Extension elongation is 10mm；The various terminals of Power Secondary screen cabinet are adapted to, convenient for being operated on Power Secondary screen cabinet.
When test in the circuit that energization instrument accessed generate instantaneous high pressure, pass through transient high-current when, test in energization instrument
Two-way TVS Transient Suppression Diodes 9 occur avalanche breakdown, be supplied to one super-low resistance access of transient high-current, then instantaneously
Electric current is drawn away by two-way TVS Transient Suppression Diodes 9, so as to inhibit two poles with two-way TVS transient states to testing in energization instrument
The relay coil in parallel of pipe 9 plays a protective role, and avoids testing energization instrument and is burned；Meanwhile voltage returns to normal value it
Before be always maintained at blanking voltage.Electrical verification is connected in circuit to be tested when leading to tool work and is formed into a loop, and is disconnection in self-lock switch
During state, relay coil 8 must be electric, and relay contact 5 is closed, and 3V active buzzers 6 are linked into electrical verification and lead in instrument circuit.This
When, if circuit to be tested is not turned off, the light bulb that instrument is led in electrical verification sends light, and 3V active buzzers 6 send the sound；If

(2) the passive test for outputing circuit break-make
As shown in figure 3, two terminals for testing energization instrument are connected on the passive both ends for outputing circuit to be measured, since the circuit is
Parasitic loop, so the polarity that two terminals are connect does not require.If the passive circuit of outputing is closed communicating state, test logical
The light bulb of electric tool sends light, and 3V active buzzers send the sound；If the passive circuit of outputing is off, test logical
Electric tool does not have any action.
(3) test in low-resistance circuit
As shown in figure 4, testing the both ends that energization instrument is connected on low-resistance circuit, the polarity connect to two wire connection terminals will not
It asks.At this point, according to the difference of light bulb bright-dark degree, the different situations of the low-resistance loop resistance can be test out roughly：Work as circuit
After connecting completely, if light bulb is in highlighted state, may determine that the resistance value of the low-resistance loop resistance the Ω of 0 Ω~3 it
Between；If light bulb is than dark, in low bright state, then it may determine that the resistance value of the low-resistance loop resistance between the Ω of 3 Ω~10；
If light bulb extinguishes, the resistance value of the low-resistance loop resistance is more than 10 Ω at this time.
