Instrument Installation and Preparation 1. Unpacking and inspection: After unpacking, please check if the instrument and accessories are complete and whether there is any damage during transportation. Please keep the packing box and packing materials for future use. 2. Installation: Place the instrument on a stable surface and connect the power supply to the instrument. The power supply voltage should be AC220V±10%, 50Hz±1Hz. 3. Connection: Connect the test leads to the instrument according to the wiring diagram. The red lead is connected to the positive pole, and the black lead is connected to the negative pole. IV. Operation Instructions 1. Power on: Turn on the power switch, the instrument will enter the initialization state, and the LCD screen will display the instrument model and version number. 2. Menu operation: The instrument adopts menu operation. Press the menu button to enter the menu interface, and then press the up and down buttons to select the corresponding function. Press the enter button to confirm the selection. 3. Voltage selection: Select the appropriate voltage according to the actual test requirements. Press the voltage button to select the voltage, and then press the enter button to confirm the selection. 4. Test range selection: The instrument can switch the test range automatically. When the test range is switched, the LCD screen will display the corresponding symbol. 5. Start testing: Press the start button to start testing. During the testing process, the LCD screen will display the test data and the testing time. If the test result exceeds the set limit, the instrument will automatically beep and display the alarm symbol. 6. Data storage: The instrument can save up to 60 groups of test data. Press the data button to enter the data storage interface, and then press the up and down buttons to select the corresponding data. Press the enter button to view the data. 7. Data communication: The instrument has RS232 serial interface, which can communicate with the computer data. 8. Power off: After the test is completed, turn off the power switch. The instrument will automatically discharge the high voltage and enter the standby state. V. Precautions 1. The test leads should be connected correctly, and the red lead should be connected to the positive pole, and the black lead should be connected to the negative pole. 2. During the testing process, do not touch the test leads or the tested object to avoid electric shock. 3. After the test is completed, turn off the power switch and wait for the high voltage to be discharged before disconnecting the test leads. 4. Do not use the instrument in a humid environment to avoid damage to the instrument. 5. Please read the instruction manual carefully before using the instrument.
