Saved jobs

Works offline once downloaded. Jobs are saved in this browser on this device. Browser storage can be cleared, so export a backup after every job.

G1 • Completion record

A working record based on common BS 7909 G1 information fields, not an official copyrighted certificate. Verify it against the edition of BS 7909 and the forms required by your client. No automated compliance certification is performed.

G2 • Schedule of test results

Add any number of circuits. Leave untested fields blank; do not substitute assumed results. Record protective-device details and measurements as observed.

Test comparison & revision history

Compare the latest readings with a saved revision. Differences are numerical changes, not pass/fail judgements.

Google Drive job folders

Google Drive requires an internet connection, HTTPS hosting and a Google OAuth Web Client ID. Offline edits remain on this device and sync only when the app is open, online and authorised. Do not treat Drive as your only backup.

Not connected

Each job is saved in a folder named after the job, under “BS7909 Field Records”. The folder contains the editable job JSON, circuit CSV, and a printable HTML record. PDF still requires Print / Save PDF and manual upload; automatic PDF upload is not supported in this version.

Export & handover

Your BH logo is embedded in the app and appears on the printable G1, G2 and circuit history records, including the Google Drive printable HTML export.

Use Print / Save PDF to open your phone's print dialog. On iPhone, use Share → Print, expand the print preview, then Share → Save to Files to save a PDF.

Before signing off, verify continuity, polarity, insulation resistance, earthing, protective-device selection, fault protection, RCD operation and all applicable BS 7909 requirements. A measured PSC/PFC or Zs is not by itself a pass/fail decision. This app deliberately does not mark circuits compliant automatically.
