  • Veris E50 (E50C2 full data set; E50C3 adds data logging).
  • Pulse counter 1 and 2 weights come from the energy-per-pulse setting (register 144). Registers 257 and 259 are both labelled real energy in the manual; the second is probably a duplicate listing.
  • Addresses follow the manual's numbering, which starts at 1 (address_base 1). 32-bit values and floats have the most significant register first.
  • Integer registers hold the value as an integer; the engineering value is the raw value times 10 to the power in the matching scale factor register (current, voltage, power, energy). Float registers need no scaling. Values the meter does not support in the chosen system type read as 0x8000 (integers) or NaN (floats).
  • The meter answers on both FC03 and FC04; the map lists the registers as holding.
