Warning

Inputs may be connected to live voltages. To avoid electric shock, remove inputs from live voltages before opening this module.

1.Remove the module from the rear panel by pressing the release tab on the bottom of the module and then pulling the module out of its connector.

2.Loosen the two large screws on top and open the module

3.Connect the wires to H (high) and L (low) for each channel.

4.Thread these wires through the strain-relief pins and out the back of the module.

5.Close the module cover, secure the screws, and insert the module in the connector at the rear of the instrument until it latches in place.

Note

Channel 0 on the front panel does not support thermocouple measurements.

Resistance and RTD measurements can be made with two terminals (one channel) or four terminals (two channels). The four-terminal connection provides increased accuracy (nominal 1%) over the two-terminal connection. Refer to Figure 1-6.
