Vout is the power supply output voltage. Vin is the programming voltage.

Programming Voltage Common to the Minus Output

Figure 2

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

Vin = 1/A x Vout

Vout = A x Vin

Where	Vout is the power supply output voltage.
	Vin is the programming voltage.
	A is the gain factor and the values of each model are as below.

	Model	A	1/A

	E3614A	0.44	2.25

	E3515A	0.67	1.5

	E3616A	0.78	1.29

	E3617A	0.86	1.17

Alternative Voltage Programming Using Resistors

Programming Voltage Common to the Plus Output

Figure 3

The M/S2 switch must be in the down position. For best results, place a 0.1μF capacitor in parallel with R2.

Vin = (R1/R2) x Vout

Vout = (R2/R1) x Vin

Where

R1 and R2 should be in the 1KΩ to 100KΩ range.
