# scenario: poll on a V10 mass-flow *meter* (MW-10SLPM-D, 10v04.0-R24)
# Captured 2026-04-17 from /dev/ttyUSB0 (Prolific PL2303, 19200 baud).
#
# Field order matches dataframe_format_meter_v10.txt:
#   Unit_ID  Abs Press   Flow Temp   Volu Flow   Mass Flow   Gas
#   A        +14.633     +022.97     -00.034     -00.034     Air
#
# Notes:
#   - 5 required fields (no Mass_Flow_Setpt — this is a meter).
#   - Negative Volu/Mass Flow values reflect zero-flow noise (device is
#     idle on the bench); the parser must accept signed decimals here.
#   - Width/precision is `7/3` (3 decimal places) — see notes in
#     dataframe_format_meter_v10.txt.
