Agilent Technologies 5951-2826 manual +S and -S, IM and VM, Pins 3, Common, Ext Prg pin, Flt pin

+S and -S	Used to connect the remote sense leads to the power source. Pin 1 connects the + S signal and pin 2
	connects the - S signal.
IM and VM	Used to monitor the Electronic Load’s input current and voltage. A 0 V-to-10 V signal at the
(pins 3 and 4)	appropriate pin indicates the zero-to-full scale current or voltage. Pin 3 monitors current (IM); pin 4
	monitors voltage (VM).
Common	Provides the common connection for the IM, VM, and external programming (Ext Prg) signals. This
(pin 5)	common point is floating from ground at the potential of the - INPUT terminal.
Ext Prg (pin 6)	Connects an external programming input. The CC and CV mode can be programmed with a 0 V-to-10
	V signal (ac or dc). This signal can act alone or can be summed with values programmed over the
	GPIB. Thus, it is possible to have an ac signal applied at pin 6 upon a programmed dc level.
Pin 7	Not used.
Flt (pin 8)	A TTL-compatible output signal that becomes active (high level) when an overvoltage or a reverse
	voltage condition occurs. This signal powers up in the inactive (low-level) state.
Port (pin 9)	A TTL-compatible output signal that becomes active (high level) when the PORT0 command is
	programmed ON. This signal can be used to control an external device such as a relay for shorting the
	Electronic Load’s input terminals or as a general purpose digital output port. This signal powers up in
	the inactive (low-level) state.
Common	Provides the common connection for the Flt and Port signals.

Replace the mating plug in the connector after you have finished making all wire connections. Replace the safety cover.
