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
Thermocoupleconnectorshaveonewidebladeand
onenarrowblade. 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.

2. Ifathermocoupleis not connected or if the ther-
mocouple is defective, the display will indicate
OPEn.
3. Select °C or °F by pressing the°C/°F key.Tem-
peraturescale can be switchedat anytime. The
thermometer remembers the lastselectedscale
the next time you turn the power on.
4. For optimum instrument accuracy, allow one
minuteforambient temperaturestabilization. If
theunithas been stored at an extremeambient
condition,moretime will be needed.
Thermocouples are sensitiveat the tip or measur-
ing junction. When taking temperature measure-
ments,allow time forthe readingto stabilize. Mul-
tiplyingthetime constant of the probe by5willgive
youthe approximatetime required.
Notethatthe readings will automatically change to
1°resolutionbelow–99.9° orabove299.9°.
If desired, press the HOLD key to retain the read-
ing on the display.Press HOLD key again for nor-
maloperation.
If the display shows "- - - -" the temperature read-
ing is out of range of the instrument.
OPERATION
Note: Be sure the thermocouple you are using
matchestheinstrument setting indicated on the
unit.
1. Press the ON/OFF key.The thermometer per-
forms a self-test and all display digits and indi-
cators, as shown below, should remain on for
approximatelytwoseconds.

FIELD CALIBRATION
Thethermometerisfactorycalibratedanddoesnot
require calibration before use.The CAL function
allowssinglepointcalibrationofthethermometer,
at0°C(32°F)to compensate forthermocouple off-
seterror.It is notnecessarytoperform a field cali-
brationto obtain specified meter accuracy.Use the
field calibration feature to improve thermometer/
probeaccuracy ortocompensateforthermocouple
drift.
1. Follow steps 1 through 4 in OPERATION sec-
tion.
2. Packsensing 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
enterthe calibrationmode,the CALannunciator
on thedisplaystarts blinking. Release the CAL
key.
4. If the measured temperature is from −10°C to
10°C (14 to 50°F), when the temperature read-
ing is stable, press theCAL key.
TheCAL indicatorwillstopblinkingandthe read-
ing will be set to 0°C (32°F).The CAL indicator
will remain turned on, indicating a field calibra-
tion is active.
If“Err”isdisplayed,either the displayedreading is
outsidethe abovelimits or the batteries are weak.
CANCELING A FIELD CALIBRATION
1. Turn thethermometer off.
2. Hold the CAL key down while pressing the
ON/OFF key.
Thefieldcalibrationis canceled and the thermom-
eter reverts to the default factory calibration. The
CALannunciatorisnowturned off.

FIELD CALIBRATION LOCKOUT
AND RE-ENABLE

Lockout Procedure
1. Turn thethermometer off.
2. Simultaneously press andhold the CALand the

keys for at least 5 seconds.
Re-Enable Procedure
1. Turn thethermometer off.
2. Simultaneously press and hold the HOLD and
