What does this solar power meter measure?

It measures solar radiation (insolation) falling on a horizontal surface. The range is 0–1999 W/m² or 0–634 BTU/(ft²·h), with accuracy of ±10 W/m² and ±3 BTU/(ft²·h). It suits solar panel evaluation, meteorology, and environmental monitoring.

Can I switch between W/m² and BTU units?

Yes. The meter supports dual-unit switching between W/m² and BTU/(ft²·h) to match different testing requirements, making it easier to compare results across solar-energy and heat-radiation applications.

How does the MAX/MIN tracking function work?

Press the dedicated button to record the highest and lowest irradiance values during a session. This lets you observe changes in sunlight intensity over time without needing to watch the display continuously.

What is the manual zeroing feature and when should I use it?

Manual zeroing lets you set the correct baseline before taking a measurement. Press the zero-adjust control prior to testing to ensure accurate readings from the start. The clear digital display supports straightforward operation throughout.
