Figure 2-9 Main Interface of CR Mode
3. Set CR mode current range (5 A or 30 A), voltage range (36 V or
150 V) and resistance range (Low/Middle/High/Upper).
Note:
The low range provides better resolution and accuracy at
low resistance settings.
4. Set the target resistance value
5. Press On/Off to turn on the channel input. At this time, the actual
input voltage, current, resistance and power will be displayed on
the main interface.
Note:
The load will begin to sink current only if the input voltage is
greater than the conduction voltage of the system (default value
is 0 V)
Warning
To avoid electrical shock, ensure that the DUT is connected to the
input terminals of the load properly before you turn on the channel
input.
6. Press the Display key to enter the waveform display interface, as
shown in Figure 2-10. By default, the resistance waveform is
displayed. When the input voltage changes, the load current will
linearly change. Press the Display key again to exit the waveform
display interface and return to the main interface of CR mode.
