Seca 780 - Recalibration; Technical data

From the quartz's 4.19MHz a time base is derived which controls all timed processes in the scale.
These are, for instance, various timeouts and the on-time.
After expiry of the on-time, the supply voltage for the bandpass filter, for voltage measurement and
for the EEPROM is switched off. All ports are setto zero-signal level and the quartz is stopped.
Recalibration
In order to compensate for linear measuring errors of the scale, which can, for instance, occur as a
result of the different forces of gravity at different geographical points, the module has a recalibration
function. Recalibration is performed via the SeSAM bus by means of a display module.
