Overview
The PT-104 Data Logger is a four-channel, high-resolution temperature converter for
use with PT100 and PT1000 type
platinum resistance thermometers (PRTs). It can be
used to measure temperature, resistance and voltage.
In PT100, PT1000 and resistance modes, the unit can use a two, three or four-wire
circuit. Four-wire measurement gives the greatest accuracy.
In voltage mode, the input connector can be treated as a differential input with
ground, or as two single-ended inputs .
