3. AC Current Probe Model MN103 User Manual DESCRIPTION The MN103 Catalog 1031 02 measures leakage current and low currents from 1 mA and measures current on 5A secondaries This current probe provides AC current measuring capabilities to instruments with mV inputs The Model MN103 offers a 5 ft lead with safety 4mm banana plug WARNING These safety warnings are provided to ensure the safety of personnel and proper operation of the instrument Read the instruction manual completely and follow all the safety information before attempting to use or service this instrument Use caution on any circuit Potentially 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 maximum voltage ratings given Safety is the responsibility of the operator ALWAYS connect the current probe to the display device before clamping the probe onto the sample being tested ALWAYS inspect the instrument probe probe cable and output terminals prior to use Replace any defective parts immediately NEVER use the current probe on electrical conductors rated above 250V Use extreme caution when clamping around bare conductors or bus bars INTERNATIONAL ELECTRICAL SYMBOLS E This symbol signifies that the current probe is protected by double or reinforced insulation Use only factory specified replacement parts when servicing the instrument A Thi

5. put signal of 1mV mA AC This means that for 10A AC in a conductor around which the probe is clamped 10V AC will come out of the probe leads to your DMM or instrument The 100A range has an output signal of 1mV A AC This means that for 100A AC in a conductor around which the probe is clamped 100mV AC will come out of the probe leads to your DMM or instrument Select the range on your DMM or instrument which corresponds best to the measured current If the current magnitude is unknown start with the highest range first and work down until the appropriate range and resolution is reached Clamp the probe around the conductor Take the reading on the meter and multiply it by the output signal used to obtain the measured current e g If the meter reads 100 5mV range 1mV mA then current equals 100 5mA AC Unclamp the probe from the conductor before disconnecting it from your DMM or instrument e For best accuracy avoid if possible the proximity of other conductors which may create noise Tips for Making Precise Measurements e When using a current probe with a meter it is important to select the range that provides the best resolution Failure to do this may result in measurement errors e Make sure that probe jaw mating surfaces are free of dust and contamination Contaminants cause air gaps between the jaws increasing the phase shift between primary and secondary It is very critical for power measurement MAINTENANCE Warning e For
