OPERATION
4.1 Zero Adjustment
Theprobehasazeroadjustmentthatshouldbeadjustedbeforemeasure-
ment.Alternatively,youmay“zero”withtheoscilloscopeinstead.
4.2 Current Measurement
WARNING: Always connect the probe to the instrument before clamping onto
the circuit under test.
• ConnecttheModelSL261totheproperinputchannelontheoscil-
loscope.
• Beginwiththeleastsensitiverangeonthecurrentprobe(10mV/A)
• Selectthe0.5V/Divisionrangeontheoscilloscope.
• Clamptheprobeontheconductortobemeasuredandreadthe
currentowingdirectlyonyouroscilloscope.
(Remember to unclamp the probe from the conductor before discon-
necting it from your meter or instrument.)
Youmayalsouseyouroscilloscopetoamplifythesignalwhileusingthe
100mV/A probe range (which offers the best accuracy and least phase
shift).
NOTE: It is possible to change the range on the current probe without remov-
ing the probe from the current carrying conductor, but it is important to
remember not to exceed the permissible peak ratings of 1000mV peak or
2000mV peak to peak maximum. The peak ratings by range are: 10A peak
on the 100mV/A range, 100A peak on the 10mV/A range.

4.3 Battery Indication (Green LED)
TheprobehasabatteryconditionLED.Toensureproperreadingswith
yourcurrentprobe,besurethatthegreenLEDislitduringmeasurement.
Ifnot,replacethe9Vbattery.
4.4 Peak Overload (OL) Indication (Red LED)
TheSL261offersanoverloadindicator.IftheredLEDilluminatesduring
measurement,thisindicatesthatthepeakvalueexceedstheinstrument
responselevelandthattheoutputisdistorted.Switchtheprobetoahigher
rangeifpossible.

MAINTENANCE
5.1 Maintenance
WARNING
• Toensureoptimumperformance,itisimportanttokeeptheprobe
jawmatingsurfacescleanatalltimes.Failuretodosomayresult
inerrorinreadings.
• Formaintenanceuseonlyspeciedfactoryreplacementparts.
• Toavoidelectricalshock,donotattempttoperformanyservicing
unlessyouarequaliedtodoso.
• Toavoidelectricalshockand/ordamagetotheinstrument,donot
allowwaterorotherforeignsubstancesintothecase.
• Disconnecttheunitfromallcircuitsandtestcablesbeforeopen-
ingthecase.
5.2 Cleaning
• Tocleantheprobebody,useasoftclothdampenedinasolution
ofmilddetergentandwater.Tocleanthecore,openthejawand
cleantheexposed coresurfaceswithacottonswabdampened
with isopropyl alcohol (isopropanol) or ethyl alcohol (fotocol or
ethanol).Lubricatethejawsmatingsurfaceswithalightoil.
• Do not use chemicals containing benzine, benzene, toluene,
xylene,acetone,orsimilarsolvents.
• Donotimmersetheprobeinliquidsoruseabrasivecleaners.

5.3 Replacing the Batteries
CAUTION: Risk of electric shock. Disconnect all input(s) from the unit or
remove the probe from any conductor before opening the battery cover to
change the batteries.
Ifthe greenbattery indication LEDdoes notlight upwhen the probe is
turnedon,thebatterieswillneedtobereplaced.
Donotreplacethebatterywhileprobeisinuse.
Toreplacethebattery:
• Disconnecttheprobefromthecircuitandtheoscilloscope.
• Turntheprobe“OFF”.
• Unscrewthebatterycompartmentscrewandpulloutthebatterycom-
partmentcover.
• Replacethebatteryandputthecoverbackon.
