5. 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.
If the load passes the test, a prompt message is displayed, "OCP test passed!"
The DUT will automatically turn off output.
If the load fails the test, one of the following prompt messages is displayed:
"Upper limit exceeded. OCP test failed!" "Lower limit exceeded. OCP test failed!"
Or "Timeout! OCP test failed!" Then, the channel input of the load will be
automatically turned off.
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!"
6. View waveform display
After you enter the main interface, press the waveform display key
to
enter the waveform display interface, as shown in Figure 2-31. The current will
have a stepped increase. If the OCP test is successful, the current will increase
until it reaches the protection current of the DUT; if the OCP test fails, the
current will increase until it reaches the set maximum current. 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 OCP test function.

Tip
In the guide interface, you can only use the numeric keys to input the value for the
parameter; in the main interface, you can use the numeric keys, the arrow keys, or
the knob to input the value for the parameter.
