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

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
