ii. Apply a second known pressure, P
pressure, and record the measured pressure, P
P = Read COMP_PRES: COMP_PRES [31..0] <1 [31..0]>

iii. Read and record the current values G, O and C of the following configuration
data registers:
G = Read GAIN_ADJ: GAIN_ADJ [31..0] <68 [31..0]>
O = Read OFFSET_ADJ: OFFSET_ADJ [31..0] <69 [31..0]>
C = Read PRES_CONV: PRES_CONV [31..0] <83 [31..0]>
iv. Calculate the values S, G* and O* using the following formulae;
v. Unlock the configuration data registers as described in section 4.4.1.
vi. Update the following configuration registers:
Write the value of G* to GAIN_ADJ: GAIN_ADJ [31..0] <68 [31..0]>
Write the value of O* to OFFSET_ADJ: OFFSET_ADJ [31..0] <69 [31..0]>
vii. Save the new calibration zero and span factor values to non-volatile memory
if required and re-lock the configuration data registers as described in section
4.4.1.
The user may also record the date of re-calibration by modifying the date fields of
CAL_DATE register.
For example, to change the calibration date to 16
step between steps vi. and vii. above:
viii. Update the date field values.
Write 2015 to CAL_DATE: YEAR [15..0] <72 [31..16]>
Write 4 to CAL_DATE: MONTH [ 7..0] <72 [15..8]>
Write 16 to CAL_DATE: DAY [7..0] <72 [7..0]>

Maintenance

High pressures and extremes of temperature are dangerous. Be careful when
working on components of systems where high pressures and high or low
temperatures are present. Use all applicable protection measures and observe
all safety precautions.

Cleaning

The external version of the DPS 5000 sensors may be periodically cleaned if required
using a lint free cloth and a soft brush. If necessary, use a weak detergent solution
to moisten the cloth. Allow the sensor to dry before re-use.
Do not use cleaning agents, solvents or high-pressure gas to remove dirt as
these may damage the sensor.
