(2) blocking is removed, jack A, jack B, jack D, the external high-grade power meters 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 in current state
Under inspection；
(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 be with the normal work of power meter of metering interface
Make.
The method that the above-mentioned power meter with metering interface is measured in situ, it is characterised in that including following step
Suddenly：
(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 sources jack E, completing should be with metering
The metering of the power meter of interface；
(3) calibration power source is removed, blocking is blocked；
(4) switch B, switch C are placed in the state of " closed ", the power meter that should carry metering interface works normally.
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 break-make for measuring circuit is realized by switch button, it can be in the case where instrument not be dismantled, by measuring the external standard of jack
Power source (high-grade power meter) completes the metering (inspection) of power meter.Production can be improved under the premise of ensureing equipment safety
Benefit, table is easy to use, easy to operate.
