AC Current ProbeModel MN02User ManualDESCRIPTIONThe Model MN02 (Cat. #2129.20) is a small, compact AC current probe and is designedto meet the most stringent demands in industry and electrical contracting. This instrumentmeets the latest safety and performance standards. The probe has a measurement rangeup to 100 Arms which makes it a perfect tool for measurement with DMMs and recorders.The Model MN02 is compatible with any AC ammeter, multimeter, or other currentmeasurement instrument with an input impedance lower than 10 Ω. To achieve the statedaccuracy, use the probe with an ammeter with an accuracy of 0.75 % or better.WARNINGThese safety warnings are provided to ensure the safety of personnel and proper operation of theinstrument.• Read the instruction manual completely and follow all the safety information before attempting to useor service this instrument.• Use caution on any circuit: high voltages and currents may be present and may pose a shock hazard.• Read the Safety Specifications section prior to using the current probe. Never exceed the maximumvoltage ratings given.• Safety is the responsibility of the operator.• ALWAYS connect the current probe to the display device before clamping the probe onto the samplebeing tested.• ALWAYS inspect the instrument, probe, probe cable, and output terminals prior to use. Replace anydefective parts immediately.• NEVER use the current probe on electrical conductors rated above 600 V in overvoltage category III(CAT III). Use extreme caution when clamping around bare conductors or bus bars.INTERNATIONAL ELECTRICAL SYMBOLSThis symbol signifies that the current probe is protected by double or reinforced insu-lation. Use only factory-specified replacement parts when servicing the instrument.This symbol signifies CAUTION! and requests that the user refer to the usermanual before using the instrument.This symbol signifies that this is a type A current sensor and that application nearand removal from HAZARDOUS LIVE conductors is permitted.This symbol signifies a voltage limiting circuit.DEFINITION OF MEASUREMENT CATEGORIES (CAT)CAT IV: For measurements performed at the primary electrical supply (< 1000 V), such asprimary overcurrent protection devices, ripple control units, or meters.CAT III: For measurements performed in the building installation at the distribution level,such as hardwired equipment in fixed installation or circuit breakers.CAT II: For measurements performed on circuits directly connected to the electricaldistribution system, such as measurements on household appliances or portable tools.
