OPERATION

Pleasemakesure thatyouhavealready readand fullyunderstand theWARNINGsectiononpage2.

4.1 Making Measurements with the FlexProbe®

1. ConnecttheelectronicmoduletotheACVoltrangeofyourDMMormeasuringinstrument.

2. Select the appropriate module output voltage range. If the currentmagnitudeisunknown,selectthe3000Arange.

3. Wraptheflexiblecorearoundtheconductortobetested.Selectthe300Arange toobtain thebest resolution, if the reading is less than300mV.

Do not exceed specified current range for the output. Do not use on selected range if Overload LED goes on.

4. Example:

a. ReadtheDMMdisplayedvalue:2.59V

b. DeterminetherangeandoutputusedontheFlexProbe:0.01V/Aforthe300Arange;.001V/Aforthe3000Arange

c. Dividethereadingbytheoutputtodeterminetheactualcurrentvalue:2.59÷0.01=259Aor2.59÷0.001=2590A

4.2 Tips for Making Precise Measurements

• When using the FlexProbe® with a meter, it isimportant to select the range that provides thebest resolution. Failure to do this may result inmeasurementerrors.

• For best results, select the highest FlexProbe® output signal possible and the most sensitivemeterrangeforthisoutput.

• MakesuretheDMMormeasuringinstrumentcanaccurately measure mVAC. Certain inexpensiveDMM have poor resolution and accuracy whenmeasuringlowmVAC.

• Forbestaccuracy,centertheFlexProbe®aroundtheconductortobemeasured.

• Toincreasethesensitivityormeasureonlowcur-rents, the FlexProbe® may be wrapped severaltimesaroundtheconductor.Remembertodivideyourreadingbythenumberofturnsfortheactualmeasurement(SeeFigure1).

• TheoverallmeasurementaccuracyisthesumoftheFlexProbe® accuracyandthedisplayinginstru-mentaccuracy.

• TheFlexProbe®maybedoubledaroundthecon-ductortobemeasuredtodoubletheoutput.(SeeFigures1and2toshowthedifferentvaluesonaDMMwhilemeasuring250AAC.)
