BENNING CM 9-1 and CM 9-2

TRUE RMS Leakage Current Clamp Meter with a resolution of 1 μA in the 6 mA measuring range

BENNING CM 9-1 and CM 9-2

Error-related leakage currents are caused by weak insulation or insulation damages. The BENNING CM 9-1/ CM 9-2 allows quick and precise localization of all error types. By means of preventive measurements, possible damages due to uncontrolled leakage currents can be avoided in advance.

Common features:

  • measurement of leakage currents and differential currents in electrical systems (VDE 0100/0105), devices (VDE 0701-0702) and machines (EN 60204-1/ VDE 0113-1)
  • DIN EN 61557-13 defines requirements for “current clamps for measuring leakage currents in electrical installations”, e. g. protection against external magnetic fields: class 2, magnetic field ≤ 30 A/m; frequency range: min. 40 Hz to 3rd harmonic of the mains frequency (150 Hz), recommended use: railway (as of 15 Hz), industry (up to 1 kHz)
  • DIN EN 61557-16 (requirements for appliance testers) defines filters with fg = 1 kHz for measuring protective conductor currents IPE in electrical and medical electrical devices
  • precise due to TRUE RMS measuring method
  • reliable and easy detection of insulation faults (e.g. defective cables, loose terminals, contamination, moisture)
  • measurement without switch-off during normal operation of the system/ device
  • ideal for preventive maintenance and fault localization (protection against damages and personal injury, blackouts etc.)
  • precise and reproducible measuring results up to 60 A

BENNING CM 9-1 with multimeter functions:

  • universally applicable for current measurements (60 A), voltage measurements (600 V), resistance measurements (600 kΩ) and continuity tests
  • Low-pass filter (40 Hz - 70 Hz) for rejection of high frequency interference signals
  • memory of measured value (HOLD) and peak value storage
  • incl. carrying case, measuring leads and batteries

BENNING CM 9-2 with Bluetooth® function and App:

  • Bluetooth® Low Energy 4.0 interface
  • IOS and Android app for viewing, storing and sharing measured values via smartphone/tablet
  • Low-pass filter (50 Hz - 60 Hz) for rejection of high frequency interference signals
  • memory of measured value (HOLD) and maximum/minimum value (MAX/MIN)
  • incl. carrying case and batteries

Industrial environments requires TRUE RMS measuring instruments!

Non-linear loads arising e.g. from motor drives with adjustable speed, frequency converters or mains supply units for office equipment and LED lamps generate a reactive power in the mains. As a result, multimeters and current clamps working with the so-called averaging measuring method ("RMS") will display the measured values with reduced accuracy.

In many cases and particularly in industrial environments, it is therefore absolutely necessary to use state-of-the-art "TRUE RMS" measuring instruments. The "TRUE RMS" measuring method indicates the actual effective value of an alternating current correctly – irrespective of whether the signal waveform of the current is sinusoidal or distorted.
