GENERAL INFORMATION
6. CALIBRATOR MODE OPERATION (Thermocouples) Set-Up:
1. Turn on the instrument by depressing the ON/OFF key.
2. Check that the BAT annunciator turns off after display check. If not, refer to Battery
Installation/Replacement instructions.
3. When operating as a calibrator, the display indicates CALIB. Should the instrument be
in the METER mode, press the CALIB key to change to the calibrator function.
4. Select the thermocouple type that will be used.
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 selection,
turn the unit off, then on again for another momentary readout.
5. Select the desired temperature scale (°F/°C key).
6. Select the resolution desired (0.0.1 key).
NOTE:
With 1° resolution, one less key stroke will be required to enter
calibrator output temperatures via the keypad.
7. The unit accepts numeric inputs by first changing the keypad to its number-entry mode (NUM)
by depressing the CHANGE/ENTER key once.
The numeric display will flash, the OPR annunciator will turn off, and the NUM annunciator will
turn on. Key in desired temperature value, most significant digit first. After the desired
temperature value is keyed in, press CHANGE/ENTER to return to OPR mode.
To enter a value of 212° with 0.1° resolution, the following keystrokes are used:
CHANGE/ENTER, 2, 1, 2, 0, CHANGE/ENTER
NOTES:
• Invalid numeric entries (eg. a temperature beyond the span of the
selected TC type) will cause a corresponding error code to be
displayed.
• To enter negative (ie. minus) temperatures, press the -0 key first
when in the NUM mode. The first press on this key enters the negative
sign. Subsequent presses enter zeros.
•
To correct a numeric entry while in the NUM mode, press the
CHANGE/ENTER key twice. This will return number entry to the
beginning of a new number.
