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 SP2080 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
controltoachieveanEASYTOREADhand-heldmeter. Thedevicemaybeusedto

CALIBRATION
The SP2080 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

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
arenotrequiredforthisproduct.
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

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
lampandmeterareseparatedbyatleast18inches(46cm).
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
measurementspossible.
