CHAPTER 2
PRODUCT FEATURES
2.1 Description
TheFlexProbe®isaexibleACcurrenttransformercomposedofaexible
sensorandanelectronicmodule.The exiblesensorpermitsmeasure-
mentsonconductorswherestandardclamp-onprobescouldnotbeused.
In particular, it can be installed in tight spaces, around breaker panels,
aroundcablebundles,aroundwideorlargebusbars,orevenwrapped
aroundirregularshapes.
TheShapeMemoryfeatureenablestheuserto“pre-shape”thesensor
beforeinsertingitbetweenoraroundconductors.Thisfeaturefacilitates
closing,enhancesusersafety,andalleviatesthedroopingeffecttypically
associatedwithexiblesensors.
TheFlexProbe®islightweight.Itdoesnotusemagneticcoreslikestandard
transformers.Thetransformationprincipleisbasedonanaircore.Itpres-
entsvirtuallynoloadtothesystemundertest,hasalowphaseshiftand
excellentfrequencyresponse,andcannotbedamagedbyoverloads.
Thesensorassemblyiswaterproofandinsulatedfor1000VCATIII;600V
CATIV.TheFlexProbe®meetsEN61010-1andisCEmarked.
The FlexProbe® has a mV output proportional to the current measured
fordirectreadingsonDMMs,dataloggers,oscilloscopes,andpoweror
harmonicmeters.TRMSmeasurementsaretakenwhenconnectedtoa
TRMSmeter.TheFlexProbe®isinsensitivetoDCcurrentsandonlythe
ACcomponentofthemeasuredsignalismeasured.Thesensorlengthis
24".

OPERATION
Please make sure that you have already read and fully understand the
WARNINGsectiononpage2.
4.1 Making Measurements with the FlexProbe®
1. ConnecttheelectronicmoduletotheACVoltrangeofyourDMMor
measuringinstrument.
2. Select the appropriate module output voltage range. If the current
magnitudeisunknown,selectthe3000Arange.
3. Wraptheexiblecorearoundtheconductortobetested.Selectthe
300Arangetoobtainthe best resolution,ifthereading is lessthan
300mV.
Do not exceed specied current range for the output. Do not
use on selected range if Overload LED goes on.
4. Example:
a. ReadtheDMMdisplayedvalue:2.59V
b. DeterminetherangeandoutputusedontheFlexProbe:0.01V/A
forthe300Arange;.001V/Aforthe3000Arange
c. Dividethereadingbytheoutputtodeterminetheactualcurrent
value:2.59÷0.01=259Aor2.59÷0.001=2590A
Forbestaccuracy,carefullycentertheconductorinsidetheexiblecore,
andavoidifpossible,theproximityofotherconductorswhichmaycreate
noiseandinterference(particularlynearthelatch).
TrueRMSmeasurementsareobtainedwhentheFlexProbe®is connected
toaTrueRMSmeter.NotethattheDCcomponentisnotmeasured.

4.2 Tips for Making Precise Measurements
• When using the FlexProbe® with a meter, it is
important to select the range that provides the
best resolution. Failure to do this may result in
measurementerrors.
• For best results, select the highest FlexProbe®
output signal possible and the most sensitive
meterrangeforthisoutput.
• MakesuretheDMMormeasuringinstrumentcan
accurately measure mVAC. Certain inexpensive
DMM have poor resolution and accuracy when
measuringlowmVAC.
• Forbestaccuracy,centertheFlexProbe®around
theconductortobemeasured.
• Toincreasethesensitivityormeasureonlowcur-
rents, the FlexProbe® may be wrapped several
timesaroundtheconductor.Remembertodivide
yourreadingbythenumberofturnsfortheactual
measurement(SeeFigure1).
• Theoverallmeasurementaccuracyisthesumof
theFlexProbe® accuracyandthedisplayinginstru-
mentaccuracy.
• TheFlexProbe®maybedoubledaroundthecon-
ductortobemeasuredtodoubletheoutput.(See
Figures1and2toshowthedifferentvaluesona
DMMwhilemeasuring250AAC.)

MAINTENANCE
Warning
• Formaintenanceuseonlyspeciedreplacementparts.
• Toavoidelectricalshock,donotattempttoperformanyservicing
unlessyouarequaliedtodoso.
• Do not perform any service while the FlexProbe®is on any
circuit.
• Toavoidelectricalshockand/ordamagetotheinstrument,donot
getwaterorotherforeignagentsintotheelectronicmodule.
• Alsoseewarningonpage2.
5.1 Changing the Battery
IfthepowerONindicator(greenLED)blinksordoesnotlightup,replace
thebattery.
Disconnect the instrument from any source of electricity.
• To replace the battery, open rear case, replace battery and re-
assemble.
• ThegreenLEDshouldgoonwhenthemoduleisturnedon.
5.2 Cleaning
• Useasoftclothlightlydampenedwithsoapywater,thendrywith
