Important notes
- Confirm the measurement grid method, task plane, instrument, and site conditions before using readings as evidence.
- This tool generates a planning grid only and does not declare compliance with AS/NZS 1680 or AS/NZS 2293.
Formulas
- \(\displaystyle S_x = \frac{L - 2O}{2},\quad S_y = \frac{W - 2O}{2}\)
- A 3x3 grid is a measurement aid; the applicable project method remains external to this calculator.
Generate a simple 3×3 lux measurement grid for a small rectangular room with an explicit boundary offset.
3×3 Lux Measurement Grid Planner is a planning aid. Keep the target source, product data, measurement method, and project assumptions with the result. Confirm compliance, installation, certification, and safety decisions with the responsible professional.
FAQs
Is this 3x3 grid a standard rule?
No. It is a repeatable measurement aid for early records. Select and document the actual project measurement method separately.
