High Precision LCD Digital Multimeter 2mA 233g Low Battery Display

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.

Specification:

It can automatically select the appropriate measurement parameters according to the characteristics of the component. Its measurement accuracy can reach 0.2%. It combines the convenience of a handheld instrument and good performance of a table-type one.

The operation is simple, and users can see the test frequency, parameters, and speed by pressing the corresponding key; it also has the recording mode to take readings; the convenient operation of open and short circuit correction function helps improve the measurement accuracy.
