INTRODUCTION
This instrument is a portable 3½ digit, compact-sized
digital thermometer designed to use external K type and J
type thermocouples. It also has the feature that sensor
offset can be adjusted for in the field. There are 2 inputs
for miniature thermocouple connectors at the top of the
instrument marked T1 and T2.
SAFETY INFORMATION
It is recommended that you read the safety and opera-
tion instructions before using the thermometer.
WARNING
To avoid electrical shock, do not use this instrument
when working voltages at the measurement surface
over 24V AC or DC.
WARNING
To avoid damage or burns, do not make temperature
measurement 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.
