WarningThe current probe may only be used and handled by qualifiedpersonnel. To avoid personal injury, follow these precautions:– To avoid electric shock, use caution during installation and use of thisproduct; high voltages and currents may be present in circuit undertest.– Do not use the product if damaged. Always connect probe to displaydevice before it is installed around the conductor.– Always ensure the probe is removed from any live electric circuit, andleads are disconnected before removing the battery cover.– Use the Current Probe only as specified in the operating instructions;otherwise the current probe’s safety features may not protect you.– Adhere to local and national safety codes. Individual protective equipment must be used to prevent the shock and arc blast injury wherehazardous live conductors are exposed.– Do not hold the Current Probe anywhere beyond the tactile indicator.– Before each use, inspect the Current Probe. Look for cracks or missingportions of the Current Probe housing or output cable insulation. Alsolook for loose or weakened components. Pay particular attention tothe insulation surrounding the jaws.– Use caution when working with voltages above 60 VDC,30 VAC rms or 42 VAC peak. Such voltages pose a shock hazard.– Use of this equipment in a manner not specified herein may impairthe protection provided by the equipment.– CAT III equipment is designed to protect against the transients in theequipment in fixed equipment installations, such as distribution panels, feeders and short branch circuits, and the lighting systems inlarge buildings.Always inspect the probe and lead for damage before use.To avoid electric shock, keep the probe clean and free ofsurface contamination.Safety in its use is the responsibility of the operator whomust be a suitably qualified and authorised person. Ensure that your fingers are behind the protective barrier whenusing the probe.4Subject to change without notice

4.1 Switch OnWhen the probe is switched on, the green LED will illuminate. The LED starts flashing when the battery voltage is toolow for normal operation and warns the user that it requireschanging. This procedure is described in Section 4.5.4.2 Zero AdjustmentThe output zero offset voltage of the probe may changedue to thermal shifts and other environmental conditions.To null the output voltage depress the Auto Zero button.Ensure that the probe is away from the current carryingconductor whilst the probe is being nulled.4.3 Current Measurement– Switch on the probe and check that the LED is lit.– Connect the output lead to an oscilloscope, multimeteror other measuring equipment.– Zero the probe using the Auto Zero button.– Clamp the jaws of the probe round the conductor ensuring a good contact between the closing faces of thejaws.– Observe and take measurements as required. Positiveoutput indicates that the current flow is in the directionshown by the arrow on the probe.4.4 Auto Power OFFIn order to save battery life, the probe will automaticallyswitch itself off after approximately 10 minutes. To disable the Auto power off function, Switch Off the probe andSwitch On whilst pressing the auto zero button. The redLED will illuminate and the probe will stay On until switchedoff again.4.5 Battery ReplacementWarningTo avoid personal injury, always ensure the probe is removedfrom any live electric circuit, and leads are disconnectedbefore removing the battery cover. Never operate the probewithout the battery cover fitted.The green or red LED will flash when the minimum operating voltage is approached. Use the following procedure.– Unclamp the probe from the conductor, turn it off usingthe On - Off switch and disconnect the output leads,from external equipment.12Subject to change without notice
