2. Choose the CONFIGURE menu and then the SENSOR CALIBRATION menu;
3. Enter the administrator's access code (password);
4. Pay attention to the message "FOLLOW INSTRUCTIONS"; refer to the manual;
5. Press on the message area to open the calibration page;
6. Select the calibration menu "Relative pressure";

A. , with full scale of the test
pressure; resolution at least 0.1 mbar, accuracy 0.2% FS.
B. Pressure source, capable of generating full scale pressure; may be a precision
pressure regulator, but a manual pump with micrometer regulator and pres-
sure relief valve is preferable.
Pressure generation with external source or internal valves.
Initially, when entering the calibration procedure, the internal valves are closed,
so the test pressure can only be generated from an external source; but if the
external source is not available, the operator can open the internal valves and
generate the test pressure with the electronic pressure regulator, inside the
equipment.
On the gain calibration page, where it is necessary to generate the test pres-
sure, there are some [+/-%] keys that the operator can use to adjust the pres-
sure.
Press a key [+% ] to open the internal valves, then adjust the pressure with the
keys [+/- %]; if a key [-%] is pressed until the pressure regulator is reset to zero,
the internal valves close again.
The digital pressure gauge is used as a reference sample.

Reading
To verify the calibration of the instrument, change the pressure with the external
source and compare the pressure measurement of the instrument with the meas-
urement of the digital reference standard pressure gauge (the [+/-%] keys are not
enabled on this page).
Carry out the check over the entire pressure measuring range, at regular intervals,
upwards from zero to full scale, then downwards from full scale to zero.
Choose zero or gain calibration (GAIN).
