3.15 Measurement Calibration
Once the 78M6612 energy measurement device has been installed in a measurement system, it is
typically calibrated. A complete calibration includes the following:
?
?
Calibration of the metrology section, i.e. calibration for tolerances of the current sensors, voltage
dividers and signal conditioning components as well as of the internal reference voltage (VREF).
Establishment of the reference temperature ( Section 3.3 ) for temperature measurement and
temperature compensation ( Section 3.4 ).
The metrology section can be calibrated using the gain and phase adjustment factors accessible to the
CE. The gain adjustment is used to compensate for tolerances of components used for signal
conditioning, especially the resistive components. Phase adjustment is provided to compensate for
phase shifts introduced by certain types of current sensors or by the effects of reactive power supplies.
Due to the flexibility of the MPU firmware, any calibration method, such as calibration based on energy, or
current and voltage can be implemented. It is also possible to implement segment-wise calibration
(depending on current range).
