Use SENSE HI and SENSE LO terminal connections to measure
voltage at the device under test (DUT). When you use sense leads,
measurement of the voltage drop across the force leads is
eliminated. This produces more accurate voltage sourcing and
measurement at the DUT.
Use FORCE HI and FORCE LO terminal connections to source or
sink voltage or current to or from a device under test (DUT).
Activates the terminals on the front or rear panel. When the front-
panel terminals are active, a green "F" is visible to the left of the
