AC Current ProbeModels MN210 and MN211User ManualDESCRIPTIONThe MN210/MN211 (Catalog #2115.72 and #2115.73) are the latest in compact AC Current probes.Designed to meet the most stringent demands in industry and electrical contracting, they also meet thelatest safety and performance standards. The probes have a measurement range up to 240 Arms whichmakes them perfect tools for measurement with DMMs, recorders, power and harmonic meters. TheModels MN210/MN211 are compatible with any AC ammeter, multimeter, or other current measurementinstrument with an input impedance lower than 1. To achieve the stated accuracy, use theMN210/MN211 with an ammeter having 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 attemptingto use or service this instrument.• Use caution on any circuit: Potentially high voltages and currents may be present and may posea shock hazard.• Read the Safety Specifications section prior to using the current probe. Never exceed themaximum voltage ratings given.• Safety is the responsibility of the operator.• ALWAYS connect the current probe to the display device before clamping the probe onto thesample being tested.• ALWAYS inspect the instrument, probe, probe cable, and output terminals prior to use. Replaceany defective parts immediately.• NEVER use the current probe on electrical conductors rated above 600V in overvoltagecategory 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 insulation. Useonly factory specified replacement parts when servicing the instrument.This symbol signifies CAUTION! and requests that the user refer to the user manual beforeusing the instrument.This is a type A current sensor. This symbol signifies that application around and removal fromHAZARDOUS LIVE conductors is permitted.DEFINITION OF MEASUREMENT CATEGORIESCat. II: For measurements performed on circuits directly connected to the electrical distribution system.Examples are measurements on household appliances or portable tools.Cat. III: For measurements performed in the building installation at the distribution level such as onhardwired equipment in fixed installation and circuit breakers.Cat. IV: For measurements performed at the primary electrical supply (<1000V) such as on primaryovercurrent protection devices, ripple control units, or meters.RECEIVING YOUR SHIPMENTUpon receiving your shipment, make sure that the contents are consistent with the packing list. Notifyyour distributor of any missing items. If the equipment appears to be damaged, file a claim immediatelywith the carrier and notify your distributor at once, giving a detailed description of any damage. |
