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.
