6. Supplemental Functions

6.1 ΔV/Δt Function

There are 3 DC voltage generator settings (A, B, and C).

Preset 1 = A

Preset 2 = B

Preset 3 = C

ΔV a-b (from voltage level A to voltage level B).

Δt a-b (time in seconds from voltage level A to level B, this transit time is adjustable from 0 to 20

seconds)

There are 3 generator voltage levels presets (A, B, and C).

Press the Preset button 1, 2 and 3 and adjust the voltage to the desired value.

6.1.2 Setting the Δt

There are 6 sets of Δt available , turning the Voltage control knob cycles through the following

sequence: AB →BA →AC →CA →BC →CB

Using the AB setting as an example, turn the Voltage control knob until A-b appears on the

voltmeter display and then turn the Current control knob to set to desired transit time Δt (5

seconds for example).

Ramp up generator example: Set A = 5V; B = 10V; Δt a-b = 5 seconds

Connect a suitable load to the output and turn ON the output by pressing the "OUTPUT

ON/OFF" button; note the output LED indicator.

Push "Preset 1" and note the output voltage of 5V. Press "Preset 2" and note that the

output voltage rises to 10V in 5 seconds showing a ramp up voltage (the output will

remain at 10V).

Pressing "Preset 1" will now generate a ramp down voltage from 10V to 5V in 5 seconds

and will remain at the 5V level.

Note: The final output voltage level will be the last voltage level generated.
