 "summary": "The PowerScout 3037 is a compact three-phase submeter with CT inputs, an RS-485 port (Modbus RTU or BACnet MS/TP) and an optional Ethernet port. In Modbus mode everything is a holding register read with function 03. Readings are 16-bit unsigned integers whose scaling depends on a user-set data scalar (44602). This map covers identification, the main system and per-phase readings, line frequency, and the CT, scaling, wiring, pulse-output and comms settings.",

So wire address = printed register - 40001, which equals the printed offset."

 "notes": [
  "Scaling: the guide's scalar table (p. 34, Table 7) applies to registers 44001-44061. Those integer readings are listed here raw (scale 1, no unit); multiply by the factor for the current Data Scalar (44602, values 0-6, see its value list) in the column named in each register's description: kW/kWh/Demand, kVAR/kVARh, kVA/kVAh, Amps or Volts. Power factor is x0.01 at every scalar, so the PF registers carry that fixed scale.",
  "Two-register integers (energy, time since reset) put the LSW at the lower register and the MSW at the next one; the guide's worked example (p. 36) computes MSW x 65536 + LSW, then applies the scalar. They are listed as UINT32 with CDAB word order.",
  "The guide says every register is a 16-bit unsigned value (p. 81), yet its positive/negative PF register descriptions refer to the system and phase PF values in 44014/44015/44050-44055 being negative. How a negative PF is encoded there is not stated; they are listed as unsigned here.",
  "Left out: the positive (46xxx), negative (47xxx) and NET (44150-44157, 46150-46157, 47150-47157) power and energy blocks. The guide's scalar table names only registers 44001-44061 and does not say which factor applies to these blocks. The exception is 46022, which the guide documents as 10 x Hz.",
  "Left out: the Veris H8035/H8036 floating-point block 40257-40310 (Table 27). The guide labels each value MSW/LSW but never states the float format, gives units only by name, and does not say whether the block answers when 44526 is not set to 1 (Veris identity).",
  "Left out: the Veris integer block 40001-40027. Its multipliers depend on the CT rating band (Table 26) rather than a fixed scale.",
  "Left out: 44022 Line Frequency (the absolute block gives no scale); use 46022.",
  "Left out: per-CT settings 50100-50399, the CT phase-shift registers, the snap-to-zero thresholds and the synchronize register 40129, as their encodings are not fully stated.",
  "Left out for size: the per-phase energy, kVAR, kVA and displacement-PF registers and the extra demand registers 44080-44084 (see pp. 67-70).",
  "DENT's one-page 'Interpreting the PowerScout Registers - Data Scaling' sheet (https://www.dentinstruments.com/wp-content/uploads/2022/09/Interpreting_PowerScout_Registers_Data_Scaling.pdf) gives the same scalar table, but its worked examples name registers 44302 and 44064 as the scalar register; in the guide 44064 is the Data Tick Counter. The guide's 44602 is followed here."
