1)   Self inspection process

The controller automatically enters the load detection. If no load is detected, the prompt message "load not connected" in the status bar of Figure 6 indicates that the booster or capacitive test sample is not connected.

Figure 6 the controller indicates that the load is not connected

1)   Boosting process

After the self-test is successful, the instrument will automatically enter the boosting state, as shown in Figure 7, and the prompt message in the status bar is "boosting". At the same time, the timing began.

Figure 7 the controller indicates that the voltage is boosting

1)   Equal amplitude output

The controller will raise the voltage to the set value in several cycles, and the instrument will output the equal amplitude, as shown in Figure 8. The prompt message in the status bar is "equal amplitude output".

Figure 8 constant amplitude output of controller prompt

4)   Downtime

Figure 9 controller prompts to stop the test

When the timing reaches the set time, the instrument will stop automatically, as shown in Figure 9, and the prompt message in the status bar is "stop the test".

The instrument stops the high-voltage output and automatically discharges the test object, as shown in Figure 10. The prompt message in the status bar is "discharging".

Figure 10 the controller indicates that it is discharging

After the shutdown, as shown in Figure 11, the prompt message in the status bar is "test passed" and the data history is saved.

Note: during the test, if there is no abnormal voltage, no discharge or overcurrent protection, the test can be considered as passed.

Figure 11 controller prompt test passed

This instrument provides two shutdown modes:

★ timed shutdown: when the timing reaches the set time, the instrument will stop automatically.

★ manual shutdown: click the "shutdown" key to stop the machine. The two shutdown modes are normal shutdown.

★ there are also two kinds of abnormal shutdown: over-voltage protection shutdown and over-current protection shutdown.

★ overvoltage protection shutdown

In the process of test, when the output high pressure exceeds the set limit, the instrument will automatically cut off the output after starting and shutting down the command, and then execute the data history saving. After shutting down, as shown in Figure 12, the prompt message in the status bar is "over voltage protection" and execute the data history saving.

Fig. 12 controller prompts over voltage protection

★ over current protection shutdown

In the process of test, when the output current exceeds the set limit, the instrument will automatically cut off the output after starting and stopping the command, and then

execute the data history saving. After the shutdown, as shown in Figure 13, the prompt message in the status bar: "overcurrent protection" and execute the data history saving.

All the data instruments that have been shut down by timing, clicking the "stop" key, over-voltage protection and over-current protection will automatically save them as historical data. It can save up to 64 times of measured data, and the previous 64 times will be deleted automatically. Click the "view" key in Figure 3 to open the interface in Figure 13 to view the historical data of the latest 64 tests.
