How to test the 30KVA capacitor
The capacitance is measured with a capacitor meter, and the charging and discharging test is carried out with a multimeter
Clamp ammeters on what hold is
Clamp current meter measurement is the current instantaneous value of current, press the HOLD button to keep you press the instantaneous value
30mA leakage breaker trip home is always with what method to find the leakage point, with clamp ammeters how?
Leakage indicator (a square small button, usually with the shell flush, leakage after the jump will be out), there is no indication? If not, the explanation is that the current in the circuit is too large. Should check from the direction of large load or short circuit; if there is leakage indication, check from the leakage.
But after 3 minutes on the machine, there is no electricity, what's the matter?
If you can't open the circuit check all the best hit the table of capacitance, resistance to clamp type table file, two probe and two terminal capacitor contact, began to pass, slowly not normal. The frequent capacitance of the switch is easily damaged by current. If there is no problem, it may be where the leakage of fluoride, or Freon is not enough. If the system does not leak, the difference is only fluoride, that is, fluoride will be OK, if the leak, then a little trouble
Why is the air compressor leakage gap will open?
Large current start-up is caused by tripping, proposed to replace the air after the test machine
How to detect electronic fishing gear?
The measured current is calculated for the fishing power, but the measurement of the maximum input current, to load a certain amount of fishing with, can bring high power light bulbs, or on the site with the sun, back type fishing device (such as SUSAN-735MP) with 500W solar lamp, solar lamp is two LJ-2025NP 1000W.
How does the 36V transformer change the starting power of the car?
With a 20 "2" tube, add a heat sink, just one end of the 2 pole to connect 24 volts one end, and then use a multimeter to measure positive and negative poles, and then connect it to the corresponding positive and negative poles of the battery
Vc3266l digital caliper table phase sequence measurement
DC voltage measurement(1) select the function switch according to the required test 2 0V / 600V files. If you don't know the measured value, please select 600V for measurement.(2) the black pen plug ACOM jack, the red pen inserted V / Jack.(3) the test pen is connected to the power supply or load test.(4) the LCD display values of the measured voltage value, the red pen is connected with one end.(5) if LCD display "1" is connected with one end of the red pen is negative,
