10.4 Logbookconguration

In“Logbookconguration,”theuserconguresinformationtobesavedtoalogbookorinitializes

the logbooks.

Logbooks are used to keep an electronic record of events such as error messages, calibrations,

andprogrammeddatachanges.Byreferringtothislog,userscan,forinstance,easilydetermine

maintenance or replacement schedules.

In“Logbookconguration,”theusercanselect“Off,”“1-1,”or“1-2”foreachitemofinterestto

be logged. This can be done for items displayed on the Settings logbook 1/3 to 3/3 screens.

Assigning 1-1 or 1-2 to each item allows information to be organized and logged in a logbook.

NOTE

Some events such as power-on are saved into the logbook “1-1”. This logbook may be full earlier.

It is recommended that important information be saved into the logbook “1-2”.

For“Eraselogbook”,aspeciedlogbook“1-1”or“1-2”canbeerasedindividually.

When the “Warn if logbook full” is set to “Yes”, a warning is given when the logbook come to near

full(maximum13pages).

NOTE

When the logbook gets full, the oldest information is erased automatically.
