Figure 3. Display Test
2. INITIAL TURN ON
Turn on the instrument by depressing the ON-OFF keyswitch once (Figure
2). At power-up, the unit first performs a display test. All segments and
annunciators of the liquid crystal (LCD) are momentarily turned on for visual
confirmation by the user (Figure 3).
NOTE: In case of missing or poor-contrast segments, contact
factory.
If the unit is turning on for the first time after a new battery is installed, it will
automatically default to the METER mode (ie. temperature measurement
operation). It also defaults to K-type thermocouples, and °F readings with
0.1° resolution. The corresponding LCD annunciators are enabled:
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
