1.Read theseoperating instructionsthoroughlyand completelybefore
operating yourmeter.Payparticularattention toWARNINGSwhich
willinform youofpotentiallydangerousprocedures.The instructions
inthesewarningsmustbe followed.
2.Always inspectyourmeter,testleadsand accessoriesforanysignof
damage orabnormalitybeforeeveryuse.If anyabnormalconditions
exist(eg-broken testleads,cracked cases,displaynotreading,etc.),
do notattempttotakeanymeasurements.
3.Donotexposethe instrumenttodirectsun light, extremetempera-
tureormoisture.
4.Neverground yourselfwhen taking electricalmeasurements.Donot
touchexposed metalpipes,outlets,fixtures,etc., whichmightbe at
ground potential.Keep yourbodyisolated fromground byusing dry
clothing,rubbershoes,rubbermats,oranyapproved insulating ma-
terial.
5.Toavoidelectricshock useCAUTIONwhen working withvoltages
above40 Vdcor20 Vac.Suchvoltagesposeashock hazard.
6.Neverexceed the maximumallowableinputvalue ofanyfunctionwhen
taking ameasurement. Refertothe specificationsformaximumin-
puts.
7.Nevertouchexposed wiring,connectionsoranylivecircuitwhen at-
tempting totakemeasurements.
8.Donotattempttooperatethisinstrumentinan explosiveatmosphere
(i.e.inthe presenceofflammablegasesorfumes,vaporordust).
9.When testing forthe presenceofvoltage,makesurethe voltage func-
tionisoperating properlybyreading aknownvoltage inthatfunction
beforeassuming thatazeroreading indicatesano-voltage condition.
Always testyourmeterbeforeand aftertaking measurementson a
knownlivecircuit.
10.Calibration and repairofanyinstrumentshouldonlybe performed by
qualified and trained servicetechnicians.
11.Donotattemptcalibration orserviceunless trained and anotherper-
son capableofrendering firstaidand resuscitation ispresent.

HOWTOMAKEMEASUREMENTS
Beforemaking anymeasurementsread saftyprecautions.Always
examine the instrumentand accessoriesused withthe instrumentfor
damage,contamination (excessivedirt, grease,etc.)and defects.
Examine the testleadsforcracked orfrayed insulation and makesure
the lead plugsfitsnuglyintothe instrumentterminals.If anyabnormal
conditionsexist, do notattempttomakeanymeasurements.
VOLTAGEMEASUREMENTS
1.Turnoff powertothe deviceundertestand discharge all capacitors.
2.Plug the black testlead intothe COMinputjack on the meterand
conne connectthe testlead tiptoagrounded point(the reference
pointformeasurementofvoltage).
3.Selectthe desired ACvoltage range (V),orDC voltage range
(V).If the magnitude ofthe voltage tobe measured isunknown
always startwiththe highestrange.
WARNING
Toavoidpossibleelectricshock,instrumentdamage and /orequip-
mentdamage,do notattempttotakeanyvoltage measurementsifthe
voltage isabove1000Vdc/750Vac.1000Vdcand 750Vacarethe
maximumvoltagesthatthisinstrumentisdesigned tomeasure.The
"COM"terminalpotentialshouldnotexceed 500Vmeasured to
ground.
4.Plug the red testlead intothe VOLTinputjack on the meterand
connectthe circuitwhereavoltage measurementisrequired.Voltage
isalways measured inparallelacross atestpoint.
5.Turnon powerthe circuit/devicetobe measured and makethe volt-
age measurementredusethe range setting ifsettoo highuntil asat-
isfactoryreading isobtained.
6.Aftercomplating the measurement, turnoff powertothe circuit/de-
viceundertest,dischange all capacitorsand disconnectthe meter
testleads.
