Key points of selecting clamp Ammeter
Clamp Ammeter is also called clamp meter, and more are called hook meter in Taiwan. Clamp on Ammeter is a convenient test instrument (also called nondestructive measurement) that clamps the wire and detects the current without cutting off the circuit. Analog pointer multimeter and digital multimeter are used to cut off the circuit to detect the current, humidity sensor probe, regulator, pt100 thermal resistance sensor, all copper solenoid valve, cast aluminum heater, heating ring, and clamp type Ammeter is just clamped on the outer skin of the energized wire to detect the current. It is simple to operate and can detect large current without directly connecting the circuit.
Clamp type meters, multimeters, and insulation resistance meters all have two detection methods for analog digital multimeters and clamp type meters: needle type and digital type. The standard type has a detection range of around 2A to 200A or 400A for AC and DC, and there are also products that can detect high currents of 2000A; There are also leakage detection products that can detect small currents of several mA, as well as products that can detect the true RMS of non sinusoidal waves other than sinusoidal waves such as transformer power supplies and switch conversion power supplies.
Clamp Ammeter, 4 key points for model selection?
1: Detection object
Choose the model based on different detection objects, such as AC current, DC current, or leakage current;
2: Detectable * large conductor specifications
Cooperate with testing sites, with different specifications ranging from 21mm diameter to 53mm diameter;
3: Is it necessary to test the true efficacy value
Clamp Ammeter using average mode cannot correctly detect non sine wave circuits such as motors and transformer circuits. Clamp Ammeter using true RMS mode should be used to detect this circuit;
4: Other functions
The clamp Ammeter can not only detect the current, but also has the detection function and recording output in one model.
