TRACK Setting the pressure tracking mode on/off
TRACK
The TRACK command is used to activate or deactivate the minimum/
maximum pressure tracking mode of the barometer. When activated,
the barometer stores in memory the minimum and maximum pressure
values measured. At power-up the tracking mode is always
deactivated.
The serial interface and the local display of the PTB220 series
barometers have separate tracking modes. The serial interface TRACK
command will not cause pressure tracking limits to be displayed by
the local display of the barometer. Activating the display tracking
mode will not activate the pressure tracking mode of the serial
interface.
Example:
>track
Min/max track.:
OFF
>track on
Min/max track.:
ON
>track off
Min/max track.:
OFF
>
PLIM Pressure limit listing
PLIM
The PLIM command is used to list the indicator level of pressure
stability, the minimum/maximum pressure tracking levels and the
pressure high alarm and low alarm levels. If the minimum/maximum
tracking mode is deactivated, only OFF is output instead of the
pressure readings.
