The test selection menu
appears when first starting
up Lumiso.
From most other screens,
pressing “back” once or
twice, will take you back to
the test selection menu.
Select a test, using the up and
down keys until the desired
test is highlighted.
These tube icons
will usually appear.
These indicate that the left
key is for “blanking” and
the right key is for “reading”
Please Note: The read icon
only appears after the blanking stage
has been completed. Lumiso will require
blanking to be repeated after 50
minutes or if it registers a significant
change in environmental temperature.

Blanking enables the instrument to set the correct zero value.
This ensures the final result will be accurate, even when testing
water that is cloudy or coloured.

12 Information Messages
Lumiso will display these messages as M numbers, if it
detects unexpected readings when making its optical
measurements
A common cause that can trigger any of these messages to be
displayed is contamination of the optical windows or stained
glassware. See sections Keeping the Optics Clean and How to
Get Accurate Results. If messages continue to be displayed,
please contact your local Palintest branch or distributor.
Message
Number Likely Cause Suggested Action
M1 and M2

Contamination in the optical cell may effect the accuracy of
readings and can trigger an information message to be displayed.
Clean optical windows gently with a soft, non-abrasive cloth
dampened with water or anti-static foam cleaner. Do not use solvents.
Instrument failure due to contamination is not covered by warranty.

Using Check Standards
Why is Percentage Transmission of Light being measured
with Lumiso Check Standards?
Lumiso works by measuring the amount of light that passes
through the sample. This value is known as the “Percentage
Transmission” or “%T”. Lumiso’s software then converts this
%T value into a concentration, such as mg/L of chlorine.
So, to verify that the instrument is within calibration it is only
necessary to check that the instrument correctly measures
%T for each wavelength of light it uses. This simplifies the
process for using check standards.
Check Standards can be purchased separately for your
Lumiso instrument. These standards contain Neutral
Density Filters (NDFs) and can be used to verify that the
instrument is within calibration
and performing correctly.

The wavelength(s) of light the
instrument uses are shown
in nanometres (nm).
While some Lumiso instruments
use more than one wavelength,
the Chlorine, Chlorine Dioxide
and Ozone instruments all use
only this wavelength.
If nothing is shown here, it is
because Lumiso has not been
“blanked” on the wavelength
highlighted.
