INTRODUCTION
This instrument is a portable 3
digital thermometer designed to use external K-type
thermocouple as temperature
indication follows National Bureau of Standards and
IEC584 temperature/voltage
thermocouples. One 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
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 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 "Input protection" in this manual.
