BENNING CM 12
Application:
For all sophisticated measuring tasks in industry and trade. Monitor, store and share the measured values for further evaluation within your organization via the free "BENNING MM-CM Link" app.
Features:
- precise due to TRUE RMS measuring method (AC, AC+DC)
- measurement of inrush currents (motors etc.)
- recording of load profiles on single-phase and three-phase loads in AC/DC mains
- simultaneous detection of current (A) and voltage (V) for effective power (W) and power factor measurements
- continuity test (30 Ω - 100 Ω), diode test (0.8 V) and bipolar phase sequence test
- low-pass filter (HFR) for measurements at pulsed motor drives
- harmonic measurement (THD) for evaluation of the mains quality
- optional: AC current measurement up to 3,000 A by means of flexible AC current transformer BENNING CFlex 1 (044068)
- data logger function “LOG” (10,000 measured values, sampling arte: 1 s to 10 min.)
- memory function “MEM” (1,000 measured values, automatic storage of stable measured values and manual storage with a simple keystroke)
- Bluetooth® Low Energy 4.0 interface
- IOS and Android app for data link to smartphone/tablet
- AUTO SENSE function for automatic selection of measuring ranges and functions
- integrated Volt sensor for non-contact cable break detection (red LED)
- easy selection of menu functions via cursor key
- memory of measured value (HOLD), peak value (PEAK) and maximum/minimum/average values (MAX/MIN/AVG)
- measuring category CAT IV 600 V, CAT III 1000 V
- incl. carrying case, batteries and measuring leads

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.
