Thermocouple wiring polarity must be correct. If
readings decrease as the temperature increases,
thethermocouplewires maybe reversed. Thered

If the display shows "- - - -" the temperature read-
ing is out of range of the instrument.
OPERATION
Note: Be sure the thermocouple you are using
matchestheinstrument settingindicatedonthe
unit.
1. Press the ON/OFF key.The thermometer per-
forms a self-test and all display digits and indi-
cators, as shown below, should remain on for
approximatelytwoseconds.

1. Follow steps 1 through 4 in OPERATION sec-
tion.
2. Packsensing endof probein acontainer tightly
packed with crushed ice and filled with distilled
water.Allowtemperatureto stabilize.
3. Press and hold the CAL key for 5 seconds to
enterthecalibrationmode,the CALannunciator
on the display starts blinking. Release the CAL
key.
4. If the measured temperature is from −10°C to
10°C (14 to 50°F), when the temperature read-
ing is stable, press the CAL key.
TheCALindicatorwillstopblinkingandtheread-
ing will be set to 0°C (32°F).The CAL indicator
will remain turned on, indicating a field calibra-
tion is active.
If“Err”isdisplayed,eitherthe displayedreading is

CANCELING A FIELD CALIBRATION
1. Turn thethermometeroff.
2. Hold the CAL key down while pressing the
ON/OFF key.
Thefieldcalibrationis canceledand the thermom-
eter reverts to the default factory calibration. The
CALannunciatoris nowturnedoff.
