Use

1.2.1 When using, you must use the correct function and range.
1.2.2 Do not exceed the protection range of each range to measure the value.
1.2.3 Do not touch the top of the test leads (metal parts) when the meter is connected to the measuring circuit.
1.2.4 In the measurement, if the measured voltage is higher than 60V DC or 30V AC (RMS), should pay attention to keep the fingers always in the table after the finger care device.
1.2.5 Do not measure the voltage when the voltage between the measuring end and the earth exceeds AC 600V.
1.2.6 Before turning the change switch to change the measuring function, remove the test leads from the circuit under test.
1.2.7 Do not live measurement resistance, capacitance, diode and test circuit off.
1.2.8 In the current, resistance, capacitance, diode and line continuity test range, care should be taken to avoid connecting the meter to the voltage source.

3.2.1 True rms zero input

3.2.1.1 The measurement of sine wave signal, the use of true RMS measurement method than the traditional average response method error is small.

3.2.1.2 True RMS The instrument can accurately measure the sine wave signal, but if it is on the AC function, the instrument may display 1 to 50 if the measured signal is not input (shorted at the AC voltage range and the input terminal) Word between a reading. These deviations are normal. Within the specified measuring range, they do not affect the accuracy of the multimeter to measure alternating current.

3.2.1.3 True RMS requires that the input signal reach a certain level for measurement. Therefore, the AC voltage and current range is specified between 2% and 100% of full scale.
