Model SLR-01 Handheld Solar Power Meter measures the solar
energy to determine the appropriate position or location for solar panels.
It can be used to test the performance of solar receivers and solar
window treatments. Using the end-mount light sensor, the meter is able
to read and display in units of W/m2and BTU/(ft2*h). The large numbers
and high contrast of the LCD make it easy to read the measurement,
even in bright areas. Applications include solar farms, office buildings that
utilize energy harvesting sensors, and telemetry systems.
SPECIFICATIONS:
Range: 0 to 1999 W/m2; 0 to 634 BTU/(ft2*h).
Accuracy: ±10 W/m2; ±3 BTU/(ft2*h) or ±5%, whichever is greater;
Additional temperature induced error above 77°F (25°C) ±0.38 W/m2,
±0.12 BTU/(ft2*h) per °C.
Display: 3-1/2 digit LCD.
Resolution: 0.1 W/m2; 0.1 BTU/(ft2*h).
Temperature Limits:
Operating: 41 to 104°F (5 to 40°C);
PRODUCT OVERVIEW

OPERATION
1. Press the power button to turn the power on.
2. Place the light sensor at the spot where the meter can test the source
of light. After the reading becomes stable, the result will then be
displayed on the LCD.
3. After testing, press the power button again to turn the power off.
Note: When the meter is not in use, do not leave in direct sunlight to
prevent damage to the sensor. If the meter will not be in use for an
extended period of time, remove the battery before storing.
Changing Unit
To change the unit, press the Unit Switch button to toggle between the
units.
Data Hold
To keep the reading value on the LCD permanently after it has been
recorded, press the Data Hold button. The locked screen can be
released by pressing the Data Hold button again.
Maximum/Minimum
To view the maximum or minimum recorded values, press the Max/Min
button. The maximum value will be shown on the first press of the button
and the minimum value will be shown on the second press. Press and
hold the button to return to recording mode.
Auto Ranging
To change the placement of the decimal point, press the Auto Range
button. This will cause the meter to change the decimal point position
based on the levels of light it is reading.
Note: In the case of the meter being overloaded and displaying “OL” on
the LCD, press the Auto Range button and the acquired value will be
shown on the display.
BATTERY REPLACEMENT
When the battery symbol appears on the LCD, the battery needs to be
replaced. To change the battery, remove the cover to the battery
compartment and remove the battery currently in the instrument. Place
the new battery in and replace the cover.
MAINTENANCE/REPAIR
Upon final installation of the Model SLR-01, no routine maintenance is
required. The Model SLR-01 is not field serviceable and should be
returned if repair is needed. Field repair should not be attempted and
may void warranty.
