The controller is fully calibrated from the factory. Recalibration is
recommended every two 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 F. In this 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.
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 1I 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.
RTD Resistance (T16)
RTD calibration requires a precision 277.0 ohm resistor with an accuracy of
0.1 Ω (or better). Connect a jumper between terminals 9 and 10 with a 0 ohm
jumper between 9 and 8 at 1 and the 277.0 ohm resistor between 9 and 8 at
2
. If using thermocouple only, the RTD calibration need not be performed.
Input Calibration (P16)
Process calibration requires a precision signal source with an accuracy of
0.03% (or better) that is capable of generating 10.0 V connected to terminals 8
(COMM) and 9 (+10V) and 20.00 mA connected to terminals 8 (COMM) and
10 (20mA). The current calibration can be skipped by pressing A at the not
applicable prompts if using the controller for process voltage only.

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.
