If battery indicator turns on, battery life is approximately 8 to 10 hours.
See SPECIFICATIONS for battery type.
1. Before changing battery , turn instrument off and
disconnect probe.
2. Loosen screw and lift battery cover off back of
case.
3. Remove the two AA batteries.
4. Insert two new batteries, observing polarity.
5. Install cover and tighten screw.
6
CONNECTING AN RTD
Use the correct 100 ohm RTD (alpha = 0.003850)
for your instrument. Using an incorrect probe type
will result in erroneous readings. Insert the 3-pin
plug into the mating connector on the top of the
instrument.

OPERATION
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.
2. If a probe is not connected or if the probe is defective, the displa y will indicate “oPEn”.
3. Select °C or °F by pressing the °C/°F key. Temperature scale can be switched at any time. The
thermometer retains the last selected scale the
next time you turn the power on.
4. For optimum instrument accuracy, allow one
minute for ambient temperature stabilization. If
the unit has been stored at an extreme ambient
condition, more time will be needed.
When taking temperature measurements, allow
time for the reading to stabilize. Multiplying the time
constant of the probe by 5 will give you the approximate time required.
If desired, press the HOLD key to retain the reading on the display . Press HOLD key again for normal operation.
The display will show “Ur” (under range) or “Or”
(over range) if the temperature reading is out of
range of the instrument.
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 probe 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.
1. Follow steps 1 through 4 in FIELD CALIBRA-
TION CLEAR/UNLOCK section.
2. Pack sensing end of probe in a container tightly
packed with crushed ice and filled with distilled
water. Allow temperature to stabilize.
3. Press and release the CAL key to enter the calibration mode.
4. The display will momentarily show “CA” and then
the temperature reading starts blinking.
5. If the measured temperature is from –5°C to 5°C
(23 to 41°F) when the temperature reading is
stable, press the HOLD key to confirm
calibration.
The display will momentarily show “CO” and the
reading will be set to 0°C (32°F). The CAL indicator will turn on, indicating a field calibration is
active.
The field calibration is automatically
locked as well.
If “Err” is display ed, either the display ed reading is
outside the above limits or the batteries are weak.
11
FIELD CALIBRA TION CLEAR/UNLOCK
The calibration clear/unlock feature will cancel an y
previous field calibration (the thermometer reverts
to the default factory calibration) and also enables
the field calibration operation.
1. Turn the thermometer off.
2. Hold the CAL key down while pressing the ON/
OFF key .
3. Unit will first display 8888 then the firmware version number
4. When the CAL key is released, the unit will return to measurement mode.
FIELD CALIBRA TION LOCKOUT
The calibration lockout feature prevents any field
calibration changes. The lockout remains in eff ect
until a clear/enable has been performed. Use the
following procedures to lockout the field calibration
operation.
Lockout Procedure
1. Turn the thermometer off.
2. Hold the HOLD key down while pressing the ON/
OFF key .
3. Unit will first display 8888 then the firmware version number
4. When the HOLD key is released, the unit will
display 8888 and then turn off. (If field calibration is already locked, the unit will return to measurement mode.)

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.
Do not clean with abrasives or solvents. 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, ref er to the BA TTER Y INST ALLA TION
AND REPLACEMENT section for replacement
procedure.
SERVICE
There are no internal adjustments or userreplaceable parts.
Note: Serial number label is located inside
battery compartment.
