If battery indicator turns on, battery life is appro ximately 8 to 10 hours. The battery indicator will start
blinking with less than 1 hour of life remaining.
AT THIS POINT , BATTER Y MUST BE CHANGED .
IF BATTERY VOLTAGE GOES TOO LOW, DISPLAY WILL GO BLANK.
See SPECIFICATIONS for battery type.
1. Before changing battery , turn instrument off and
disconnect thermocouple.
2. Loosen screw and lift battery cover off back of
case.
3. Remov e the two AA batteries.
4. Insert two new batteries observing polarity.
5. Install cov er and tighten screw .

CONNECTING A THERMOCOUPLE
Use the correct thermocouple type for your instrument. Using an incorrect thermocouple type will
result in erroneous readings. Thermocouples are
color coded by type using the North American ANSI
Color Code as follows:
TYPE COLOR
JBlack
K Yellow
T Blue
Thermocouple connectors have one wide blade and
one narrow blade .
Do not force connector in bac k-
wards.
Connect thermocouple to receptacle at top
of instrument as shown in the follo wing illustration.
Thermocouple wiring polarity must be correct. If
readings decrease as the temperature increases,
the thermocouple wires may be rev ersed. The red
wire is negative f or thermocouple wires manufactured in North America.

2. If a thermocouple is not connected or if the thermocouple is defective, the display will indicate
OPEn.
3. Select °C or °F by pressing the °C/°F key. Tem-
perature scale can be switched at an y time. The
thermometer remembers the last selected scale
the next time y ou turn the power on.
4. For optimum instrument accuracy, allow one
minute for ambient temper ature stabilization. If
the unit has been stored at an extreme ambient
condition, more time will be needed.
Thermocouples are sensitive at the tip or measuring junction. When taking temperature measurements, allow time f or the reading to stabilize. Multiplying the time constant of the probe by 5 will give
you the appro ximate time required.
Note that the readings will automatically change to
1° resolution below –99.9° or abov e 299.9°.
If desired, press the HOLD key to retain the reading on the display. Press HOLD ke y again for normal operation.
If the display sho ws "- - - -" the temperature reading is out of range of the instrument.
OPERATION
Note: Be sure the thermocouple you are using
matches the instrument setting indicated on the
unit.
1. Press the ON/OFF key. The thermometer performs a self-test and all display digits and indicators, as shown below, should remain on for
approximately two seconds .
11
FIELD CALIBRATION
The thermometer is factory calibrated and does not
require calibration before use. The CAL function
allows single point calibration of the thermometer ,
at 0°C (32°F) to compensate for thermocouple offset error . It is not necessary to perform a field calibration to obtain specified meter accuracy . Use the
field calibration feature to improve thermometer/
probe accuracy or to compensate for thermocouple
drift.
1. Follow steps 1 through 4 in OPERATION sec-
tion.
2. Pac k sensing end of probe in a container tightly
packed with crushed ice and filled with distilled
water . Allow temperature to stabilize.
3. Press and hold the CAL key for 5 seconds to
enter the calibration mode, the CAL annunciator
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 reading is stable, press the CAL key.
The CAL indicator will stop blinking and the read-
ing will be set to 0°C (32°F). The CAL indicator
will remain turned on, indicating a field calibration is active.
If “Err” is display ed, either the displayed reading is
outside the above limits or the batteries are weak.
CANCELING A FIELD CALIBRA TION
1. Turn the thermometer off .
2. Hold the CAL key down while pressing the
ON/OFF key.
The field calibration is canceled and the thermometer rev erts to the default f actory calibration. The
CAL annunciator is now turned off.
12
FIELD CALIBRA TION LOCKOUT
AND RE-ENABLE
The calibration lockout f eature, pre v ents any field
calibration changes. The lockout remains in eff ect
until a lockout re-enab le has been performed. Use
the following procedures to loc kout or re-enable the
field calibration operation.
Lockout Procedure
1. Turn the thermometer off .
2. Simultaneously press and hold the CAL and the
°C/°F keys do wn and momentarily press the ON/
OFF key. Continue to hold the CAL and °C/°F
keys f or at least 5 seconds.
Re-Enable Procedure
1. Turn the thermometer off .
2. Simultaneously press and hold the HOLD and
the CAL keys do wn and momentarily press the
ON/OFF key. Continue to hold the HOLD and
CAL keys until the displa y blanks.
13
MAINTENANCE
Properly used, the thermometer should maintain
calibration indefinitely and not require service other
than occasional cleaning of the housing and changing of the batteries.
CLEANING
TO PREVENT IGNITION OF
A HAZARDOUS ATMOSPHERE BY ELECTROSTATIC DISCHARGE,
CLEAN WITH DAMP CLOTH.
Do not clean with abrasives or solv ents. Use mild
detergents, nev er immerse nor use excessive fluid.
BATTERIES
If there is no display when the thermometer is
turned on, check condition of the two AA batteries.
Also check that the battery terminals are clean and
batteries are properly installed. If replacement is
necessary , refer to the BATTERY INSTALLATION
AND REPLACEMENT section for replacement
procedure.
