1.1
Overview
The USB PT-104 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.
