TintMan
Quick Reference Guide
Any material to be tested should be clean and free from grease, finger marks
and dust. If necessary the material should be cleaned using a propriety glass
cleaner and thoroughly dried using lint free cloth.
Before use always check and adjust the Tintman instrument sensitivity against the
sample of Reference Window supplied in the instrument kit. The Reference Window
is marked with the transmission measured by a reference instrument. Please refer to
the Checking and Adjusting Tintman instructions at the end of this guide.
To use the instrument connect the light source and detector to the readout unit
with the colour coded connectors. Check the colours match and the connectors
are pushed in firmly. The light source has a red connector, the detector black. No
damage will be done if the connectors are mistakenly swapped.
Attach the source and detector to either side of the material to be measured, if
necessary use the captive suckers to secure to vertical windows. The source and
detector should self align magnetically. On raked windscreens attach the detector
to the inside of the glass hanging from its sucker. When the source is placed on
the outside of the windscreen the magnetic attraction between the two should
automatically draw the detector to the windscreen.
Before taking a reading, visually check that the source and detector are
concentrically aligned and firmly against the material.
To take a transmission reading press the large button on the readout unit. The
display will show the measured transmission in percent. Allow about 10 to 20
seconds with the button depressed for the light source intensity to stabilise. Keep the
button pressed throughout this period. It is recommended that three readings are
taken at different positions and the average value used.

A low battery warning will appear on the display momentarily when the button is
depressed and then disappear. If the low battery warning remains on do not accept
the transmission reading and change the instruments batteries (four AA alkaline cells)
immediately.
If the transmission test is done in very bright direct sunlight, stray light scatter may
increase the apparent transmission by up to 0.5%.
Note that the high power magnets used in Tintman are brittle. Do not drop
them or bang them together. They will shatter. Do not force either of the
magnets against another magnetic pole of the same polarity - their strength
may be weakened!
Checking and Adjusting Tintman
Before each use it is recommended that the sensitivity of the instrument is checked
against the Reference Window and the 100% Spacer Ring supplied in the kit.
The Reference Window is marked with the value of transmission measured by a
reference instrument.
The aim of this check and adjustment is to make sure Tintman reads the correct
transmission value. If the reading is low increase the sensitivity by turning the recessed
control clockwise with the tool provided. To decrease the sensitivity turn anti-clockwise.
Insert the 4 mm thick 100% Spacer Ring between the source and detector magnets
and adjust the sensitivity until the instrument reads 100.0± 0.3.
Make sure the Reference Window is clean, attach the source and detector and take
a normal reading. This reading should be within ±1.5 of the value printed on the
Reference Window. If not repeat the 100% adjustment.
If the readings fluctuate, clean the connector contacts by rotating the red connector
plug in its socket.
Do not place the source or detector near computer disks, the fields from
their magnets may corrupt the disk.
