Users Manual

Selecting a Channel

There are 21 channels, 0 to 20. A channel is selected for configuration or configuration verification when the instrument is in the inactive mode. An active channel is selected for monitoring when the instrument is in the Monitor Mode (see Figure 2-17) or Review Mode (see Figure 2-18). Perform the procedure in Figure 2-3 to select a channel.

Restrictions

Locked Out Channels. Any channel 1 to 10 (n) assigned to four-terminal (4T) measurements locks out a corresponding channel a decade higher (n+10). For example, use of channel 3 for 4T measurements locks out channel 13, which can be selected, but not configured.

Restricted Channels. Channel 0 (front panel terminals) does not support thermocouple measurements or four-terminal measurements.
