I. SafetyPrecautionsAnd Procedures
Thankyou forbuying ourwireless highvoltage ratiotester. Inordertoavoid possible
electrical shockorpersonalinjury,pleasebesure:strictlyabide bythe safetyrules
and precautions listed inthismanual.
lCheckwhether theinstrumentisingood conditionbeforeuse,nobreakage,no
useofthebackcover beforecover,otherwisethereisadanger of electricshock
lUnder anycircumstances,usethisinstrumentshouldpayspecial attentionto
safety, especiallywhen measuringvoltage linesaboveAC100V andabove.
lIfthelinevoltage exceeds 600v, theinsulation rod must beconnectedtouse
lBecausehighvoltage linesare dangerous,operatorshavetobe trained strictly
and get relevant fromthecountry
lHigh pressureOperationAuthenticationcanbeusedtocarryoutField Testwith
thisinstrument
lItisstrictlyprohibited tousethisinstrumenttotestbareconductorsorbusbars
withvoltages exceeding 60kv.
lNotethestickersand symbolson thepanel andbackof thisinstrument
lDonotplaceandstore instrumentsfor long periodsoftimein hot,wet, dewy
places orunder direct sunlight
lWhenhighvoltage currentclampdisplayslowpower,pleasereplacebatteryin
