Convert from CE
counts to pulses.
The number of

mand interval.
Expected number of
cycles per second
of mains. 0 disables
the software RTC

Center temperature
of the crystal.
CE’s w0sum units per pulse,
rounded up to next largest CE
count so Wh accumulation and
display is always rounded down.
Count of minutes.
(60/interval)*interval = 60.
