METER: (unit functioning as a thermometer)

K: (K-type thermocouple)

°F: (Fahrenheit readings)

OPR: (Instrument is operational)

If no input thermocouple is connected to the unit at this time, the numeric

segments will indicate "OPEN".

Plugging a thermocouple into the meter jack (connector T2, on the top right

side) will give actual thermocouple temperature readings.

NOTE: To obtain full accuracy, allow 1-2 minutes after connect-

ing a thermocouple plug, for thermal setting.

If the instrument is to be used as a thermometer or ohmmeter, refer to the

Meter Mode Operation section for detailed instructions. For use as a tem-

perature-calibrator or ohms simulator, refer to Calibrator Mode Operation.

3. METER MODE OPERATION (Thermocouples)

Set-Up:

1. Turn on instrument by depressing the ON/OFF key.

2. Check that the BAT annunciator turns off following the power-up LCD test.

If it does not turn off, less than 10% of battery remains. Refer to Battery

Installation/Replacement instructions.

3. If the meter is already in the METER mode, the METER annunciator will

be on. Otherwise the calibrator mode is enabled and the CALIB annunci-

ator is on. Depress the METER key to return to meter mode.

4. Connect an input thermocouple (TC) to connector T2. Select the appro-

priate TC Type with the select-key. A display annunciator will indicate the

selected TC-type.

NOTE: Space and legibility constraints on the display preclude

the use of dedicated annunciators for the less common tungsten-

rhenium thermocouple types (G, C & D). Instead, these types are

annunciated momentarily on the alpha-numeric display when first

selected. Both T and R annunciators remain on to indicate a

Tungsten-Rhenium selection. To recall the actual G, C, D selec-

tion, turn the unit off, then on again for another momentary read-

out.

5. Select temperature scale with °F/°C key. The corresponding annunciator

is enabled.
