On models that display values down to two digits past the decimal
point, data is written into memory when the ones digit changes or
one hour after the previous writing.
On models that display values down to one digit past the decimal
point, data is written into memory when the tens digit changes or
one hour after the previous writing.
Integrated values that have not been written to memory are dis-
carded when the power is turned OFF.
