The header of the report can be customized to the
style of the company. To change the header you
should place a picture called diffheader.jpg in the
DIFFiner folder. The header will now change into
the picture called diffheader.jpg. The folder
DIFFiner can normally been found in C:\Program
Files\Observator\DIFFiner or on the SD-card. It is
recommended to keep the same resolution as the
default header (800 x 120) to avoid lay-out
changes.
7.5 SD-card messages
The error SD failure can occur if the SD-card is removed
while the storage menu is opened (
which is strongly
discouraged!
). The DIFF will return to the main menu. If the
message occurs when the SD card is still present it may be
possible that the SD card is not inserted correctly. Please re-
insert the SD-card.
If the SD-card is removed during the writing of data an error
“SD failure
300” will occur. The number at the right will
count down. It is possible to reinsert the SD-card while the
counter is still active. The data will still be saved. Not
reinserting the SD-card will result in data loss.
If the DIFF contains corrupt data (caused by removing the
SD-card) it will show the warning “corrupt data”. The warning
disappears when you turn the selection button.
The rooms that are not corrupt can still be measured.
Put the SD-card back in the computer to restore the file
system. The SD-card will now automatically be restored
when DIFFiner starts.
