FAQ

Try to explain in detail by combining pictures and words, thank you
Current clamp meter only measuring one conductor, the measured wire clamp should be placed in the center of the window, the window with all phase conductors can not measure.
What kind of appliances are these? What role does it play? Not how the measured current clamp meter?
12 is a 220V with air leakage protection switch, right?. The 3 is a 380V air switch. Play the role of power on or off.
What instrument can be used to detect high power?
If you use it regularly, he can find your location unless you hide it somewhere else, unlike the wires in your room.
How to use the 266CLAMPMETER clamp multimeter
The wrench jaw will open, the prediction of the amount of wire in the middle, measurement, the measured wire should be placed in the middle of the jaw with jaw, face such as noise, should be re opening and closing time, still have the noise, should handle the joint surface, in order to make accurate readings. In addition, not at the same time around the two wires.
How to use the multimeter to check the grounding wire is normal?
The bridge method has high accuracy, but it needs to be separated from the ground wire. It is necessary to insert a ground pile every 20 meters and 40 meters. It takes more than ten minutes to test a point.
Is there a caliper meter that can measure direct current?
Magnetic balance type current sensor called compensation sensor, namely the primary current Ip generated in the magnetic core premises through a secondary magnetic field coil current magnetic field generated by the compensation, the compensation current of Is accurately reflect the current of primary side Ip, so that the Holzer device is in the working state of zero magnetic flux detection.
I would like to ask the relationship between the power of the water pump motor and the flow of water
As long as the motor eats, it doesn't matter. You test it with a caliper watch. The current is not over loaded
Emerson DC panel
The current imbalance, see the information monitoring module, 1.3A module and current, and the clamp type table card under the battery load current, see Holzer 's are not allowed, no output voltage clamp meter, Holzer scale to see how much is MV, can be converted into the hypothesis correctly, that the question in the module I guess, you have a floating voltage module, the fault code E31
