My photometer will not switch on
The Info Panel provides an ongoing indication of
power available from the battery supply. When the
voltage available falls below 3.0V the Photometer
7500 will not switch on as the available power will
not be sufficient to provide effective photometric
testing.
Use the USB cable to provide an alternative
power supply. If the photometer still fails to
switch on, contact your local Palintest partner
for service support.
My USB power supply is not working
Ensure your PC is not operating in power save
mode or the mains supply is not isolated.
Replace the cable with an alternative to ensure
the cable is not faulty.
USB Connection Issues
I cannot download my data
Check the USB mode is set to Hard Disk, not COM
port mode. In Hard Disk mode the data can be
'dragged and dropped' as with a conventional
memory stick and is available in CSV format.
Opening CSV data files can be accomplished by a
number of text editing or spreadsheet programs.
Where do I find the COM port drivers?
The latest drivers are available at
www.palintest.com
COM port drivers are provided for Windows
operating systems (Windows Vista, XP and 7).
Care and Maintenance
The Photometer 7500 contains no user-serviceable
parts internally. User maintenance is only
recommended for cleaning of the optical
chamber, changing batteries and validating
performance using the Check Standard Mode.
Cleaning the Optical Chamber
The optical chamber has been designed to
support removal and cleaning with a lint-free
cloth as required by removal of the access cover.
Photometer 7500
Do not use any of the following agents
when cleaning this optical chamber:
• Abrasive cloths
• Corrosive chemicals
• Any organic solvents
Do not overtighten the screws on re-assembly
to avoid damaging the access cover.
Replacing the Batteries
Remove the four retaining screws from the
battery cover and gently prise the cover free.
Replace all batteries at the same time.
Ensure on replacing the battery cover that
the gasket is correctly located to prevent any
water ingress. Tighten the screws carefully
but do not overtighten.
