DIGITAL THERMOMETER
INTRODUCTION
This instrument is a 4 1/2 digit, compact-sized portable digital cali-
brator thermometer designed to use external K/J/T/E/R/S/N/L/U/
B/C type thermocouples as temperature sensor. The thermometer
features a dual thermocouple input, an adjustable T/C offset. The
thermocouples types comply with the(N.I.S.T. Monograph 175 Re-
vised to ITS 90 standard).
WARNING
To avoid electrical shock, do not use this instrument when work-
ing 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 pro-
long lead life, avoid sharp bends in the leads, especially near the
connector.
SAFETY INFORMATION
It is recommended that you read the safety and operation instruc-
tions before using the thermometer.
GENERAL SPECIFICATIONS
Displays:
There are three displays Main Second and Third. The Main and
Second display panels are 4 1/2 digit liquid crystal display (LCD)
with maximum reading of 19999, The main is used for displaying
the value of T1, T2 or output setting. The second displays T1 or T2
readings and the third T1-T2 and groups settings.
