  Suggested limits. A person must confirm every limit before this device can be written.
  Drafted with the driver writer from the MT-SICS command list in Mettler Toledo's reference manual
  30014405C for standard and advanced level laboratory balances (MS-TS, ML-T, ME-T). Readings assume the
  host unit is grams. The balance's RS-232 port defaults to 9600 baud, 8 data bits, no parity and 1 stop bit.
