FIGURE 5-2. Interfacing the Pt-100 Using the 4WPB100 Module

The four radiation outputs can be measured using Differential or Single-Ended

inputs on the datalogger. A differential voltage measurement (Instruction 2) is

recommended because it has better noise rejection than a single-ended

measurement. When differential inputs are used, jumper the low side of the

input to AG or

to keep the signal in common mode range.
