5.1.9 Usage of quick setting key. In the parameter setting interface, press the “VOL”, “I” and “TIME” keys to quickly enter the settings of voltage, current, and voltage test time respectively.
5.2 Related interfaces of test and instructions
After the parameter setting is completed, return to the interface of Figure 2, insert one end of the high-voltage test line into the high voltage output port, and clamp the sample at the other end; insert one end of the test line into the loop port, and clamp the other point of the sample on the other end. Press the start button to start the test, and the test indicator lights up. In the test, if the tested sample is not qualified, the tester sends out acousto-optic alarm signal, the buzzer rings, and the alarm lamp lights up, at this time, you must reset the tester by pressing the reset key. If the test of the sample is completed and the tested sample is qualified, the qualify indicator lights up.
Press any key to enter the last test mode when you start the tester at the next time, as the interface in Figure 28 shown, you can also press the mode key to select the pre-set test mode for testing.
5.2.1 Withstand voltage test: Figures 18 to 21 are the interfaces of withstand voltage test.
The table cell with shading in Figure 18 represents the boost time of the high voltage output.
The table cell with shading in Figure 19 represents the test time of the withstand voltage test.
The table cell with shading in Figure 20 represents the voltage value of the high voltage output.
The table cell with shading in Figure 21 represents the value of leakage current.

6 Safety operation regulation
Please read this paragraph carefully before using this instrument
(1) This instrument must be well grounded.
(2) The operator must be familiar with the usage of this instrument.
(3) Use a workbench made of non-conductive material. No metal shall be used between the operator and the object to be tested.
(4) In the course of the test, it is not allowed to touch the object being tested or any object connected to the object absolutely.
(5) During the testing process, it is not allowed to press the keys unrelated to measurement on the instrument panel at will.
(6) During continuous testing, the instrument must be reset to cut off the output if the wire between the instrument and the tested product is to be reconnected.
(7) If the instrument is found to be working abnormal, press the "reset" key or shut down to suspend the test and restart the test after recovery

Instrument sends test data:
Baud rate 9600 without check bit
01 Data head 0X55 10 Data tail 0xaa
02, 03, Working time 000.0 S - 999.5 S
04,05: Withstand voltage 00.00 kv - 20.00kv
06,07: Withstand current 0.000 ma - 5.000ma 05.00ma - 50.00ma
08: Status bit 08.1, 15.0 = 00 V withstand boost time 01 withstand voltage test
10 Waiting time 11 Insulation test time
08.7=0 set, wait state 08.7=1 Test status
08.6=0 insulation test normal 08.6=1 insulation alarm
08.5=0 withstand test normal 08.5=1 withstand voltage alarm
09: Gear 09.1, 09.0 = 00 first gear 01 second gear

The computer sends instruction and data format and the instrument sends back instruction and data format
The instrument sends back the data, when the instruction is sent back
01 data head 0x55 04 data tail 0xaa
02 Current working state of instrument
03 Instructions just sent
When the instrument sends back the data
01 data head 0x55 05 Data tail 0xaa
02 Current working state of instrument

Computer sends data:
01 data head 0x55 04 Data tail 0xaa
02,03 Set the data of items
Computer sends data: test time 0000-9995 (000.5 - 999.5 S)
Boost time 0001 - 0400 (0001-0400 S)
Interval 0000-0995 (000.5 - 099.5 S)
Withstand voltage 0050-0500 (00.50-05.00 kv)
Withstand current 0005 - 1000 ( 000.5-100.0 ma)
Computer sends instruction

After sending the "on-line" signal, wait for the instrument to return the data, to determine the model of the instrument and set the parameters
Send “Test” signal to start the instrument test, send “Test” again to start the next test after one test is completed, so cycle
Send “Reset” for instrument reset
Send data to set test current, alarm resistance, test time and other data
Send “Enter”, and the instrument saves the data transmitted by the computer
Send “Mode” to enable one of the four modes saved by the instrument
Indication of current working status of the instrument, state
