DMM v/s Clamp Meters

• By Fluke India

• Myth
• A clamp meter is a DMM with a set of inductive
  jaws replacing the test leads
• Reality
• A DMM is a voltage measuring tool with some
  current abilities
• A clamp meter is a current-measuring tool with
  some voltage abilities

• Differences
• DMM- Allows you to do electronic work because of
  its high resolution, it measures in milli units
• Clamp Meters- Electrical work is its forte, it
  measures to the nearest tenth of a unit, rather
  than in the milli-units you find in a DMM.

Situations Where Both Instruments are Required

• Measure an analog conveyor speed signal and the
  respective motor current simultaneously, so you
  can calibrate the system for the required process
  flow
• Monitor solenoid output while monitoring input
  from the PLC, so you can test the solenoid
• Simultaneously measure electronic voltages and
  electrical currents at a motor drive, to
  troubleshoot line speed fluctuations
• Monitor feeder voltage and current
  simultaneously, to troubleshoot nuisance trips.

Different Instruments for Different Jobs

• Basic DMM - Only for basic voltage measurements
• High End DMM - For job that require power quality
  work
• Basic Clamp Meter - To ensure all three phases on
  your feeders are pulling the same current
• Advanced Clamp Meter(with logging capabilities) -
  For resolving intermittent breaker trips
