in the circuit to measure voltage ANotes Awarnings Do not input voltage over 1000Vrms It is possible to measure higher voltage However it may cause damage to the meter Be cautious to avoid electric shock when measuring high voltage ANotes Before using the device it is suggested to measure a known voltage for verification The meter input impedance is about 10MO This load may cause measurement error when measuring the high impedance circuit In most cases if the circuit impedance is under 10kQ the error can be ignored 00 1 The input impedance of DC mV scale is infinite 1000MQ and it does not attenuate when measuring weak signals so the measurement accuracy is high However when the test leads are disconnected there may be a value on the screen which is normal and will not affect the measurement result Readings of AC measurement are true RMS At AC voltage position short press 2s SEL REL button to enter frequency measurement Frequency measurement range 45Hz 1kHz for reference Min measurement amplitude 10 of voltage range If the measured capacitor is short circuited or the capacitance exceeds the maximum range the OL symbol will appear on the screen When measuring large volume capacitors it may take a few seconds to obtain steady readings When there is no input the meter displays a fixed value intrinsic capacitance For small capacitance measurement this fixed value must be subtracted from the measured value to ensure measurement accuracy Or users can choose the relative measurement function REL to automatically subtract the intrinsic capacitance 9 6 AC DC Current

measuring low resistance the test leads will produce 0 10 0 30 measurement error To obtain accurate measurement short circuit the test leads and use the REL function If the resistance is greater than 0 5O when the test leads are shorted please check if the test leads are loose or damaged When measuring high resistance at 60MO range it is normal to take a few seconds to steady the readings The internal 630mA and 20A fuses can be checked by the 6MO measurement function Please refer to Picture 5b for more details Insert the red probe to the 630mA or 20A input terminal to measure the resistance If both fuses are blown the OL symbol will appear on the screen Picture 2b If the measured resistor is open or the resistance exceeds the maximum range the OL symbol will be displayed on the screen Before measuring the on line resistance switch off the power supply of the circuit and fully discharge all capacitors To prevent possible electric shock fire or personal injury switch off the power supply of the circuit before measuring the current and then connect the meter with the circuit in series Please choose the correct input terminal and function to measure If the range of the measured current is unknown select the maximum range and then accordingly reduce There are fuses inside the 20A and mA pA terminals Do not connect the test leads with any circuit in parallel to avoid damage to the meter and personal injury ANotes Readings of AC measurement are true RMS If the tested current is 6A 10A the max measurement time should not exceed 60 seconds and the next test should be after 1 minute If the tested current is 10A the max measurement time should not exceed 10 seconds and the next test should be after 15 minutes When measuring AC current short press 2S SEL REL button
