This symbol signifies that the instrument is protected by double or
reinforced insulation.
This symbol on the instrument indicates a WARNING and that the operator
must refer to the user manual for instructions before operating the
instrument. In this manual, the symbol preceding instructions indicates that
if the instructions are not followed, bodily injury, installation/sample and
product damage may result.
Risk of electric shock. The voltage at the parts marked with this symbol may
be dangerous.

OPERATION
4.1 Zero Adjustment
Theprobehasazeroadjustmentthatshouldbeadjustedbefore
measurement.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
oscilloscope.
•
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
disconnecting it from your meter or instrument.)
Youmayalsouseyouroscilloscopetoamplifythesignalwhileusingthe
100mV/Aproberange(whichoersthebestaccuracyandleastphase
shift).
NOTE: It is possible to change the range on the current probe without removing
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.

Ifnot,replacethe9Vbattery.
4.4 Peak Overload (OL) Indication (Red LED)
TheSL261oersanoverloadindicator.IftheredLEDilluminatesduring
measurement,thisindicatesthat thepeakvalueexceedstheinstrument
