1.1 International Electrical Symbols

This symbol signifies that the instrument is protected by double or rein-forced 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.This symbol refers to a type A current sensor. This symbol signifies that application around and removal from HAZARDOUS LIVE conductors is per-mitted.Probe fitted with an electronic output limiter providing protection against voltage surges caused by the accidental opening of the probe secondary circuit to 30V max. peak.

In conformity with WEEE 2002/96/EC.

1.2 Definition of Measurement Categories

CAT II: Formeasurements performed on circuits directly connected totheelectricaldistributionsystem.Examplesaremeasurementsonhouseholdappliancesorportabletools.

CAT III: For measurements performed in the building installation atthe distribution level such as on hardwired equipment in fixedinstallationandcircuitbreakers.

CAT IV: For measurements performed at the primary electrical supply(<1000V) such as on primary overcurrent protection devices,ripplecontrolunits,ormeters.

OPERATION

4.1 Zero AdjustmentTheprobehasazeroadjustmentthatshouldbeadjustedbeforemeasure-ment.Alternatively,youmay“zero”withtheoscilloscopeinstead.

4.2 Current Measurement

WARNING: Always connect the probe to the instrument before clamping onto the circuit under test.

• ConnecttheModelSL261totheproperinputchannelontheoscil-loscope.

• Beginwiththeleastsensitiverangeonthecurrentprobe(10mV/A)

• Selectthe0.5V/Divisionrangeontheoscilloscope.

• Clamptheprobeontheconductortobemeasuredandreadthecurrentflowingdirectlyonyouroscilloscope.

(Remember to unclamp the probe from the conductor before discon-necting it from your meter or instrument.)

Youmayalsouseyouroscilloscopetoamplifythesignalwhileusingthe100mV/Aprobe range (whichoffers thebestaccuracyand leastphaseshift).

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.
