5. NCV measurement;
The operation is as follows:
5-1. Press and hold the
“
NCV/LIVE
”
button; enter the EF measurement.
5-2. The front end of the meter has NCV test points. As long as the point is close to the AC voltage, the buzzer will emit different continuations
according to the different strength of the signal, and the LCD will also display according to the strength of the signal. Different number of segments.
5-3.Cycle to trigger "NCV/LIVE" key, enter live live live live wire measurement, display live character on LCD, close to live wire test point with a
red meter, and make reliable contact with the point, the black meter end is suspended, and does not contact any test point; if the test point is live wire, the
LCD will display OL, and the buzzer will send continuous sound.
6.Frequency measuremen
Input sensitivity: 1V rms; overload protection: 550V DC or AC peak (no more than 10 seconds)
Frequency measurement
1.trigger power key; switch to frequency measurement function;
2.The black test lead is negative, the red test lead is positive, and the test lead reliably touches the test point;
3 Measurement values will be displayed on the LCD.
Note:
1) When the input exceeds 10Vrms, it can be read, but the error may be larger;
2) In a noisy environment, it is best to use a shielded cable when measuring small signals;
