Setra System Model 370 - Manual (Page 14)

3.4 CONVERTING ENGINEERING UNITS
The Model 370 will measure pressure in any engineering units, including six
built-in pressure conversions, two built-in altitude conversions, and a
user definable conversion.
To convert from one unit to another, simply press the CONV key repeatedly
until the units you want are in the display. The order of units is as follows:
hPa - PSI - mbar - mmHg - inHg - mmH2O - inH2O - ft - m - units. To return
directly to the units the gauge was calibrated in, press "-" then CONV.
See Section 4.1 for instructions on the use of user-defined units ("units"),
or Section 5 for displaying altitude.
3.5 TRACKING MIN AND MAX VALUES
To use the Model 370 to track the minimum and maximum pressures applied to
the sensor, enter the tracking mode by pressing SETUP, then MIN/MAX.
To examine the values stored, press MIN/MAX. The gauge will display "HI"
and the maximum value encountered for about three seconds, then will
display "LO" and the minimum value encountered for about three seconds,
and then will revert to normal display.
To shut off the min/max tracking mode, press "-", then MIN/MAX.
If the MIN/MAX key is pressed without having first entered the MIN/MAX
tracking mode as described above, the display will read "UnAbLE". Press
CLEAR and then follow the above procedure.
