1-9 Calendar Function
The values of the calendar built in a main unit of the MICREX-SX series SPF can be monitored and set from D300win. They can
also be monitored and set from an application program.
1-9-1 Calendar value range
The calendar can measure calendar values from 1970-01-01 00:00:00 through 2069-12-31 23:59:59.
Notes:
One second after 2069-12-31 23:59:59, the date and time will turn back to 1970-01-01 00:00:00.
1-9-2 Calendar accuracy
The accuracy of the calendar (clock) in a main unit is ±20 seconds per day (at an ambient temperature of 25°C, when active).
Notes:
The accuracy of the calendar varies depending on the environmental conditions such as an ambient temperature.
When a main unit is to be used in a system where a high calendar accuracy is required, measure the actual calendar accuracy
and determine the inspection (clock calibration) period.
