NOTE

All channels (0 through 20) can accommodate 2-terminal resistance measurements. Channel 0, with only two connections, cannot be used for 4-terminal measurements. Four-terminal resistance measurements can be defined for channels 1 through 10 only. Channels 11 through 20 are used, as required, for 4-terminal to provide the additional two connections. For example, a 4-terminal set up on channel 1 uses channels 1 and 11, each channel providing two connections.

Channel Integrity Test

Ensure that the Accuracy Verification Test for channel 0 meets minimum acceptable levels before performing this test.

1.Switch OFF power to the instrument and disconnect all high voltage inputs.

2.Remove the Input Module from the rear of the instrument. Open the Input Module and connect a pair of test leads to the H (high) and L (low) terminals of channel 1. Reinstall the Input Module into the instrument.

3.Connect the ends of the test leads together to apply a short (0 ohms).

4.Reconnect power and switch the instrument ON.
