[01-04-04]
You can use this function to set the actual date and time.
The analyzer has a system clock which is not protected against power failure (not a real-time
clock). The clock is set at 01-01-00 00:00 when the analyzer is started.
This function allows you to exactly set the date and time. This is particularly important when you
need to assign a specific point in time to faults stored in the logbook. This can be helpful when
troubleshooting.
After selection of this function an editing field appears in which you can enter day, month and
year as "New date". Hours (24-hour system) and minutes are entered as "New time".
The set data are imported when you press the third soft key ("Set Clock"). The data then appear
as an active display at the bottom of the screen.
Note
Date and time must be reset in case of a power failure.
