WARNING section on page 1 Making Measurements with the AC Current Probe Model MNO5 Connect the black lead of the current probe to common and the red lead to the AC voltage range on your DMM or other voltage measuring instrument The 10A range has an output 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 For best accuracy avoid if possible the proximity of other conductors which may create noise Tips for Making Precise Measurements 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 measuremen
3. AC Current Probe Model MNO5 User Manual DESCRIPTION The MNO5 Cat 2129 19 is small compact AC current probe Designed to meet the most stringent dema nds in industry and electrical contracting they also meet the latest safety and performance standards The probe has two measurement ranges 10 and 100Arms which makes it a perfect tool for meas other urement with DMMs recorders The Model MNO5 is compatible with any voltmeter multimeter or current measurement instrument with an input impedance greater than 1MQ To achieve the stated accuracy use the probe with a voltmeter having an accuracy of 0 75 or better 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 ra
