Time Date and time
The date and time are displayed separately. When moving to the right within the
list structure, the date is displayed after the time. When moving to the left, only the
time is displayed.
After pressing the key combination
ENTER
for entry (set clock), the date and time
are displayed together (initially without seconds). The input mark (cursor) is l o-
cated on the right-hand display position, then after pressing
®
again, the com-
plete value is moved to the left so that the seconds can also be changed.
The time is updated in synchronism with the operating cycle
OCyc (see below) or
after key operation.
MdTim Daylight saving
"0" = Automatic changeover between summer and winter time OFF.
"1" = Automatic changeover between summer and winter time:
Summer time begins on the last Sunday in March at 2:00 hrs. and ends on
the last Sunday in October at 2:00 hrs.
"2" = Switchover at set times
The start and finish of daylight saving is set under the addresse s 1:4A0 and
1:4A8. The times must be set each year.
MCyc Measurement cycle time
Measurements (e.g. pressure, temperature), computed values (e.g. K -value, con-
version factor) and counter readings are updated on this cycle.
To ensure all functions,
MCyc must only be set to integer factors of 60 seconds,
e.g. 5, 10, 15, 20, 30 or 60 seconds. In addition MCyc must be an integer factor of
OCyc (see below). Entries of values not satisfying these conditions are, where
possible, corrected automatically. If the EK220 does not find any suitable value
during the correction attempt, it rejects the entry with error message "6". (

2.3.2 )
In applications subject to official calibration EN 12405 MCyc must be less than or
equal to 30 seconds.
The standard setting is 30 seconds.
With settings less than 30 seconds the battery service life is reduced. (
