. Safetyrules and precautions
Thankyou for purchasingthe company'shigh andlow voltage
clampammeter.Toavoidpossibleelectricshockorpersonalinjury,
please be suretostrictlyobservethe safetyrules andprecautions
listedinthismanual.
●Beforeuse, checkwhether the instrument isingoodcondition,
no damage,and forbidtouse beforethe backcoveriscovered.
Otherwise, thereisdanger ofelectricshock.
●Inanycase, it shouldpayspecialattentiontosafetyinuse of
thismeter, particularlyinmeasurement ofcircuitrywithmore
than AC100Vand abovevoltages.
●Ifthe voltage oftestedcircuitryhas exceeded 600V, itmust
be usedbyconnecting withan insulationrod.
●Asit isverydangerous ofhighvoltage transmission line, the
operatormust get strict training andthe relevant certification
on high-pressureoperationofthe statebeforeusingthismeter
and makingafieldtest.
●It isstrictlyforbidden tousethismeter totest the wirewithout
anyinsulateprotection orconvergence generatrix.
●Please payattention tomarked words and symbolson panel
or backboardofthismeter.
●Please donot put or storethismeter inthe placeofhigh
temperature,withmoisture,withfrozen deworwithdirect
daylight irradiationfor along time.
●Please notethe batterypolaritywhen replacing battery, and
removethe batteryifyouexpectnottouse thismeterfora
longtime.
●It must be operated byqualified staffthat has the authorization
on tearingdownor repairing thismeter.
●Checkthe housing beforeusingthe meter. Checkforcracks or

4
missing plasticparts.Ifthe head and otherpartsofthe
instrument aredamaged,please do not use it..
●Toavoidthe impact oftransducer clamp, it needs tomaintain
thismeterregularly.Donotuse corrosiveorcoarsematerials
toclean,butuse soft cloth(such as glasses cloth), dipa
lubricantthatisrust-proofand dehumidified,and gentlywipe
the meter.
●For the reason ofthismeter, incase that anydanger may
occur ifcontinue touse it, stop using it immediatelyand sealit
up forkeepingatonce,which shall be dealtwithby qualified
authorization agency.
●The danger symbol on the meter and the manual, the
usermustmake safeoperation accordingtothe indication.
●The extremelydangeroussymbol ”on the meterand the
manual,the usermustmakesafeoperationaccordingtothe
indication.
●It suggeststhat thismetershallbe made insulationintensity
testatleastonceeveryyear(AC 60kV/rms fiveinsulation rods
between the twoends.)
●The manualhas awirelesstransmissiondatatype.
. BriefIntroduction
The H/LVoltageClampMeterisahigh-voltagemeasurement
toolcomposedofaspecialclampammeterequipped withahigh
voltage insulation rod.Inside the clampammeter,amask
integratedcircuitisused,and an insulatingrod isconnected to
measurethe currentofahighvoltageline withabarewireorless
than 35 kV.When notusing the insulationrod,itcanalso beused
as ahigh-precisionlow-voltageclampammeter,leakagecurrent
meter,canaccuratelymeasurethe currentof0.1mA.It has a
simpletouse, easytocarry
Itswireless transmissiontestdata,equippedwithawireless
receiver,can receivemeasured datawithin30 metersofastraight
line(withoutobstacles), ensuring high-precision,highreliability,

5
and high stabilitythroughout the year..
The H/LVoltage ClampMeteralsohas functions such as peak
hold,dataretention,datastorage,wireless transmission,etc.Its
specialclampammeter canfacilitateclamping or evacuation ofthe
measured wirebypushingorretracting theinsulation rod,saving
timeand fast.
It can be widelyused insubstations,powerplants,industrial
and miningenterprises andtesting stations,electricalmaintenance
departmentsforcurrentdetection andfieldelectricalwork.
Insulation rodsarelight, moisture-proof,high-temperatureresistant,
impact-resistant, bend-resistant, and highlyinsulating.
