FAQ

How to use the caliper and its working principle?

A part of the measuring ammeter million is determined by the current transformer and current measuring part composed of 000 table. The iron core of the mutual inductor is provided with a movable part and is connected with the handle. When the utility model is used, the movable iron core is opened by pressing the handle. The wires of the current to be measured are put into the jaw and the handle is closed to close the iron core. At this point, the current through the wire is equivalent to the transformer primary winding, the two winding will appear induction current, the size of the wire by the working current and winding coil ratio is determined. The ammeter is connected to both ends of the two winding, so that the current indicated by it is the current in the two winding, which is proportional to the current in the work. So will be good as the amount of current reflect a scale on the side of the wire when a current is passed, and the two winding connected to the ammeter pointer is in proportion to deflect, thus indicating the value of measured current.

How can the air outlet of the air conditioner in the air conditioner flow out?

Drainage pipe bad: because the drainpipe aging, relaxation or bend into wave shape, resulting in poor drainage. Check whether the current reaches the rated current indicated by the nameplate in the refrigeration operation. (not up to rated current may be refrigerant leak).

How to measure low voltage line grounding with pliers

Two lines, three lines or four lines at the same time through the current clamp meter is 0 normal without grounding. If there is an electric current indicating leakage, it is possible to ground.

How to maintain and maintain the communication and power room?

AC / DC clamp type meter. AC / DC clamp meter as the daily maintenance work is one of the essential test tool, mainly used to test the voltage, current, frequency and other related parameters, it has high resolution and precision testing and more testing function. At present, the maintenance personnel usually use the FLUKE of the United States F337 AC / DC Clamp Meter (RMS), and Silicon Valley communication production of SGT-11A and SGT-12B single and double jaw clamp type table, this kind of instrument with large diameter and small jaw electrical test resolution and high precision, accurate measurement, current flow the characteristics of. At the same time, the manual design of this kind of pliers is very suitable for the occasions with small space. Noise meter. The noise meter is mainly used to test the pulse component of rectifier equipment and DC converter output voltage, that is, noise voltage. At present, the noise meter in the market is mainly analog and digital. The analog noise meter is mainly JH5151 of state owned Jianhua instrument factory. Although it is larger and heavier, it has many testing indexes and high accuracy. Digital noise meter mainly has FZY-120 and FZY-120A, it has light and easy, portable, simple test, visual display and so on. At present, maintenance personnel can choose to use according to their favorite.

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

Clamp meter is the current transformer measurement is a valid value.

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

To zn76126 fourteen class teacher said, with a wire clamp meter card in power when there is no current. If there is no, it can be proved that the electric wire zoom is transient. If there is a current to turn off the power of the box one by one to see if the current is reduced, the circuit of this box will be excluded. Look at the wiring of other distribution boxes.

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

The clamp meter maximum gear 1000A. Resolution 0.1A; accuracy + 2.5%+5. For example, the uni-t.

Automatic water heater, electric tube how to see good or bad?

Multimeter measure its resistance, but also according to power comparison;
