II Introduction
Digitaldoubleclamp phase voltammeter isthe latestproductofourcompany's
clamp-typemeterseries.Itisa hand-held, dual-channel input all-digital,
multi-function, high-precision,intelligent multi-parameterfrequency
measurementinstrument.The instrument usesthe latestmicroprocessortechnology
and digital signal processingtechnology toachieve powerfrequencymeasurement
(suchas voltage,currentRMS,activepower, reactivepower,apparentpower,power
frequency,powerfactor,phase relationship, etc.),Determine thetransformer
wiring group,inductive,capacitivecircuit,testthesecondarycircuitand bus
differential protection system, read out thephaserelationship between the
differential protection CT groups, check the power meter wiring is correct or
not,themeteruses theclamp-typecurrenttransformer conversionmethod toinput
the measured current, so there isno needtodisconnectthecircuit undertest.

VIII Charging Battery：
The batteryisa6VNiMH batterypack. Whentheinstrumentpower supply
voltage islower than5.2V,thebatterysymbol isdisplayed,indicatingthatthebattery
power is insufficient. Pleasechargeitintime.
IX Other Explanationsand Considerations
1Currentclampspecificity
The twocurrentclampsofthemeterarededicated tothismeter and cannotbe
used for another meter,Atthe sametimethe order ofthetwoclampscannotbe
interchanged,otherwisetheerrorwill increase.Currentclamptopreventthe
impact,thejawplane must be keptclean,completelyclosed test isreliable.
2. Currentclamp maintenance
Afterthecurrentclampisused,thedustintheplaneofthejawsshouldbe
promptly removed.The planeofthejawsshouldnotbecleaned withroughobjects
or corrosion.Itisbesttouseasoftcloth(suchas:WD-40 lubrication) togently
