This practical guide shows you how to complete a signed, QR-verified Emergency Egress & Exit Lighting Test certificate in OhmCert Module #16 and how to troubleshoot non-compliant readings on site.

1. Step-by-Step OhmCert UI Workflow

  1. Open Module #16: Navigate to Emergency Egress & Exit Lighting Test from the Dashboard.
  2. Load a 1-Click Standard Annex Preset: Open the blue Standard Annex banner at the top and click a preset (such as "3-Hour Industrial / Commercial Escape Route (180 min)") to populate target limits automatically.
  3. Enter Your Field Measurements: Fill in the measured inputs (Measured Duration Test, Required Duration, Escape Route Illuminance (centre line), Open (Anti-Panic) Area Illuminance, High Risk Task Area Illuminance, Normal Lighting Level at Task, Maximum Illuminance on Route, Minimum Illuminance on Route, Time to Reach Full Rated Output). Blank inputs stay neutral PENDING.
  4. Complete the 13-Point Checklist: Grade each item, attach photos if needed, and export the SHA-256 signed PDF certificate.

2. Worked Numerical Field Case Study

Scenario: 3-Hour Industrial / Commercial Escape Route (180 min) (EN 1838 / BS 5266-1) — Standard 3 h duration test with 400 lx normal task illuminance..

  • Required Duration: 180 min
  • Normal Lighting Level at Task: 400 Lux

3. Engineering Troubleshooting: Corrective Actions When a Reading Fails

  1. Replace NiCd / NiMH / LiFePO4 battery packs in self-contained luminaires that extinguish before the 180-minute / 60-minute threshold.
  2. Add twin-spot or corridor-lens emergency fittings at dark zones where E_min drops below 1.0 lux or E_max / E_min exceeds 40:1.
  3. Replace obsolete text-only exit signs with ISO 7010 running-man pictograms sized for viewing distance D.
