The delay time spec for Von is 300µs.
3.10 Short On/Off
Load module can simulate a short circuit at input by setting the load on with full-scale current.
The short circuit can be on/off from the front panel or via remote control. There are two
operations for key on the front panel. One is toggled on/off, and the other is
controlled by key. They are selected in configuration. The key will be enabled only
when Load is ON.
Toggled on/off means pressing once to enable short circuit, and again to disable.
Controlled by key means pressing and holding it to enable short circuit, and
releasing it to return to normal operation.
The actual value of electronic short depends on the limit is the maximum current range and
the maximum power range the Load can supply. Turning on the short circuit does not affect
the programmed setting, and Load input will return to the previous programmed values when
the short circuit is turned off.
In order to simulate a real short circuit, the electronic short function is
only available in each mode for High current range, but not available in
Low and Middle current range.
3.11 Digitizing Function
To record the transient voltage and current waveforms, the 63600 series offer a digitizing
function for recording the transient waveforms. It is very convenient to record the information
via this function.
In the page of system configuration, turn the Rotary knob to change the display value to 9,
then press key into Digitizing Function edit page of system configuration.
Set the Sampling Time
. Set the interval of sampling time. The range is from 2
μs to 40ms,
and the resolution is 2
μs. If
Set the Sampling Point is 4097 to 15,000 dots, the setting
range is 100
μs - 40ms
and the resolution is 100
μs. The default of Sampling Time is 40mS.
SAMPLING_TIME
: 40.000ms
Set the Sampling Point . Set the total sampling points. The range is from 1 to 15,000 points.
The default of Sampling Point is 4,096 points.
