• Power measurement (W, VAr, VA, PF): active, reactive and apparent power with extreme values, power factor
• Mains quality analysis: recording of over and under voltage, dips, swells, voltage peaks and transients in 0, 50 and 60 Hz systems
• Harmonic analysis: RMS values and distortion components up to the 15th harmonic at 16.7, 50, 60 and 400 Hz
• Measurement data memory for up to 300,000 measured values

The new, professional METRAHIT ENERGY multimeter is exceeding all previous performance limits. Thanks to simultaneous TRMS current and voltage measurement (AC, AC+DC and DC) with a resolution of 60,000 digits, all-important power quantities can be precisely acquired.

Special measuring functions

• Current measurement with current clamp transformers and sensors, transformation ratio is taken into account at the display
• Measurement data memory for up to 300,000 measured values
• The instrument is fully remote controllable without activating the rotary switch or changing current sockets

Automatic / Manual Measuring Range Selection

Measured quantities are selected by means of a rotary switch and a function key. The measuring range is automatically matched to the measured values. The measuring range can also be selected and locked manually with a key.

Peak Value Monitoring for Automatic and Manual Measuring Range Selection

The peak value is measured in addition to RMS measurement in the V / A DC, AC and AC+D functions, as well as for power measurement. If the peak value exceeds the valid range of the corresponding measuring path, the instrument is switched up one range, even if the displayed RMS measured value has not yet reached the threshold value. If the momentary measuring range is manually locked, (–)OL appears to indicate the peak value. This assures that measurement only takes place in the permissible range for these functions (e.g. during measurement of a signal with a high crest factor or measurement of the DC component of high AC+DC voltages).

Measurement with Current Transformer Clamps and Sensors

Current transformer clamps and sensors are used for current measurements without interrupting the circuit under test, and for high amperages (> 16 A). All E series multimeters offer convenient measurement with current clamps. The measured current value is automatically calculated for the user with the help of the adjustable clamp factor.
