When measuring voltage, do not input a limit voltage exceeding the effective value of 1000V DC or 750V AC. 2. Voltages below 36V are considered safe. When measuring voltages greater than 36V DC and 25V AC, ensure test leads have reliable contact, are correctly connected, and are well-insulated to prevent electric shock. 3. When changing functions and ranges, test leads must be removed from the test point.
