Daylight saving time (DST) can be enabled as one of two formats:
- Fixed date option: If you choose a fixed date option, you set the format according to a fixed date for the DST switch: in the format of month/ day/ hour/ minute/ adjust time (in minutes).
- Non-Fixed date option: If you choose the non-fixed option, DST will be implemented by which day of which week, with the format as month/ which day/ which week/ hour/ minute/ adjust time (in minutes).
Setting the DST will cause the meter to automatically switch to and from daylight saving time. When the clock starts to run on daylight saving time, the meter will automatically adjust its clock to a time period in advance, while the clock is running to the end of daylight saving the meter will adjust its clock back to a previous time period.
Make sure to click "Update Device" after making any changes in order to save the settings. If no errors are found then the TOU energy accumulation will begin.
For convenience, you can also save and load these settings on to other AcuRev meters.
