TRACK Setting the pressure tracking mode on/off

TRACK <cr>

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 <cr>

Min/max track.: OFF

>track on <cr>

Min/max track.: ON

>track off <cr>

Min/max track.: OFF

PLIM Pressure limit listing

PLIM <cr>

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.
