Measuring principle and accuracy
Measuring principle
Voltage is measured directly at the load and current is
measured by a precision shunt.
Measuring rate
approx. 1 second
Sampling rate
approx. 2000 Hz
Open-circuit
recognition
If I < 0,002 Ampere current and power values are set to zero.
It P < 0,2 Watt power values and current are set to zero.
In this case the power factor is set to 1,00.
The type of resistance is set to ohm-resistance.
EEPROM-Memory
All readings are saved even after unplugging
Measuring error
± 0,3 % ± 3 digit from reading at power factor > 0,3
