OPERATING INSTRUCTIONS
Selecting the Temperature Scale
Readings are displayed in either degrees Celsius (°C)
or degrees Fahrenheit (°F). When the thermometer
is turned on, it is set to the temperature scale that was
in use when the thermometer was last turned off. To
change the temperature scale, press the °C or °F key.
Selecting the Display Resolution
The thermometer allows two choices of resolution:
High resolution: 0.1°C or 0.1°F
Low resolution: 1.0°C or 1.0°F
To select the alternate display resolution, press the
corresponding "1°" or "0.1°" key.
The 0.1° resolution is applicable for temperature
measurements below 200°C or 200°F.
HOLD Mode
Pressing the HOLD key to enter the Data Hold mode,
the "HOLD" annunciator is displayed. When HOLD
mode is selected, the thermometer holds the present
readings and stops all further measurements.
Pressing the HOLD key again cancels HOLD mode,

measurements.
MIN/MAX Mode
Press MIN / MAX once to begin recording MIN and
MAX. Press MIN / MAX to select MIN or MAX.
Hold down for 2 seconds to exit MIN / MAX
function.
OFFSET ADJUSTMENT
The OFFSET control is set at the factory to allow for
the variations found in standard thermocouples. By
adjusting the OFFSET control, you can optimize
measurement accuracy for a particular thermocouple
at a particular temperature.
Adjusting for Accurate Measurements
1.Connect the thermocouple to the input connector
and turn the thermometer ON, then press the 0.1°
key to select the high display resolution.
2.Place the thermocouple in a known , stable tem-
perature environment at or near the temperature
you wish to measure , and allow the readings to
stabilize.
3.Slowly adjust the OFFSET control so that the ther-
mometer reading matches the temperature of the
known environment. Leave sufficient time be-
tween adjustments to allow for measurement lag.
4.The calibration of the thermometer-thermocouple
combination is now optimized for measurements
near the temperature measured in step 2.
Resetting the OFFSET Control
To return the OFFSET control to the factory setting
without having to recalibrate the thermometer, per-
form the following procedure:
1.Connect a thermocouple that is in good working
order to the input that is to be adjusted.
2.Place the thermocouple in an ice-water bath and
allow the readings to stabilize.
3.Slowly adjust the OFFSET control until the ther-
mometer reads 0°C (32°F)

ON when thermocouple probe is attached, check the
thermocouple probe which might be damaged.
OPERATOR MAINTENANCE
WARNING
TO AVOID POSSIBLE ELECTRICAL SHOCK,
DISCONNECT THE THERMOCOOUPLE
CONNECTORS FROM THE THERMOMETER
BEFORE REMOVING THE COVER.
Battery Replacement
Power is supplied by a standard 9 volt battery (NEDA
1604,IEC 6F22). The "
" appears on the LCD dis-
play when replacement is needed. To replace the
battery, remove the screw from the battery cover of
the meter. Remove the battery and replace with a new
equivalent 9 volt battery.
