300 L/min meter air and nitrogen meter can output either air or
nitrogen signals.
20 L/min air, nitrous oxide and nitrogen meters output air, nitrous
oxide and nitrogen signals.
Both 300 L/min and 20 L/min oxygen meter can only output oxygen
signal.
After the command is processed, an acknowledge sequence of “OK”
<CR> <LF> is sent. If the command generated an error instead of
“OK” <CR> <LF> being sent, an error code of “ERRn” <CR> <LF> will
be sent. See the end of this section for a list of possible error codes.
Use the SAVE command to permanently store the selected gas
calibration as the new power-on default.
Example 1) SG0 Sets the gas calibration to air.
