The Digital "SOLAR TRANSMISSION & POWER METER" incorporates two meters into
one. In Power Mode, the meter measures the power per unit area of incident solar
radiation reaching the meter's sensing area. In Transmission Mode, the SP2065 is
able to calculate the solar transmission percentage associated with a given
material. The meter uses a state-of-the-art sensor coupled with microprocessor
control to achieve an EASY TO READ hand-held meter. The device may be used to
measure the solar characteristics of windows, film or other transparent materials.

SP2065 WARRANTY
The manufacturer warrants all models of the SP2065 to be free from defects in material and
workmanship under normal use and service as specified within the operator's manual. The
manufacturer shall repair or replace the unit within six (6) months from the original date of
shipment after the unit is returned to the manufacturers factory, prepaid by the user, and
the unit is disclosed to the manufacturers satisfaction, to be thus defective. This warranty
shall not apply to any unit that has been repaired or altered other than by the
manufacturer. The aforementioned provisions do not extend the original warranty period
of the unit which has been repaired or replaced by the manufacturer. Batteries are not
covered by warranty as well as damage caused by over-heating the device.
The manufacturer assumes no liability for the consequential damages of any kind through
the use or misuse of the SP2065 product by the purchaser or others. No other obligations or
liabilities are expressed or implied. All damage or liability claims will be limited to an amount
equal to the sale price of the SP2065.

BATTERY REPLACEMENT
CALIBRATION
The SP2065 is powered by a 9 volt battery. When the battery voltage is getting too
low to operate the meter, the display will begin blinking. Once the display begins
blinking you will want to replace the battery soon. To replace the battery, turn off the
power meter. Remove the battery cover near the bottom of the meter and
replace with a new battery. Alkaline batteries will provide the longest service, but
are not required for this product.
This instrument has been calibrated to detect the total incident solar power of the sun.
The largest incident value of solar power is obtained when the end of the meter faces
the sun directly. When the end of the meter does not face the sun, the incident solar
power is reduced by the cosine curve of the angle to the sun. Make sure the
transparent materials being tested are reasonably clean.
This instrument is factory calibrated to a NIST (NATIONAL INSTITUTE OF STANDARDS AND
TECHNOLOGY) traceable thermopile and should require no field adjustment.

UNIT OF MEASURE
INDICATOR LEDS
1. If taking measurements near a heat lamp, do not place the meter too close to the
light source. If the end of the meter begins to feel hot to the touch, it is too close to the
light source. Extended periods of heat exposure can cause deformation of the filters,
resulting in a change in the accuracy of the meter. It is recommended that the heat
lamp and meter are separated by at least 18 inches (46 cm).
2. When taking measurements for transmission percentage or comparative tests, it is
important that the meter is held in the exact same position for both measurements
(when possible). Any change in angle or proximity to your light source can adversely
affect the accuracy of your measurements. FOR BEST RESULTS, place the meter
on top
of a stand (#SP2075). It is best to leave the heat lamp and meter stationary, while
sliding the glass sample in between them. This will guarantee the most accurate
measurements possible.
3. When performing tests, it is advised to take multiple readings to reduce the amount of
error that occurs. Be aware that a changing light source (sun with moving clouds) will
affect your measurements.
4. The light sensor is located at the top end of the enclosure. For the greatest accuracy
in measurements, this sensor should be directly facing the light source. DO NOT alter the
condition of the sensor opening by touching or pushing on the filter. Any modifications
or altering of the exterior surface of the white filter WILL affect the calibration of the meter.
This area should be kept clean at all times. Compressed air or a lint-free cloth should be
used to clean the filter surface if it becomes soiled.
5. Do not attempt to open the enclosure. Opening the enclosure will void the product
warranty and affect the calibration of the SP2065 meter.
