Agilent Technologies E3614A, E3617A, E3616A, E3615A Remote Resistor Programming Connections

	Voltage and Current Programming of the
	E3614A/15A/16A/17A with Resistors
	Remote programming with resistors permits control of the regulated output or current
	by means of a remotely varied resistor. The sum of the resistance of external
	programming resistors (R1 + R2) should be more than 40 kohm. To have more precise
	output voltage, use a variable resistor more than 40 kohm. The voltage control on the
	front panel is disabled during remote resistor programming.
N O T E	Do not operate the power supply simultaneously in the remote analog voltage
	programming and in the remote resistor programming.
	Remote Resistor Programming Connections
	Remote resistor programming requires changing the setting of the switches and
	connecting external resistors between “+” and “`-” terminals of “CV” and “VREF”
	terminal or “+” and “-” terminals of “CC” and “VREF” terminal. Any noise picked up
	on the programming leads will appear on the power supply's output and may degrade
	regulation. To reduce noise pickup, use a twisted or shielded pair of wires for
	programming, with the shield grounded at one end only.

Set the CV switch down on the rear panel, and all others up.

Vout = A x [VREF x {R/(R + R2 + 100)}]

Where	Vout is the power supply output voltage.
	A is the gain factor and the values of each model are as below.
	VREF is between 10.11 V and 11.40 V.
	R = (92800 x R1)/(92800 + R1)
	R1 + R2 > 40 kohm
	Model	A
	E3614A	0.8
	E3515A	2.0
	E3616A	3.5
	E3617A	6.0
