FAQ

Use clamp meter?

The use of AC clamp meter measurement before estimating the measured current size, to select the appropriate range. If the magnitude of the current to be measured cannot be estimated, the maximum range of one gear shall be used for rough measurement, and then the appropriate range shall be changed according to the actual current to make more accurate measurements

What is the difference between the clamp meter and the universal table?

The clamp type meter measures very large current, and the multimeter can measure small current, and the caliper type meter doesn't need to be broken when measuring.

How to measure a zero line with a universal watch?

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 shock

What is the cause of the tripping of the two phase motor?

Leakage of electricity, turn on the motor - coil some varnish, and then dry, will solve the problem. If you do not have this process, let the maintenance master help you solve.

How does the multimeter measure Ann?

General multimeter can only measure 500 mA, type 500 multimeter, maximum measurement of 5 ann.

With the operation of the motor current clamp meter measuring three-phase, single-phase current is very low, what is the reason?

Place the line in the middle of the mouth and vertical to the mouth level;

Automatic tripping of circuit breaker often, this is why, what to do?

After analyzing the two causes of circuit breaker tripping, some common analysis and treatment methods are summarized. The first is to judge whether it is a circuit problem or a circuit breaker problem. The general process is:Observe whether the burning of a circuit, whether there is odor, the low voltage cabinet within the two control loop whether there is no fault1., when there is a fault point, the switch can be closed, the line problem is explained, and the circuit breaker is irrelevant.2. there is no obvious fault point, in the case of no load, the circuit breaker still can not switch on, it shows that the circuit breaker can not be put into operation, it is the problem of the circuit breaker itself.

What's the caliper watch for?

Measuring alternating current, the range is very large, generally can be measured thousands of ANN current, and the principle of the same current transformer. It also has the auxiliary functions of measuring voltage and resistance.
