CALIBRATION
4;-'
The controller is fully calibrated from the
factory. Recalibration is recommended every two
<H
years by qualified technicians using appropriate
equipment. Calibration may be performed by
using the front panel or with the TP16KIT. The front panel
method is explained below. (Refer to the TP16KIT bulletin for
calibration instructions using TP16KIT cable and software.)
Calibration may be aborted by disconnecting power to the
controller before exiting Factory Service Module
case, the existing calibration settings remain in effect.
Note: Allow the controller to warm up for 30 minutes minimum
and follow the manufacturer's warm-up recommendations for
the calibration source or measuring device.
Millivolt Calibration (T16)
Millivolt calibration requires a precision voltage source with an
accuracy of 0.03% (or better) connected to terminals 8 (comm.)
and 9 (+). When calibrating the input, the millivolt calibration must
be performed first, then the Cold Junction or RTD Resistance.

Cold Junction (T16)
Cold Junction calibration requires a thermocouple of known
accuracy of types T, E, J, K, C or N (connected to terminals 8 and
9) and a calibrated external reference thermocouple probe
measuring in °C with resolution to tenths. The two probes should
be brought in contact with each other or in some way held at the
same temperature. They should be shielded from air movement
and allowed sufficient time to equalize in temperature. (As an
alternative, the T16 thermocouple may be placed in a calibration
bath of known temperature.) If performing the millivolt calibration
prior, verify that the correct input type is configured in Input
Module 0.1( before performing the following procedure. (After
the millivolt calibration the controller will default to type J.) If using
RTD only, the cold junction calibration need not be performed.
