Sense mode selection
When the pulser is disabled, the voltage sense mode can be set to use 2-wire local sensing
connections (on page 4-10) or 4-wire remote sensing connections (on page 4-10). The default sense
setting is 2-wire local.
When the pulser is enabled, the sense mode is fixed at 4-wire remote sensing and the sense mode
settings are ignored.

To check or change the voltage sense mode from the front panel:
1. Press the CONFIG key.
2. Press the SRC or MEAS key. You can access and set the 2601B-PULSE sense mode from either
