Error recovery:
See section 5.6 (page 60) for details. Insure that the millivolt source is connected correctly
and functioning properly.

The calibration can be exited when hLd1 or the calibration reference number is displayed by
pressing the SCROLL key.

CAL2 QUICK CALIBRATION

This routine will allow the operator to execute a rough calibration on their unit via the keypad
with no other equipment or disturbance to established wiring.  It is intended to provide a partial
recovery from a calibration corruption where the necessary equipment indicated may not be
available.  It should be noted that this is not intended as a substitution to the main calibration
procedure described earlier and may deter considerably from the accuracy of the instrument.

With CAL2 displayed, press and hold the DOWN ARROW key, then press the SCROLL key.
Release both keys and the instrument will display hLd1.  Press and hold the UP ARROW key,
then press the SCROLL key.  The display will momentarily blank and then CAL1 will be
displayed.  Release both keys and depress the UP ARROW key.  CAL will be displayed.

5.4.3

CAL 3 COLD JUNCTION COMPENSATION

This routine determines and saves calibration values which correct for component variations
relating to the cold junction compensation. This calibration must be preceded by CAL 2 the
main calibration, to properly calibrate the instrument. These two calibrations are all that is
needed for proper operation with thermocouple inputs.

Test equipment: 1-type J thermocouple

1-mercury thermometer 

±

 .25 degrees F or equivalent

Allow 30 minutes of warm up time for the instrument with the thermocouple connected
before proceeding with calibration.

Operation:
With CAL 3 displayed press and hold the DOWN key, then press the SCROLL key . Release
both keys and the instrument will display hoLd. Connect the J thermocouple to TB 4 terminals
1 and 2 and place the thermometer  inside the case at the bottom of the instrument.  Short the
input terminals TB5, 1 and 2.  Press the DOWN key, deLy will be displayed for about 10
seconds, then SCAn for 10 seconds. The  display will be the temperature to the nearest tenth
of a degree C. Compare the display reading with thermometer and use the UP and DOWN
keys to correct the reading. To exit press the SCROLL key and CAL 3 will be displayed again.

If the display stays in  SCAn for more than 15-20 seconds,  press the SCROLL key.  CAL3
should be displayed.  With CAL3 displayed, while pressing the DOWN key, press the
SCROLL key.  The instrument will display  hoLd. Press the UP key.  The instrument will begin
the calibration procedure with a default calibration value and proceed to dELy as described .

Error recovery:
See section 5.6 (page 60) for details on specific errors. The calibration can be exited if hoLd
or the CJC temperature is displayed by pressing the SCROLL Key.

5.4.4

CAL 4 COLD JUNCTION UTITILITY

This procedure displays the temperature the cold junction compensator is sensing. No test
equipment is required.

With CAL 4 displayed press and hold the DOWN key, then press the SCROLL key . Release
both keys and SCAn will be displayed for 10 seconds while the instrument senses the CJC
temperature. The result will then be displayed to a tenth of a degree C. The input terminals
must be shorted.  CAL 3 must first be performed. 

The displayed temperature is not the

ambient temperature. It is the temperature of the CJC . To exit, press the SCROLL key
and CAL 4 will be displayed.
