If battery indicator turns on, battery life is approximately 8 to 10 hours. The battery indicator will start
blinking with less than 1 hour of life remaining.
A T THIS POINT BA TTER Y MUST BE CHANGED .
IF BATTERY VOLTAGE GOES TOO LOW, DISPLA Y WILL GO BLANK.
See SPECIFICA TIONS f or battery type.
1. Before changing battery , turn instrument off and
disconnect thermocouple(s).
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.

CONNECTING A THERMOCOUPLE
Note: Be sure your instrument setting (J, T, E or K)
matches the thermocouple you are using.
Use the correct thermocouple type for your instru-
ment. 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 Yellow
T Blue
E Purple
Thermocouple connectors have one wide blade and
one narrow blade.
wards.
Connect thermocouple(s) to receptacle at
top of instrument.
Do not force connector in back-
If only one thermocouple is being used, it can be
connected to either T1 or T2. The thermometer will
automatically determine which connector is being
used. When two thermocouples are used, connect
one to the T1 connector and one to the T2
connector.
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.
