Photometer 7500 BT
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 Bluetooth
• Log.txt - the data log file stored in a
comma separated value (csv) format
Operating software or calibration library can
be updated by dragging a new version to the
instrument - contact [email protected]
for new software if this option is required. Any
updates to operating software will be notified
via the www.palintest.com\know portal.
Downloading the result log is carried out by dragging
the LOG.txt to the local desktop and opening the file
with any program that can open CSV format files.
For more information regarding extracting and
opening result logs using the Hard Disk mode
visit www.palintest.com/know.
COM Port
The instrument behaves as if connected to the PC
serial port via RS232 when connected in COM Port
mode, allowing remote control from an external
software system and data upload. This allows
backwards compatibility with software written for
earlier models of Palintest instruments. In this mode,
the PC requires installation of a USB virtual COM
Port driver, available from www.palintest.com/know,
and the availability of software operating as a
virtual com port.
A large number of third-party software systems
are available to provide data upload and remote
control of testing using the COM port mode.
Please contact your local Palintest representative
for more details.
