INTRODUCTION

This instrument is a 4½ digit, compact-sized portable digital thermometer
designed to use external K/J/T/E/R/S/N-type thermocouples as temperature
sensor. Temperature indication follows Reference Temperature/Voltage Tables
(N.I.S.T. Monograph 175 Revised to ITS-90) for K/J/T/E/R/S/N-type thermo­couples. Two K-type thermocouple are 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 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.
The symbol on the instrument indicates that the operator must refer to an

explanation in this manual.

OPERATING INSTRUCTIONS

1

Power Switch

The key turns the thermometer on or off. In the MIN MAX record mode
can not power off, must leave MIN MAX record mode then power off.

2

°C/°F Selecting the Temperature Scale

Readings are dual displayed in either degrees Celsius(°C) or degrees
Fahrenheit(°F). When 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 °C/°F key.

3

HOLD Mode (only Main display)

Pressing the HOLD key to enter the Data Hold mode, the "HOLD" annun­ciator is displayed. When HOLD mode is selected, the thermometer held
the present readings and stops all further measurements.
Pressing the HOLD key again to cancel HOLD mode causing thermometer
to resume taking measurements.
In the MIN/MAX recording mode, press HOLD key to stop the recording.
Press HOLD key again to resume recording. (Previously recorded reading
are not erased).
