Measuring accuracy (500kHz version)
Measuring accuracy of cos
ϕϕϕϕϕ
Accuracies based on 1. sinusoidal voltage and current 4. definition of power range as the product of
2. ambient temperature 23 °C current and voltage range, 0 ≤ IλI ≤ 1
3. warm up time 1h ( λ=Power factor=P/S)
5. calibration interval 12 month
Other values All other values are derived from the values for current, voltage and active power. Accuracies for the derived values depends on
the functional relation (e.g. S = I * U, ∆S/S = ∆I/I + ∆U/U)
Internal time base ±25ppm at 23°C
Frequency measuring 0.05Hz...500kHz ±0.01% of measuring value, measuring channel selectable.
Display of measured and computed values

With standard abbreviation of measured magnitudes, numeral values 6 digits (0...999999), with sign, decimal point and unit
(e.g. I
trms 0.73851mA), 1 to 8 values can be displayed simultaneously, selectable via default or user defined menus
Voltage/current trms value, peak values (min, max, pp), rectified value (rect), mean value (dc), trms value of ac component (ac),
form factor, crest factor
Power Active power (P), reactive power (Q), apparent power (S), phase angle ( ϕ), power factor (λ)
Impedance Amount (Z), real- und imaginary part of resistor in serial equivalent circuit
Integrated values depending on The integration can be controlled manually, automatically using start and stop times, via external trigger or remote
the measuring time controlled via computer interface
Energy, Charge active energy (Ep), reactive energy (Eq), apparent energy (Es), charge (q)
Date and time, measuring time current date (day, month, year) with time (hour, minutes, seconds), accu buffered real time clock, start time for measurement,
running measuring time, on-time, each with days, hours, minutes, seconds
Adjustable parameters Scaling factors for external shunt, current and voltage transducer
Synchronisation Synchronisation is made on the periodicity of the measured signal. Periodicity can be determined by the signals u(t), i(t), p(t),
u²(t), i²(t), each of them can be adapted with selectable filters. By this stable displays also with pulse width modulated signals
(e.g. frequency inverter) and amplitude modulated signals (e.g. electronic ballast). Synchronization also by „Line“ and „External“
