Note: Once the channel input is turned on, the load will not start to sink
the current until the input voltage is greater than the break-over
voltage.
4. View waveform
Press Display key to enter waveform display interface, as shown in
figure 3-13. By means of observe waveform of ExtI mode after set the
Data selection be "I", user can see the trend of the sink current. Press
the Display key again to exit the waveform display interface and return
to the main interface of ExtI mode.
Figure 3-13 Waveform display interface of ExtI mode
ExtV
After selecting "ExtV" tab, the load will enter ExtV interface. It includes Type,
RangeI, RangeV three options. The sink voltage of the load can be
controlled by the "EXT" terminals on in the rear panel of the load. User can
simulate input voltage of the load which range is from zero to full range.
Operating Steps
1. Connect device
Power on instruments and connect the DUT and the channel input
terminals of the electronic load, as shown in Figure 2-2.
Warning
The input voltage range of the "EXT" terminals is 0-10 V. To avoid
damage to the instrument , please pay attention to the polarity of the
device terminals.
