FAQ

What type of gear is used in the caliper 22O line?

Clamp meter is used to measure the current card line, 220V line to exchange files, if you do not know how much current, first hit the high-end position, you take a photo of the best clamp meter decreased gradually to an appropriate position

How to measure low voltage line grounding with pliers

Clamp current meter range is large, generally used only for current measurement circuit, the zero sequence current can not accurately measure the line leakage current and three-phase circuit.

How much can the current clamp measure up to? How much accuracy can be achieved?

The measuring range of this caliper meter can be great, but the accuracy depends on the manufacturing process.I am in charge of the Japanese HIOKI, the largest range of 1000A, accuracy of 1.5%; this is already quite sophisticated in the industry.

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

The normal zero line with ground wire is not the zero line is tapped from the neutral point of transformer, wire from ground tap buried underground, but in actual use, line five wire three-phase voltage is 380 volts, the zero line and ground wire is not feasible, because there is a 220 volt single-phase equipment on the trip, will, 220 volts three-phase five wire circuit, because the zero line is rarely used, so the wiring, the zero line and ground line together.

How to auto discharge clamp current meter

Clamp ammeters referred to as clamp meter.The work is mainly composed of an electromagnetic current meter and bushing type current mutual inductor. Straight through current transformer core made of movable opening, and a clamp on ammeter, named. The utility model is a portable instrument which can directly measure the alternating current of the circuit without disconnecting the circuit, and is very convenient for use in the electrical overhaul, and is widely used.

How can the clamp meter measure current and measure overload current?

A gauge for measuring current and how to measure an overload current:1 will be moved to AC current clamp meter gear top position (maximum current clamp meter must be 1.25 times higher than the load current)2 each phase of the current is measured, the current in the rated range is its load current, more than the rated value, the current is its overload current.

Clamp meter cable direction? Why do I change the direction of measurement with a cable, the current is not the same

Clamp type ammeter, clamp wire, current measurement method can only measure alternating current, the battery should be charged dc.

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

The other is a direct current clamp type measurement table (see Figure three), general electrician or electronics repair shop has the current clamp type table, the table in the DC gear, the range of current selection must input current electronic fishing device is greater than the measured gear.
