then return to F. Press L to
return to the Display Loop. This will not overwrite any user settings but will
erase the controller calibration values. This procedure does not require any
calibration signals nor external meters. This can be used to clear calibration
error flag .
CAUTION: This procedure will result in up to ±10% reading error and the
controller will no longer be within factory specifications. For this reason, this
procedure should only be performed if meter error is outside of this range to
temporarily restore operation until the unit can be accurately calibrated.
For further technical assistance, contact technical support.

Analog Output Calibration (T16 and P16)
Set the controller Analog jumpers to the output type being calibrated.
Connect an external meter with an accuracy of 0.05% (or better) that is capable
of measuring 10.00 V or 20.00 mA to terminals 6 (+V/I) and 7 (-V/I). The
voltage or current calibration that is not being used must be skipped by pressing
A until End appears.
