| Measurement Range | 0 to 1280 W/m2 |
| Spectral Range | 300 to 1100 nm |
| Accuracy | Typically within ±10 W/m2 or ±5%, whichever is greater in sunlight; Additional temperature induced error ±0.38 W/m2/°C from 25°C (0.21 W/m2/°F from 77°F) |
| Angular Accuracy | Cosine corrected 0 to 80 degrees from vertical (see Plot B); Azimuth Error <±2% error at 45 degrees from vertical, 360 degree rotation |
| Resolution | 1.25 W/m2 |
| Drift | <±2% per year |
| Operating Temperature Range | -25° to 60°C (-13° to 140°F) with rechargeable batteries -40 to 70°C (-40 to 158°F) with lithium batteries |
| Radio Power | 12.6 mW (+11 dBm) non-adjustable |
| Transmission Range | Reliable connection to 457.2 m (1,500 ft) line of sight at 1.8 m (6 ft) high Reliable connection to 609.6 m (2,000 ft) line of sight at 3 m (10 ft) high |
| Wireless Data Standard | IEEE 802.15.4 |
