Programmable DC Electronic Load 63600 Series Operation & Programming Manual
4.7.1 Setup of System Configuration
Turn the Rotary knob to change the display value to 1, then press
page of system configuration.
Set the voltage range of CC mode. There are three voltage ranges for CC mode. High
range is for high voltage, middle range is for middle voltage, and low range for low voltage so
as to get better voltage resolution. The default setting of Vrange is HIGH.
Set Von point. Von is the conduction voltage level when the Electronic Load starts to sink
current and the UUT output reaches the Von voltage. The default setting for Von voltage is
0V.
Set Von latch. There are two operation modes for Von control. Von latch ON means the
Load will sink current continuously when it reaches Von voltage. Von latch OFF means the
Load will stop sinking current when UUT voltage is under Von voltage. The default setting of
Von latch is OFF. Figure 4-8 and Figure 4-9 show the Von LATCH ON and OFF current
waveform respectively.
If the Von_POT is too small and it is loading under the minimum working
CAUTION
voltage, it will get overshoot spike. If a UUT is applied, the overshoot
may damage the UUT regardless of how small setting the Load current
specified. So it is necessary to consider if it meets the minimum working
voltage when setting the Von_POT to avoid having exceeding overshoot
spike.
