2. SAFETY PRECAUTIONS
WARNING:
1. This instrument is designed to
accept low level signals supplied
by standard thermocouples. Under
NO circumstances should the input
voltage exceed the specified 50V
RMS.
2. To prevent ignition of a hazardous
atmosphere, batteries must only be
changed in an area known to be
nonhazardous.
CAUTION:
1. Do not use or store this instrument
in microwave ovens or any
abnormally hot or cold areas.
2. Weak batteries should not be left in
the instrument. Dead batteries can
leak and cause damage to unit.
DANGER:
1. Voltages present at the
thermocouple may also be present
at the battery terminals. Always
disconnect the thermocouple
when changing batteries.

4. BATTERY INSTALLATION AND
REPLACEMENT
The total battery life without
backlighting is about 750 hours.
Each bar of the battery annunciator
represents 200 hours. A blinking
empty battery annunciator indicates
150 hours remaining.
Selected settings are stored in
memory and will remain in memory
even after power is turned off, or
while batteries are being replaced.
1. Before changing battery, turn
instrument off and disconnect
thermocouple.
2. Loosen screw and lift battery
cover off back of case.
3. Remove the three AA batteries.
4. Insert three new batteries
observing polarity.
5.
Install cover and tighten screw.
5. INSERTING AND REMOVING
RUBBER ARMOR
1. To insert thermometer into the
optional rubber armor, slide in from
the top of meter before pushing the
bottom edges of meter down to set
it into position. Lift up the stand at
the back of meter for bench top
applications if necessary.
2. To remove thermometer from
armor, push out from the bottom
edges of meter until it is completely
out of boot.

ASSEMBLING OPTIONAL
HANDS-FREE ACCESORIES
You can use the optional magnets and
strap in the Hands-Free Kit accessories
for hands-free operations.
- 8 –
7. SELF TEST
Press the on/off key. The meter
performs a self-test and all display
digits and indicators, should remain
on for approximately one second.
The thermometer will then display
the thermocouple type and resume
to the measurement mode.
8. 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
J
Black
K Yello
w
T Blue
Thermocouple connectors have one
wide blade and one narrow blade.
Do not force connector in backwards.
Connect thermocouple to receptacle
at top of instrument as shown in the
following illustration:
- 9 –
Thermocouple wiring polarity must be
correct. If readings decrease as the
temperature increases, the thermocouple
wires may be reversed. The red wire is
negative for thermocouple wires
manufactured in North America.
9. KEY FUNCTIONS
Toggle between Celsius or
Fahrenheit.
Activates Calibration mode

(after field calibration
enabled).
Activates/deactivates

If a thermocouple is not connected or if
the thermocouple is defective, the
display will indicate “OPEn”.
Thermocouples are sensitive at the tip
or measuring junction. When taking
measurements, allow time for the
reading to stabilize. Multiplying the time
constant of the probe by 5 will give you
the approximate time required.
11. SELECTING TEMPERATURE
SCALE
Select °C or °F by pressing the °C/°F
key. Each time the key is pressed the
temperature scale will switch. Switching
between °C and °F can be done at any
time during operation.
Each time you turn the instrument on,
it will power up with the same settings
that were set when the unit was last
turned off.
12. HOLD FUNCTON
Press
the
hold key
to
retain
the
reading on
the

y.
Press
the
hold key again
for

13. MIN AND MAX FUNCTION
Press the min/max key to toggle
between the minimum and maximum
readings. This function is ideal for
monitoring unattended operations while
continually displaying every temperature
change that occurs. The minimum and
maximum values are sensed and
automatically stored.
To exit and clear this function, press
the min/max key for 3 seconds.
14. AUTO OFF FUNCTION
The thermometer has a default auto off
function of 17.5 minutes.
To deactivate this function, press and
hold the min/max key while turning on
the meter using the on/off key.
“A.OFF nO” will appear indicating that
the auto off function is disabled.
15. CALIBRATION
The thermometer is factory calibrated
and does not require calibration before
use. The Calibration function allows
single-point calibration of the meter 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
- 14 –
improve thermometer/probe accuracy or
to compensate for thermocouple drift.
1. Pack sensing end of probe in a
container tightly packed with
crushed ice and filled with distilled
water. Allow temperature to
stabilize.
2. Press and hold the cal key for
3 seconds to enter the calibration
mode, the CAL annunciator on the
display starts blinking. Release
the cal key.
3. If the measured temperature is from
–
10 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 reading will be set to 0°C
(32°F). The CAL indicator will remain
turned on, indicating a field calibration
is active.
If “Err CAL” is displayed, either the
displayed reading is outside the above
limits or the batteries are weak.
16. CANCELING A FIELD
CALIBRATION
1. Turn the thermometer off.
2. Hold the cal key down while
pressing the on/off key. The field
calibration is cancelled and the
thermometer reverts to the default
factory calibration. The CAL
annunciator is now turned off.
- 15 –
17. FIELD CALIBRATION LOCKOUT
AND RE-ENABLE
The calibration lockout feature prevents
any field calibration changes. The
lockout remains in effect until a lockout
re-enable has been performed. Use the
following procedures to lockout or reenable the field calibration operation.
LOCKOUT PROCEDURE
1. Turn the thermometer off.
2. Simultaneously press and hold
the cal and the °C/°F keys down and
momentarily press the on/off key.
Continue to hold the cal and °C/°F
keys
until the measurement mode is
displayed.
RE-ENABLE PROCEDURE
1. Turn the thermometer off.
2. Simultaneously press and hold
the hold and the cal keys down and
momentarily press the on/off key.
Continue to press the hold and cal
keys until the measurement mode is
displayed.
- 16 –
18.
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.
19. CLEANING
WARNING:
TO PREVENT IGNITION OF A
HAZARDOUS ATMOSPHERE BY
ELECTROSTATIC DISCHARGE,
CLEAN WITH DAMP CLOTH.
Do not clean with abrasives or solvents.
Use mild detergents, never immerse
nor use excessive fluid.
20. BATTERIES
If there is no display when the
thermometer is turned on, check
condition of the three 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.
