4. To return the meter to the operate mode, depress OPR after recalling the
last reading. All active location annunciators will turn on again, together
with the OPR annunciator.
NOTE: Recalling data from unused (ie, empty) locations will give
a zero reading.
To Erase Data Locations (Meter Mode):
1. Individual data locations can be erased by recalling the location to be
cleared, followed by a CLEAR key input. Note that the annunciator for the
cleared location is turned off, and the meter returns to OPR.
eg. RECALL 3
eg. CLEAR
NOTES: There is no need to clear a location if new data is ready
for saving in this location. Just STORE the new data. It will write
over and delete the old.
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, hit the CALIB key to change to the cal-
ibrator 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 selec-
tion, turn the unit off, then on again for another momentary read-
out.
5. Select the desired temperature scale (°F/°C key).
