CALIBRATION COMMANDS
COMMAND FUNCTION
OFFS? ENERAC returns a list of voltage offsets for each sensor.
FACT? ENERAC returns a list of calibration factors for each sensor.
SPAN XX NNN ENERAC span calibrates sensor XX at a span value of NNN
PPM or percent. Be sure to feed the correct span gas and wait for
the sensor to stabilize before the analyzer receives this command,
as it will execute a span calibration immediately.
