What does MeggerMind calculate?

MeggerMind calculates DAR, PI, corrected insulation resistance, IEEE 43 reference minimums, NETA reference minimums, verdicts, and trend projection from saved readings.

Does MeggerMind work without signal?

Yes. The verified build stores data locally and generates reports on device without a backend or account.

Offline Android field tool

MeggerMind

Q: Does MeggerMind measure resistance?

No. The user enters readings from a calibrated insulation resistance tester. The app calculates and records the result. It does not replace review by a licensed engineer or the authority having jurisdiction.

Save insulation resistance readings, calculate PI and DAR, apply IEEE 43 temperature correction, and export a standards-cited record before the job leaves the panel.

Built for timed megger tests.

MeggerMind keeps the field record with the asset, result, and export instead of leaving the calculation in a notebook margin.

PI Polarization index from 10-minute and 1-minute readings.

DAR Dielectric absorption ratio from 60-second and 30-second readings.

40 C IEEE 43 temperature correction reference point.

PDF Single-test and asset-history exports for QA records.

From reading to record in one flow.

Enter the timed readings from a calibrated insulation resistance tester. MeggerMind computes the result, stores the asset history locally, and prepares the export for the share target you choose.

Asset memory for motors, feeders, cables, and switchgear.
Voltage class and insulation class context for reference thresholds.
Trend projection when repeated readings show drift.
CSV export for spreadsheet review and PDF export for job records.

MeggerMind pass result screen showing DAR, PI, corrected resistance, and export actions.

No account, no cloud dependency.

The verified Android build stores data locally and does not declare the Android Internet permission.

Local SQLite storage

Assets, readings, drafts, archive state, and settings stay in app-private storage on the device.

Standards-cited output

Reports include calculation detail, reference thresholds, and field-reference scope language for handoff.

Offline exports

PDF, CSV, and summary-text export paths work without a server or sign-in.

Privacy scope

Your test records stay on your Android device.

No account system.
No analytics SDK.
No advertising SDK.
No tracking SDK.
No cloud sync.
Data leaves the device only when you choose to share an export through Android.

Field questions.

Does MeggerMind measure resistance?

No. Enter readings from a calibrated insulation resistance tester. MeggerMind calculates and records the result. It does not replace review by a licensed engineer or the authority having jurisdiction.

What standards does it reference?

The app includes IEEE 43-2013 temperature correction and NETA ATS-2021 reference threshold context.

Does it work without signal?

Yes. Core entry, saved history, PDF export, CSV export, archive, settings, and delete-all-local-data are local.
