Referring to fig. 1, the present invention provides a detector for a multifunctional meter installation circuit, including: the device comprises a digital ammeter 1, a power module 2, a display module 3, an interface module 4 and a detection tool;

The interface module 4 comprises a voltage interface unit 401 and a current interface unit 402, and the voltage interface unit 401 is connected with the display module 3; the sockets of the current interface unit 402 are divided into three groups, each group is connected with a reset button 403, and the other end of the reset button 403 is connected with the input interface of the digital ammeter 1.
The detection tool comprises a meter pen and a strong magnet, and during testing, the connector of the meter pen is inserted into the fifth socket of the voltage interface unit 401. The end of the strong magnet with the red mark is an N pole.
Referring to fig. 1, the multifunctional watch to be tested is connected to phase a, phase B, phase C and phase N, respectively; the multifunctional watch to be detected is also connected with the phase A current transformer, the phase B current transformer and the phase C current transformer. The interface module 4 is sequentially matched with the socket of the multifunctional watch to be detected.
During testing, the wiring plug of the multifunctional meter to be detected is pulled down and inserted into the socket of the detector in sequence, so that whether the wiring of the multifunctional meter is correct or not can be detected.
When the reset button S1 is pressed, the N pole of the strong magnet is quickly brought close to or inserted into the threading hole of the current transformer L1 of the a phase, and the digital ammeter 1 instantly reads a positive current value. When the strong magnet is quickly removed from the threading hole of the A-phase current transformer L1, the digital ammeter 1 can instantly read out a negative current value, namely, the A-phase current transformer is correctly installed. If the ammeter has no reading or the sequence of the positive and negative values of the reading is inconsistent with the above situation, the wiring is in error.
The reset button S2 is pressed to make the N pole of the strong magnet quickly approach or insert into the threading hole of the B-phase current transformer L2, and the ammeter can also read a positive current value instantly. When the strong magnet is quickly removed from the threading hole of the B-phase current transformer L2, the ammeter can instantly read a negative current value, which indicates that the installation of the B-phase current transformer is correct.

When the strong magnet is quickly removed from the threading hole of the C-phase current transformer L3, the ammeter can instantly read a negative current value, which indicates that the installation of the C-phase current transformer is correct. If the ammeter does not read at the moment or the sequence of the positive and negative numerical values of the readings is inconsistent with the above situation, the connection of the C-phase current transformer is in error.
The connector of the meter pen is inserted into the fifth socket of the voltage interface unit 401, so that whether the connection of the phase a, the phase B, the phase C and the phase N of the power supply is correct or not can be detected.
When the stylus pen is touched to the first socket of the voltage interface unit 401, the corresponding indicator light LED1 will be turned on, and if the indicator light LED1 is not turned on, or if the indicator light of the corresponding phase is not turned on, it indicates that the wiring is wrong.
Similarly, when the stylus pen is touched to the second socket, the third socket and the fourth socket of the voltage interface unit 401, the corresponding indicator light LED2, indicator light LED3 and indicator light LED4 will be lighted, and if the corresponding indicator light is not lighted, or if the indicator light of the corresponding phase is not lighted, a wiring error is indicated.
