Hotkey Entry Mode
This option provides single button access to the
ten most frequently used tests by assigning each
to a unique position on the numerical keypad.
To assign a test to a specific Hotkey (0-9), firstly
ensure that ‘Hotkey Mode’ is enabled. This is
shown by the
indicator on the Info Panel.
Select the Hotkey Test List from the Mode menu.
The ten available positions are listed along with
assigned or empty slots.
Select the Hotkey to assign (0-9) and use the
up/down arrows to highlight the required
parameter/method from the Choose a Test list.
Press OK and the test will be assigned to the
defined number.
Units
The Photometer 7500 Bluetooth offers the choice
of result expressed in mg/l, ppm, mmol/l, µmol,
g/l and µg/l.
Changing the result units will not affect the result log.
Dilution Factor
When samples are above the test range, indicated
by >> on the result screen, a dilution procedure can
be used. Setting Dilution Factor to On will prompt
the Photometer 7500 Bluetooth to automatically
request the dilution factor when carrying out a test.
Change the dilution factor by using the up/down
arrows or manually type the dilution factor. The
instrument will automatically correct the result
for the dilution and display the corrected result
(which will also be stored in the result log).
The maximum dilution factor permitted is 99.
If the calculated result exceeds the available number
of permitted characters >> will be displayed
NOTE:
do not use sample dilution when
measuring pH or alkalinity.
