INTRODUCTION
This instrument is a portable 3½ digit, compact-sized
digital thermometer designed to use external K-type
thermocouple as temperature sensor. Temperature
indication follows National Bureau of Standards and
IEC 584 temperature/voltage tables for K-type
thermocouples. One K-type thermocouple is sup-
plied with the thermometer.
SAFETY INFORMATION
It is recommended that you read the safety and op-
eration instructions before using the thermometer.
Designed to meet IEC-1010-1, CE-EMC.
WARNING
TO AVOID ELECTRICAL SHOCK, DO NOT 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 MICRO-
WAVE OVENS.
CAUTION
Repeated sharp flexing can break the 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.
