System Lock
To prevent unauthorised or inadvertent changes
to the System settings or log deletion a four digit
code can be used to lock several options.
The default code is set to 6812. To change the
System Lock code follow the on-screen prompts
to choose a memorable four digit number.
When the System Lock is applied, the items accessible
within the System Mode are limited until the unlock code
is entered. Access is limited to viewing the result log,
adjusting the backlight, contrast and Bluetooth settings.
User Defined Tests
In addition to the many available calibrations/
methods, the Photometer 7500 Bluetooth provides
additional capability for up to 30 User Defined
Tests. A User Defined Test is built using a table of
calibration data consisting of up to 10 data pairs
of absorbance and concentration.
Download or request a copy of Usertestbuilder.exe
(suitable for Windows operating systems) from
our websites to define the details and calibration
data as shown below:
Connect the Photometer 7500 Bluetooth to the
PC using the USB cable provided, ensuring the
instrument is set to Hard Drive mode.
Once data is complete press “Download this test”
to transfer the method details and calibration.
The Photometer 7500 Bluetooth will respond
with Test Data Accepted.
Alternatively save the test data as a *.txt file and
drag and drop onto the Photometer 7500 Bluetooth.
User Defined Tests are stored in Phot Numbers 900 - 929
to avoid confusion with standard Palintest calibrations.
Press OK once the test has been uploaded
to view the test in the User Defined Test list.
A number of options are available within
the Edit User Defined Test menu:
BACK

EDIT

DELETE
remove the test from the instrument
