Embodiment
As shown in Figure 1; A kind of multifunctional electric meter test board; The power supply that is connected with each circuit; It is characterized in that; Described test board send terminal row 4, toggle switch 5, switching value input, the sub-row 6 in relay control output end to form by power circuit 1, signal source circuit 2, signal source lead-out terminal row 3, direct current change, and described power circuit 1 is connected with switching value input, the sub-row 6 in relay control output end through toggle switch 5, and described signal source circuit (2) send terminal row (4) and signal source lead-out terminal row (3) to be connected with the direct current change respectively.
Be embodiment with test DMX300F series instrument below;
The AC power CS of instrumentation operation station is mainly used in control AC power input (AC220V), AC200V is provided power supply for the Meter Test platform.When the AC power CS was closed, the switch pilot lamp was bright, and the power supply input is arranged this moment.
Power circuit 1, mainly the AC signal with input becomes direct current signal.Wherein the input voltage ratings is 220V, allows ± 20% float, and the voltage signal of output is 24V/1.0A.Power circuit 1 output ± the 24V power supply is used for the test of leaving of instrument.
Switching value input, relay control output end son row 6 link to each other with corresponding terminal on the DMX300F series instrument.+ 24V, DI1, DI2, DI3, DI4 are the switching value input port; D01+, D01-, D02+, D02-are relay control output end mouth; A, B are PORT COM.
