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.
