5. Measurement operation 5-1 DC & AC voltage measurement Warning: To avoid harms to you or damage to the meter from electric shock. Please do not attempt to measure voltage higher than DC/AC 1000V although readings may be obtained. The DC voltage range are 200.0mV, 2.000V, 20.00V , 200.0V and 600V and then. The AC voltage ranges are 2.000V, 20.00V, 200.0V and 600V. To measure DC or AC voltage: ① Insert the red test lead into the “VΩ” input terminal and the black test lead into the COM terminal.
PAGE 11
Note: ● The test lead can add 0.1Ω to 0.2Ω of error to resistance measurement. To obtain precision reading in low-resistance measurement, that is the range of 200.0Ω, short the input terminal before measuring. In this time, the contact resistance displayed on the LCD. You can subtract the contact resistance value from the measured value. ● For high-resistance measurement (>10MΩ), it is normal taking several second to obtain stable reading.
PAGE 12
● If diode is shorted, the display shows 0 (zero) in both direction. ● If display shows “OL” in both direction, the diode is open. 5.3.2. Continuity Check: ① Press the “FUNC” key to enter to the continuity mode. ② The buzzer sound if the resistance of a circuit under test is less than 100 Ω. 5-4. Frequency measurement ① Set the rotary switch to “Hz” position. ② Insert the red test lead into the “ VΩHz” input terminal and the black test lead into the “COM” terminal.
PAGE 13
Note: ● For safety’s sake, the measuring time for high current should be ≤10 second for each measurement and the interval time between two measurement should be greater than 5 minutes. ● When current measurement has been completed, disconnect the connection between the testing lead and the circuit under test. 5-7.

and input socket. ③Use the test pen on both ends of the other measuring capacitance of the capacitor under test value and measured value read from the LCD display. ④When the meter measuring large capacitance, it takes time to stable reading. 6. Maintenance 6-1. Replacing the battery When meter display the battery must be replace to maintain normal operation. ① Disconnect and remove all test probes from any live source and meter. ② Open the battery cover on the bottom case by screwdriver.
