Thermocouple Thermometer
INTRODUCTION
This instrument is a portable 3
compact-sized digital thermometer designed to
use external K-type thermocouple as temperature
sensor. Temperature indication follows National
Bureau of Standards
temperature/voltage tables
thermocouples. two K-type thermocouples is
supplied with the thermometer.
SAFETY INFORMATION
It is recommended that you read the safety and
operation instructions before using the thermometer.
WARNING
TO AVOID ELECTRICAL SHOCK. DO NTO
USE THIS INSTRUMENT WHEN VOLTAGES
AT THE MEASUREMENT SURFACE EXCEED
24V AC OR 60V DC.
WARNING
TO AVOID DAMAGE OR BURNS. DO NOT
MAKE TEMPERATURE MEASUREMENTS IN
MICROWAVE OVENS.
CAUTION
Repeated sharp flexing
thermocouple leads. To prolong lead life, avoid
sharp bends in the leads, especially near the
connector.
The symbol on the instrument indicates that
the operator must refer to an explanation in this
manual.

OPERATING INSTRUCTIONS
Selecting the Temperature Scale
Readings are displayed in either degrees Celsius
( ℃ ), degrees Fahrenheit ( ℉ ).When the
can break 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 For℃ or ℉key.
