3 In 1 AC DC Digital Volt Ohm Meter HFE NVC Capacitor Meter Tester

AC/DC Ammeter Voltmeter Ohm Voltage Meter HFE NVC Capacitance Tester

Non - contact voltage measurement(NCV)

The function range switch is set to NCV range position. At this time, the instrument displays "NCV" and "EF" symbol, and the top of the instrument is close to the object to be tested such as mains, power switch, socket and so on. When the detected voltage is greater than 110V (AC RMS), the instrument NCV indicator will be lit and the buzzer will sound an alarm.

Technical indicators

Ambient temperature: 23 ± 5 ℃ Relative humidity: <75%
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.



3.2.2 DC voltage

- Input impedance: 10MΩ
- Maximum input voltage: 600V DC or 600V AC (rms)
Note:
In the small voltage range, the pen is not connected to the circuit under test, the instrument may have beating the reading,
This is normal, this is because the instrument caused by high sensitivity, does not affect the actual measurement results.


3.2.3 AC voltage

- Input impedance: 10MΩ

- Maximum input voltage: 600V AC (RMS) or 600V DC

- Frequency range: 40 ~ 1000Hz True RMS

Note:
In the small voltage range, the pen is not connected to the circuit under test, the instrument may have beating the reading,
This is normal, this is because the instrument caused by high sensitivity, does not affect the actual measurement results.



3.2.4 Alternating current

- Overload protection: mA range fuse (self-recovery fuse 200mA / 250V)
10A range without insurance
- Maximum input current: mA: 600mA DC or AC rms;
10A: 10A DC or AC rms;
When the measured current is greater than 5A, the continuous measurement time is not longer than 15 seconds, after the measurement to stop the current measurement for more than 1 minute.
- Frequency response: 40Hz ~ 1000Hz True RMS.

3.2.5 DC

- Overload protection: mA range fuse (self-recovery fuse 200mA / 250V)
10A range without insurance
- Maximum input current: mA: 600mA DC or AC rms;
10A: 10A DC or AC rms;
When the measured current is greater than 5A, the continuous measurement time is not longer than 15 seconds, after the measurement to stop the current measurement for more than 1 minute.


3.2.6 Frequency

- Overload protection: 250V DC or AC (rms)
- Input voltage range: 600mV ~ 10V AC (with the measured frequency increases, the input voltage should also increase)


3.2.7 Duty cycle

- Frequency response: 10 ~ 10MHz

- Input voltage range: 600mV ~ 10VAC (with the measured frequency increases, the input voltage should also increase)

- Maximum input voltage: 250V AC (rms)

Resistance

- Open circuit voltage: approx. 1.0V
- Overload protection: 250V DC or AC (rms)

Transistor test
