It is rapid:
(1) switch A, switch B, switch C are placed in the state of "off"；
(2) blocking is removed, jack A, jack B, jack D, the external high-grade power meter of jack E are passed through；
(3) switch B, switch C are placed in the state of " closed ", complete the power meter with metering interface under current state
It checks；
(4) switch B, switch C are placed in the state of "off", high-grade power meter is removed, blocks blocking；
(5) switch A, switch B, switch C are placed in the state of " closed ", it should the power meter normal work with metering interface.
The method that the above-mentioned power meter with metering interface is measured in situ, it is characterised in that including following step
It is rapid:
(1) switch B, switch C are placed in the state of "off", switch A is placed in the state of " closed "；
(2) blocking is removed, by jack A, jack C, jack D, the external calibration power source jack E, completes that metering interface should be had
Power meter metering；
(3) calibration power source is removed, blocking is blocked；
(4) switch B, switch C are placed in the state of " closed ", it should the power meter normal work with metering interface.
The present invention devises five fixed end electric connectors and two switches on power watch shell, avoids dismounting inspection
It even disconnects ray examination to lead to the problem of, to realize On line inspection and metering in situ.Power meter with metering interface
The on-off of measurement route is realized by switch button, it can be in the case where instrument not be dismantled, by measuring the external standard of jack
The metering (inspection) of power source (high-grade power meter) completion power meter.Production can be improved on the premise of equipment safety is ensured
Benefit, table is easy to use, easy to operate.
