Sample ID
The Photometer 7500 offers the option to create
up to 24 unique alphanumeric Sample IDs. Sample
IDs are added to the result data automatically but
deleting IDs does not affect the result log.
To create a new Sample ID, select Sample ID
and use the up/down keys to select a blank field.
Select New and press OK.
Alphanumeric characters are entered/edited using
the 0-9 keys or the up/down keys. Press and hold
the 1 key to toggle between upper and lower
case characters.
After entering a character, the cursor automatically
moves to the next position if no key is pressed.
Alternatively press the right key.
Up to 10 characters can be added for Sample IDs,
including spaces.
To edit characters use the left/right keys to select
the desired character. Press and hold the left key
to delete the character or change the character
using the entry mode.
When the Sample ID is correct press the OK key to
create the ID and return to the Sample ID list. The
Photometer 7500
new Sample ID will be displayed in the Sample list.
Choose the Sample ID to be used by scrolling through
the list and pressing the OK key on the desired choice.
The instrument will return to the System menu.
To modify or delete an existing Sample ID, highlight
the ID and select Edit. Choose either Edit to modify
the existing entry or Delete to remove it from the list.
USB Interface
The waterproof USB interface provides both
communication between the Photometer 7500
and a PC and an alternative mains power
source via the adaptor.
When connected the USB icon will appear, replacing
the battery icon in the Info Panel, as power will
be preferentially drawn from the external source.
The USB data interface has a choice of two
operating modes - Hard Drive and COM Port. The
current status of the USB connection is shown on
the Info panel when the USB lead is connected.
Toggle between COM Port and Hard Disk mode in the
System -> USB menu by selecting the desired option.
The USB connection supports software update and
data download through a simple 'drag and drop'
approach when operated in Hard Disk mode.
Hard Drive
The instrument appears as a removable hard drive
when connected to a PC in Hard Disk mode. Upon
connection the remote drive will have the
following files included:
• 7500_***.afx.*** where * represent
version numbers of software - this is
the operating software for the Photometer
7500
• Log.txt - the data log file stored in a
comma separated value (csv) format
