FAQ

Use clamp meter?

In order to improve the accuracy of measurement, the wire must be placed in the center of the jaw. A core not near the transformer and motor shell and other electrical components, so as to avoid the influence of external magnetic field.

How to use the clamp ammeters

Clamp meter before the measurement was estimated the size of the current, and then decide which one range. If unable to estimate, can be the first to use the maximum range and appropriate for small files, with accurate readings. Cannot be used to measure small current file current. In order to prevent damage to the clamp type table.

According to the three-phase current and voltage, the reactive power and power factor are calculated

The use of general instrument, including clamp meter, measuring a reactive power and power factor. There is no basis for calculation.

What is the connection between the distribution box and the bridge?

The ground wire is at least 4 square cord, 4 square wire rated operating current of about 30A, since it has been burned, indicating that the current has doubled, and the current duration is longer.

Why do you use a multimeter to measure the zero line and ground wire?

1, multimeter switch to the AC voltage range, should be so multimeter has such a function,2, range from 200mV~750V, the general 200V file, some clamp type table no 200V file can choose a bigger range, the pointer multimeter stalls to dots can choose 10 V ~100V 3, and then the probes were inserted in V /COM (Jack 220V voltage measuring everyday appliances)4, the black pen line around the left circle (see Figure 2-3) of course, the more the better, pay attention: this black pen needle do not touch hands, to prevent electric shock5, right hand with the red pen were measured in the zero line or line, you write down the results of the 2 measurements, the small FireWire, zero line.

Digital caliper table GT201, pliers table GT201 how to use?

The main function of the digital caliper meter GT201 is that it can conveniently measure the AC current value at work without having to connect any measuring lines

Which is the best way to export lj2085 and lj2025 fishing gear?

One is the direct series current measurement table (Figure 1), the input current fishing is motionless on the tens of amperes, reached 100 as Erdogan, the company's LJ-4025NP fishing device to maximum more than 200 amperes. Such a large current, the market generally does not have such a large ammeter, then it is necessary to use resistance sampling method to carry out sampling calculations

The difference between digital multimeter and caliper type multimeter

The principle of clamp meter is the use of electromagnetic induction principle, core wire clamp measurement will require the clamp meter of silicon steel lamination edges, then the wire clamp is equivalent to a coil current transformer, belonging to a current through the coil, when will dinner two coil clamp type ammeter inside induction two current, current in the wire clamp type ammeter dial can read the measurements.
