4.6 Pressure and Elevation
Note: If the barometric pressure from Table 5 is entered in the meter, the altitude entered in
combination with this value must be 0 feet.
Table 5 can be used to estimate the true barometric pressure at certain elevations. The
correspondence is based on the assumption that at sea level the barometric pressure is
760 mm Hg. After determining the barometric pressure from the table or obtaining it from a
local weather service, enter this value into the instrument.
DIAG/TEST
PROBE INFO
Display the entered name of the sensor, the sensor serial number, the software version number, and the sensor driver
version number.
CAL DATA
Displays the current offset correction and the date of the last calibration.
SIGNALS
SENSOR SIGNAL allows the user to set the sensor range and display the sensor ADC counts and TEMP ADC COUNTS
shows raw data for temperature ADC counts. Comparable to A/D counts.
COUNTERS
SENSOR DAYS displays the cumulative days the sensor has been in use and RESET SENSOR allows the sensor counter
to be reset to zero.
