Guides
All guides- GPS-stamped test results: proof you were at the board
Optionally stamp every reading with GPS at the moment of capture — resolved to a street address, linked to a map, and printed on the report only when you choose.
- Test & tag labels that verify themselves: Bluetooth printing + QR scan-back
Print durable test tags on a Zebra Bluetooth label printer at the board — each with a QR code that clients can scan to verify the test, and you can scan to recall the full record.
- From paper test sheets to portal-ready: retiring the triple-entry
State portals like eCert and ESVConnect are mandatory — the clipboard and spreadsheet in the middle aren't. How one validated capture feeds the client report and the certificate fields.
- Field Efficient vs electrical calculator apps: different tools, different jobs
Calculator apps check the maths before the work; Field Efficient proves the work after it — capture, AS/NZS validation, reporting and state certificate prep.
- Field Efficient vs job-management apps: do you need both?
Job-management apps run the business — scheduling, quoting, invoicing. Where they stop at blank compliance forms, a dedicated testing app takes over. An honest comparison.
- Australian electrical certificates by state: what to lodge, where, and when
NSW CCEW, VIC COES, QLD Certificate of Testing & Compliance, SA eCoC and WA eNotice — the certificate, the portal and the deadline for each mainland state, verified against the regulators.
- AS/NZS 3000 verification: the tests every installation needs
The mandatory verification tests AS/NZS 3000 requires before a new installation is energised — in order, dead before live — and what goes on the report.
- Test & tag intervals: the AS/NZS 3760 schedule (Australia)
How often electrical equipment must be tested and tagged under AS/NZS 3760, by environment — plus what the test involves and what goes on the tag.
