Fault phenomenon | Possible cause | Solution |
The console cannot be closed |
2.Over-voltage protection setting is too low or 0V; 3.The zero position of the voltage regulator is not closed | 1.Swap the two input power cables at will; 2.Re-set the overvoltage value; 3.Check the zero baffle and zero switch Can't find resonance point |
Can't seek resonance | 1.Is the wiring correct or secure 2.Whether the capacitance range of the test product is within the range of use of the device 3.Resonant circuit is not formed | 1.Recheck the wiring 2.Re-check the capacitance of the test object 3.Check whether the loop connection is correct and whether the loop ground wire is grounded at one point |
