Applications
The power multimeter is extremely rugged and reliable with a
housing made of impact resistant ABS. With a resolution of
60,000 digits and more than 35 different measuring functions, it’s
been developed for professional use.
Features
Power and Energy Measurement
The METRAHIT ENERGY is a compact power meter for direct and
alternating current in single-phase systems. The electrical circuit
can be connected either directly, or via a current transformer. If a
current transformer is connected to the multimeter (mA/A input),
all current and power displays are represented with the correct
value based upon the selected transformation ratio.
Universal power measurement includes the following measuring
functions: active, reactive and apparent power, power factor and
energy.
Beyond this, the mean power value can be generated over a
specified time period (e.g. 15 min.), and the corresponding maxi-
mum value can be recorded along with time of occurrence. Suit-
able AC current transformers with current output are listed on
page 10.
Using shunt resistor SR9800 in combination with current clamp
sensor CP1800 allows for the power and energy measurement of
DC applications with high currents as well, such as for measure-
ments at photovoltaic systems.
Systematic Voltage Quality Analysis
The METRAHIT ENERGY is equipped with a function for acquiring
and recording power disturbances which is unique amongst the
handheld multimeters. It allows for simultaneous, continuous
recording of voltage characteristics and event-triggered recording
of the following disturbances:
Under and overvoltage with start time, duration and extreme value
Under and overvoltage of the half-period RMS value (dips and
swells) with start time, as well as min. and max. values
Momentarily exceeded values with a duration of greater than
1 ms (peak) with time of occurrence and maximum value
Steep transients with a rise time of 0.5 to 5 ms within a range
of 200 to 1000 V including time of occurrence, relative voltage
value and the previous 1 ms instantaneous value
Harmonic Analysis
In the
and current measurement (A) switch positions, har-
monic analysis is performed approximately once per second
using 32 sampling values per mains period (adjustable to 16.7,
50, 60 or 400 Hz).
FFT (fast Fourier transformation) makes oscillations up to the 15
th
harmonic available to this end. These are used to calculate the
RMS values of the fundamental harmonic (HD 1) and the individ-
ual higher harmonics (HD 2 ... 15), as well as total harmonic dis-
tortion (THD). RMS values and harmonic components are dis-
played in each case (RMS values relative to the RMS value of the
fundamental harmonic). Harmonic analysis is also available for
current clamp measurement.
