II Introduction
Digitaldoubleclamp phase voltammeter isthe latestproductofourcompany's
clamp-typemeterseries.Itisa hand-held, dual-channel input all-digital,
multi-function, high-precision measurement instrument.The instrument uses the
latest microprocessortechnology and digitalsignalprocessing technology to
achievepowerfrequency measurement(suchasvoltage, currentRMS, power
frequency, phase relationship, etc.), Determine the transformer wiring group,

XOther Explanationsand Considerations
1Currentclampspecificity
The twocurrentclampsofthemeterarededicated tothismeter and cannotbe
used for another meter.Currentclamptopreventtheimpact,the jawplane must
be kept clean,completelyclosedtest is reliable.
2. Currentclamp maintenance
Afterthecurrentclampisused,thedustintheplaneofthejawsshouldbe
promptly removed.The planeofthejawsshouldnotbecleaned withroughobjects
or corrosion.Itisbesttouseasoftcloth(suchas:WD-40 lubrication) togently
