• Calibration

General

The UTC/R is factory calibrated, you can change any setup options

without recalibrating.

During calibration allow a few seconds for signals to stabilise before

accepting the value.

Note: The millivolt source must be connected directly to the input

terminals using copper wire. Remove the CJC board first.

Equipment requirements

•

A suitable, stable millivolt source (accurate to 0.05 mV)

Terminal connections for input calibration

Calibration Stage Signal type Terminal

Input circuit

millivolt source + 2

millivolt source − 3

Input calibration procedure

When the

CIPy

Calibrate inputs? Start No

Connect the current source to the inputs (for connections see over page).

E=0

Set the millivolt source to 0.00 mV (and wait a few seconds) Calibrate Skip

E=8

Set the millivolt source to 8.00 mV (and wait a few seconds) Calibrate Skip

E=15

Set the millivolt source to 15.00 mV (and wait a few seconds) Calibrate Skip

E=30

Set the millivolt source to 30.00 mV (and wait a few seconds) Calibrate Skip

E=60

Set the millivolt source to 60.00 mV (and wait a few seconds) Calibrate Skip

AL=Y

Continue with the setup sequence.

Note 1: To discard changes to calibration and setup you can remove the power at this point.

Note 2: If the display shows OPEn check that the input simulator is properly connected.
