CAPACITIVE TOUCH SELF CALIBRATION PROCESS
In a reported fixed 64s interval the average, minimum and maximum value of the capacitive touch sensor is calculated.
If the conditions are stable (without interruptions) then the average value of the capacitive touch sensor is used as a reference
value.
If the new reference value deviates sufficiently from the permanently stored value, it is permanently saved.
Permanently stored value is used when the power is turned on.
ENERGY COUNTERS
There are two sets of energy registers – four non-resettable registers which can be assigned for active energy (MID approved),
reactive energy (national approval) or apparent energy (no approval).
The meter with MID approval should have at least one register with active energy measurement.
There are additional 16 energy registers which can be parameterised by the user regarding type of energy, active quadrants,
direction of counting and tariff and they can also be resetted using MODBUS command or cap touch.
On the LCD up to two energy counters are displayed.
There is the lock sign for the fixed legally relevant non-resettable counters, the counter designation, the sign of currently
active register, an additional code and the unit.
For the code the user can choose between the OBIS code or letter description code (the latter is the default). The 9-digit
numerical number shows the value of the energy. The decimal dot is fixed and resolution is fixed to 100 Wh. The screen is
displayed for the pre-set cyclic period.
PLEASE NOTE
In compliance with the MID directive, where the final test is done before selling the products, it may happen that the MID
energy meters show a low energy consumption even if they are new.
This can only happen to relatively small percentage of meters for each production lot and the highest value should be
around 6 kWh for the Active Imported Energy
