I. Introduction:
This instrument is a four channel digital thermometer for use with any K-type thermocouple as
temperature sensor. Temperature indication follows National Bureau of Standards and IEC584
temperature/voltage table for K-type thermocouples. It internal memory can keep up to 16,000
records per channel. (note1.) It uses RS232 interface to perform bi-directional communication with
PC.

note1:
Every time you press "REC" button to start recording data and press "REC" button again to stop
recording, there will be a data set in memory, you can store as many data sets as you want until memory
is full.
Temperature Coefficient:
For ambient temperatures from 0°C ~ 18°C and 28°C
~ 50°C, for each °C ambient below 18°C or above
28°C add the following tolerance into the accuracy
spec.
0.01% of reading + 0.03°C
