Clean the window area being tested.
Dirty glass can affect the accuracy of
your results.
Place both units of the instrument
together, back-to-back, with no glass
between them. Allow the magnets to
help align the two units, and then turn
the power on.
Wait for the instrument to register a
value of 100% on the display, and then
pull the two instrument halves apart.
Place the reflector unit on the inside of
the window being tested. Push the
reflector enclosure FIRMLY against the
window so the suction cups secure the
enclosure in place.
Place the instrument unit on the exterior
of the window being tested. Again allow
the magnets to help align the two
instrument halves.
Once the instrument unit is in position,
momentarily press and release the
power switch to view the Light
Transmission results (VLT value).
After registering the VLT value, remove
the instrument from the window and it
will automatically power off, clearing
your VLT value from the display after a
short delay. Repeat the process from
Step 1 if you would like to confirm the
a c c u r a c y o f y o u r p r e v i o u s
measurement.
OPERATING TIPS
Make sure the two enclosures fit
together properly when you begin.
The edges of the suction cups should
not be bent or altered in any way. You
will notice the felt pads on the back
of the enclosures are contoured so they
do not touch the suction cups when
the two enclosure halves are placed
together properly.
When testing the rear window of automobiles, take notice of the defrost
lines that are printed on the interior of the window. Suctions cups will NOT
stick if they are positioned on the defrost lines. If you can not find a location
where both suction cups will miss the defrost lines, rotate the reflector unit
90 degrees to position both suction cups in between the lines.
When your instrument is not being used, please store it in the carrying case
that was included. This will protect the product and keep it from getting
damaged or dirty while being stored. As with any test equipment, we do not
recommend storing the instrument in your automobile overnight during
extreme temperature seasons.
If at any time during the operation of the instrument you want to power the
unit off, press AND HOLD the power switch and the unit will shut off.
OPERATING TIPS . . . Continued
The reflector area must be properly maintained
in order for the instrument to continue providing
accurate results. Use compressed air to blow off
any dust that may accumulate over time. If there
are smudges on the reflector that can not be
removed by air, use a micro-fiber cloth to wipe
the lens clean.

TROUBLESHOOTING
Incorrect usage or the encounter of unexpected conditions while testing can
result in the following ERROR CODES:
E1:
The measured VLT value is
LESS THAN
the allowed percentage. The
E1 error may occur if the instrument is not properly aligned with the reflector
at start-up or during the actual measurement. It can also occur if you take a
measurement without placing it on glass, or are holding the instrument away
from the glass surface or in free air. To fix this problem, turn the instrument
off and make sure it is properly aligned with the reflector, with no glass in
between the two enclosures. Now turn the instrument on and conduct a
new test.
E2:
The measured VLT value is
GREATER THAN
the allowed percentage.
The E2 error may occur if the instrument is not properly aligned with the
reflector at start-up, or placed against a different surface other than the
reflector at start-up. To fix this problem, turn the instrument off and make
sure it is properly aligned with the reflector, with no glass in between the two
enclosure. Turn the instrument on and conduct a new test.
E3:
The starting value that was obtained on the reflector unit to calibrate the
device at 100% was different than expected. Make sure you properly align
the two enclosures at start-up. Also make sure the lens of the reflector is
clean. Use compressed air to blow off dust, or a micro-fiber cloth to remove
smudges.
