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)
6.1.2 Setting the DC generator voltage level
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).
6.1.3 Generating Ramp-Up or Ramp-Down DC output cycles
Ramp up generator example: Set A = 5V; B = 10V;
Δt
a-b = 5 seconds
1.
Connect a suitable load to the output and turn ON the output by pressing the “OUTPUT
ON/OFF” button; note the output LED indicator.
2.
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).
3.
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.
