If battery indicator turns on, battery life is approxi-
mately8 to 10 hours.Thebatteryindicator will start
blinkingwith less than 1 hour of liferemaining.
ATTHISPOINT,BATTERYMUST BE CHANGED.
IF BATTERY VOLTAGE GOES TOO LOW, DIS-
PLAY WILL GO BLANK.
SeeSPECIFICATIONS forbattery type.
1. Beforechanging battery, turninstrument offand
disconnectthermocouple.
2. Loosen screw and lift battery cover off back of
case.
3. Removethe two AA batteries.
4. Insert twonewbatteries observing polarity.
5. Install cover and tighten screw.

CONNECTING A THERMOCOUPLE
Usethecorrect thermocoupletypeforyourinstru-
ment. Using an incorrect thermocouple type will
result in erroneous readings. Thermocouples are
colorcodedbytypeusing theNorthAmerican ANSI
ColorCode as follows:
TYPE COLOR
J Black
K Yellow
T Blue

Donot forceconnector in back-
wards.
Connectthermocouple to receptacle at top
ofinstrument as showninthefollowingillustration.
Thermocouple wiring polarity must be correct. If
readings decrease as the temperature increases,
thethermocouple wires maybereversed. The red
wire is negative for thermocouple wires manufac-
turedin NorthAmerica.
