1. FOREWORD
Solar meter: a device used to measure solar power.
From the moment you buy such a product, your future
is not uncertain any more. When the sun shines
recklessly, just take the TM-207 and aim its opening at
the sun, and you will see how powerful the sun is. If
you want your skin white, you surely cannot do without
it!
Measurement: Expressed by W/m2or BTU (ft2*h).
2. SAFETY PRECAUTIONS AND
PROCEDURES
This instrument conforms with safety Standard EN
61010-1 related to electronic measuring instruments.
For your own safety and to avoid damaging the
instrument follow the procedures described in this
instruction manual and read carefully all notes
preceded by this symbol.
CATION

When taking measurements:
Be particularly careful when measuring voltages
exceeding 20V to avoid risks of electrical shocks.
Avoid doing that in humid or wet places.
Avoid doing that in rooms where explosive gas,
combustible gas, steam or excessive dust is present.
Keep you insulated from the object under test.
Do not touch exposed metal parts such as test lead
ends, sockets, fixing objects, circuits etc.
Avoid doing that if you notice anomalous conditions
such as breakages, deformations, fractures,
leakages of battery liquid, blind display etc.
3. THE FOLLOWING SYMBOLS ARE USED:
CAUTION - refer to the instruction manual -
an improper use may damage the instrument
or its components

6.2.6.Auto Range button Large integrated circuit
design :
Press the “ ” power button to turn ON the
power and put the device to operating mode. If
“199.9” comes up on the screen, it suggests
the device will become overloaded or has become
overloaded “OL”. In this case, press the “ ”
button, and “1999” or your acquired value then
comes up.
6.3. TEST PROCEDURE
Press the ZERO adjustment.for the zero
adjustment if any digits is appear
If performing the zero adjustment after powering on,
several digits may not disappear. In this case,
perform the zero adjustment again.
Measure your car’s headlights:
Turn ON your car’s headlights. Then turn ON the
TM-207 solar meter, and “00.0” appears on the
screen. Put the device down close to the headlights.

Switch between high beam and low beam, and light
intensity values appear on the screen. Both the
right and left headlights must be tested. Note the
values and put them in your car for reference.
(Picture 2)
Measure the effect of solar insulation of your
vehicle’s windows:
Press the “ ” button to turn ON the TM-207
solar meter, “00.0” appears on the screen. Aim the
device at the sun and close to a window, and the
intensity appears on the screen. Open the window
and aim the device at the sun. Compare the value
against that acquired when the window is closed to
understand the efficiency of the window’s solar film.
Test your new car and preserve the measurements
in it. After that, test it at least once every year.

NOTE：When the light sensor cover is not attached
“CAP” is indicated. Make sure that it is attached. If
performing the zero adjustment after powering on,
several digits may not disappear. In this case,
perform the zero adjustment again.
