Set V_Limit
The upper limit of the voltage working in CV mode. The default unit for V_Limit
is V, and it ranges from 0 V to 180 V.
(1) In the main interface, press V_Limit to switch the parameter focus to
"V_Limit".
(2) Enter a value by using the numeric keys, arrow keys, or the knob. For the
setting methods, refer to the descriptions of the built-in help information or
refer to the descriptions in "Parameter Setting Method".
Set C_Limit
The upper limit of the current working in CV mode. The default unit for C_Limit
is A, and it ranges from 0 A to 70 A.
(1) In the main interface, press C_Limit to switch the parameter focus to
"C_Limit".
(2) Enter a value by using the numeric keys, arrow keys, or the knob. For setting
methods, refer to the descriptions of the help information or refer to the
descriptions in "Parameter Setting Method".
4. Turn on the channel input
Press On/Off to turn on the channel input. At this time, the actual input
voltage, current, resistance, and power will be displayed in the main interface.
WARNING
To avoid electric shock, ensure that the DUT is connected to the
input terminals of the load properly before you turn on the channel
input.
CAUTION
When the fan stops working, the channel is disabled. Then, a
message is displayed, "Fan stops running!"
5. View waveform display
Press the waveform display key
to enter the waveform display interface,
as shown in Figure 2-7. When you select "U" under "Data", you can view the
voltage waveform. When changes occur to the current, the input voltage
remains to be the set voltage, unchanged. For detailed operations, refer to the
descriptions in "Waveform Display Function" section. Press the waveform
display key
again to exit the waveform display interface and return to the
main interface of CV mode.
