Resistance.
Referring to Fig. 2, during verification relay, first relay is inserted on relay base, switching handle QK1 is switched to resistance
Shelves, switching handle QK2 is switched to normally closed contact shelves, and megameter registration is exactly relay-coil resistance, and low ohmmeter registration is exactly normally closed
The contact resistance of contact；Slide wire resistance is transferred to maximum resistance, switching handle QK1 is switched to voltage gear, switching handle QK2 is cut
To normal opened contact shelves, close a switch F1（10A air switch）, voltmeter registration is exactly relay both end voltage, adjustment slide wire resistance order
Voltage during relay excitation is exactly the startup voltage of relay, now, and low ohmmeter registration is exactly relay normally open contact closure
When contact resistance；Adjustment slide wire resistance makes the return voltage that voltage during relay loss of excitation is exactly relay.
It should be noted item：Switching handle QK1 is switched to before voltage gear and relay must be inserted on relay base；Verification
F1 must will be switched after a complete relay（10A air switch）Pull open or slide wire resistance is turned up full blast resistance value.
The above described is only a preferred embodiment of the present invention, any type of limitation is not done to the present invention, it is any
Without departing from the content of technical solution of the present invention, the technical spirit according to the present invention any is simply repaiied to made for any of the above embodiments
Change, equivalent variations and modification, belong to the scope of technical solution of the present invention.
