Avatars
In the User Mode (see Section 6.7), an avatar can be assigned to each new user. This helps
to clearly identify the logged-in user. It will be shown in the upper right hand corner of the
start screen. If an avatar has not been selected, the instrument will use the default avatar. In
the
“Open Mode,” an avatar can only be changed through the user account. In the user
mode, all logged-in users and the administrators are able to change their own avatar. To
select an avatar, press the
icon in the start screen (
Please note: User mode has to be
activated
) followed by
“Select avatar.” A dynamic list with the stored avatars will open. By
selecting one of the entries, it will be set as the avatar. To add an avatar, press the
icon
and select an image file from a connected USB storage medium. You can delete the list entry
by pressing and holding down the list entry for several seconds and then confirming with the
icon.
Please note: MACHEREY-NAGEL recommends the use of images with a resolution of 180 x
180 pixels.

printer settings, please also see Section 6.1.6. For the continuous printing of measurement

automatically after measurements are made, provided that
“Print automatically” has been
activated in the settings menu for the printer.

Scanner
Connect the scanner to one of the instrument’s USB-A interfaces. An acoustic signal will
confirm that the scanner has been connected. (

.
After
connecting the scanner, it can be used anywhere the keypad appears. A string of up to 20
characters can be entered. The scanner can be used to add sample information conveniently
following the measurement. To do this, after the measurement process, press the icon with
the desired sample information and then, in the list that opens, press the
icon to
activate the keypad. The barcode can now be scanned and confirmed by pressing Enter. The
scanned sample information is stored together with the measurement result. The barcode
scanner can be used in any case a keyboard or numeric field is opened.
