INTRODUCTION

This instrument is a 4½ digit, compact-sized portable digital thermometer
designed to use external 100W Platinum RTD as temperature sensor. Tem­perature indication follows Reference Temperature/Resistance Tables (Pt385
for European Curve, Alpha=.00385 and Pt3926 for American Curve, Al­pha=.003926).

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.

The symbol on the instrument indicates that the operator must refer to
an explanation in this manual.
