Leakage Current Clamp Meter

AC Leakage Current Clamp With High Current Measurement Up To 1000A


Identifying deterioration of installation and other causes of "nuisance tripping" in live circuits is not always a straightforward matter. Problem of access and isolation may make the inspection costly. Then, lets look at CEM Leakage Clamp Meter designed to take the stress out of inspecting live installations.

Now, thanks to unique AC Leakage Clamp Meters developed by CEM, we can make not only a precise measurement of the earth leakage current in a circuit, but also an instant assessment of the cause of that leakage without shutting down the installation.

At the first glance, the CEM Leakage Clamp meters appear to be conventional clamp ammeters. However, the special construction of the clamp shielding, allows us to measure tiny out- of-balance currents between any conductors enclosed within the transformer jaws. 


  • Accurate AC digital clamp meter for leakage current measurement
  • 100uA high resolution on 200mA range
  • Shield transformer jaws to minimizes the effect of external stray magnetic field
  • Large jaw with 68 mm diameter
  • Five Ranges (200mA, 2A, 20A, 200A, 1000A) for all application.
  • A filter circuit is designed to eliminate the effect of high frequency noise and harmonics by setting the frequency selector switch at the 50/60 Hz position for AC current measurement
  • Large 3 - 1/2 digits backlit LCD
  • Fast bargraph display (20 times/sec.) for transient observation
  • Continuity Test
  • Max/Min record function
  • Peak Value Measurement
  • 600V overload protection for DC/ACV, ohm range measurement
  • Easy single rotary switch for any function selection
  • Data Hold Function
