This meter is a handheld and battery operated professional automotive multimeter designed to provide troubleshooting solutions to the most difficult problems encountered with today’s sophisticated electrical / electronic systems like the Integrated Starter Generator system or the Integrated Starter Alternator system of the modern electric vehicles (EV or HEV or FCV, etc.)
   * EV = Electric Vehicle, HEV = Hybrid Electric Vehicle, FCV = Fuel Cell Vehicle

For troubleshooting the electric or hybrid electric vehicles, current measurement (especially without interrupting the supply from the battery or other current carrying conductors) is more important and effective than voltage measurement from a technical, economical and process point of view.

The more important or essential checking points in electric or hybrid electric vehicles than those of the conventional vehicles are as follows: 

  • Battery leakage current (normally around 15mA), when all systems are      turned off, which is used as a quality indicator in an Electrical Check Out      System for production line quality assurance testing or as a fault identifier      for the diagnostic units in large service centers. 
  • Current drain of the ECU controlling the ISG (or ISA) system, which is as      low as 10mA when ignition is turned off, should be measured without      disconnecting the battery cable to prevent the ECU from losing the stored      data. 
  • Starting currents (or Cranking currents to the starter motor) or Alternator      currents up to 400 to 800A rms (or 1,250 to 1,350A peak) in the ISG      system. 
  • A lot of specially designed current sensors or transducers in the ISG      system should be checked if they are working properly.

    For these current measurements, we need a precision clamp-on low dc/ac current probe with 1mA resolution (or better) and a reading accuracy of 1% as well as a high dc/ac current probe with full-scale ranges of 400A (100mA resolution) and 1500A (1A resolution).The specially designed high and low current probes equipped with this meter as standard accessories allow fast and precise current measurements without interrupt the circuit problems.
