DISCLAIMER This is a consumer application designed for general audio analysis and educational purposes. It is not a certified measurement instrument and should not be used where legally compliant or certified measurements are required. For professional acoustic assessments requiring traceable calibration or regulatory compliance, we recommend using an external calibrated measurement microphone with certified sound level meters.

The register decoder that lives in your pocket — and never phones home. You're at a panel with a flow meter publishing FLOAT32 and a SCADA tag that reads garbage. FieldReg decodes 1, 2, or 4 Modbus registers into every interpretation simultaneously — signed and unsigned integers, FLOAT32/64 — in all four byte orders (ABCD, CDAB, BADC, DCBA), with a plausibility flag that points at the value that makes physical sense. Decode — hex or decimal entry, smart paste, swap word order in one tap, automatic history. Address — protocol address ↔ 1-based ↔ 40001 ↔ 400001, with read/write function codes per entity. Scale — linear scaling, 4–20 mA loop calculator with NAMUR range flags, 0/25/50/75/100 % injection tables you can export as CSV straight into the loop-check record. Save instrument presets. Bits & CRC — tappable 16-bit grid, hex/decimal/binary/octal live, CRC-16/MODBUS with the on-wire byte order spelled out. Reference — eight offline field sheets: function codes, exception codes, RTU/TCP framing, RS-485 wiring, serial gotchas, data types, PLC addressing, 4–20 mA. 100 % offline. No account. No analytics. No tracking. Your register values never leave the device — the App Store privacy label reads "Data Not Collected" because nothing is. Free forever: 16-bit decode, FLOAT32 in all four orders, and the address converter. One affordable one-time purchase unlocks the rest — no subscription. Made by a controls engineer, for the people standing in front of the panel. — Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://aphelionengineering.com.au/fieldreg/privacy/
