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.

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.

CURRENTMEASUREMENTS
WARNING
TheseSnap-Aroundsaredesigned totakecurrentmeasurements
on circuitswithamaximumvoltage differenceof500VACbetween
anyconductorand ground potential.Using the Snap-Around for
currentmeasurementson circuitsabovethisvoltage maycause
electricshock,instrumentdamage and/ordamage tothe equipment
undertest. Beforemeasuring currentmakecertainthatthe test
leadsareremoved fromthe instrument.
The Snap-Around isoverload protected up to500VACforup to1
min.Donottakecurrentreadingson circuitswherethe maximum
currentpotentialisnotknown.Donotexceed the maximumcurrent
thatthisinstrumentisdesigned tomeasure.
1.SetFunction SwitchtoACA/DCA1500ARange.
2.Press the triggertoopenthe transformerjawsand clampthemaround
aconductor.Jawsshouldbe completelyclosed beforetaking a
reading.
3.The mostaccuratereading will be obtained bykeeping the conductor
across centerofthe transformerjaws.
4.The reading willbe indicated on the display.
5.Reducethe range setting ifsettoo high until asatisfactorybest
resolution reading isobtained.
RESISTANCEMEASUREMENTS
WARNING
Attempting resistanceorcontinuitymeasurementson livecircuits
can causeelectricalshock,damage tothe instrumentand damage
tothe equipmentundertest. Resistancemeasurementsmustbe
made on de-energized (DEAD)circuitsonlyformaximumpersonal
safety.The electronicoverload protection installed inthisinstrument
will reducethe possibilityofdamage tothe instrumentbutnotneces-
sarilyavoidall damage orshock hazard.

2608.p65 ?2005/5/26, 下午 03:4911

1.Turnoff anypowertothe resistortobe measured.Discharge anyca-
pacitors.Anyvoltage presentduring aresistancemeasurementwill
causeinaccuratereadingsand coulddamage the meterifexceeding
the overload protectionof500VDC orAC.
2. Insertthe BLACKand REDtestleadsintothe COMand Ωinputtermi-
nalsrespectively.
3.Selectthe (Ω )positionbyturning the rotaryselectorswitch.
4.Connectthe BLACKand REDtestprobe tipstothe circuitordevice
undertest, making sureitisde-energised first.
5. Opencircuitswill be displayed asan overload condition.
6.The resistanceinthe testleadscandiminishaccuracy on the lowest
(400Ω)range.The errorisusually0.1to0.2Ωforastandardpairoftest
leads.Todetermine the error,shortthe testleadstogetherand then
usethe (ZERO)Relativemode toautomaticallysubtractthe lead re-
sistancefromresistancemeasurements.
7.Aftercompleting the measurement, disconnectthe DCMtestleads.
10
CONTINUITYTESTING
1.Selectthe ()positionbyturning the rotaryselectorswitch.
2.Followsteps2and 4asforresistancemeasurements.
3.Anaudibletone willsound forresistanceless than approximately40Ω.
Afterall measurementsarecompleted,disconnectthe testleadsfrom
the circuitand fromthe DCMinputterminals.
CAUTION
Measurementsmustonlybe made withthe circuitpowerOFF.
DIODETESTING
1.Setthe ()position byturning the rotaryswitch.
2.Followsteps2and 4asforresistancemeasurements.
2608.p65 ?2005/5/26, 下午 03:4912

3.The REDlead shouldbe connected tothe anode and the BLACKlead
tothe cathode.Forasilicondiode,the typicalforwardvoltage should
be about0.6Vsilicon diode or0.3Vforgermaniumdiode.
4. If the diode isreversebiased orthereisan opencircuitthe reading
displayed will be between 3.000Vand 3.400V.
CAPACITANCEMEASUREMENT
FREQUENCYMEASUREMENTS
1.Setthe rotaryselectorswitchtothe (Hz)position.
2.Plug the BLACKand REDtestleadsintothe "COM"and "Hz"input
terminalsrespectively.
3.Applythe testprobestothe pointsacross whichthe frequency isto
be measured,and read the resultdirectlyfromthe display.
NOTE:Forfrequenciesbelow100Hzand greaterthan 100KHz,the
displaymaynotbe stable.Forfrequenciesbelow1Hz,the displayshows
00.00Hz.
1.Turnoff powertothe deviceundertestand discharge allcapacitors.
2.Discharge all voltage fromthe capacitorbeforemeasuring itscapaci-
tancevalue.
NOTE:Asafewaytodischarge acapacitoristoconnecta100kΩ
resistoracross the twocapacitorleads.
3.Setthe rotaryselectorswitchtothe ()range.
4.Plug the BLACKand REDtestleadsintothe COMand Finputtermi-
nalsrespectively.
5.Touchthe probestothe capacitor.Always observepolaritymakings
when measuring pobrized capacitors.
6.The measurementaccuracy ofcapacitorscan be improved byfirst
using the "ZERO"(Relativemode)tozerothe displayand automatically
subtractthe residulmeterand testlead capacitance.Sincethe Relative
mode alsoselectsmanualranging,
7.Residualvoltage chargeson the capacitor,orcapacitorswithpoor
insulationresistanceorpoordielectricabsorption maycausemeasure-
menterrors.
8.Aftercompleting the measurement,disconectthe DCMtestleads.
