3. Set the Transducer Minimum and Maximum Range values.
4. Select “Program SIO” from the SIO dropdown menu.
5. Select “Signal Conditioning” from the dropdown menu.
6. On the Signal Conditioning screen, Figure B5, select the
“Programmable Gain” value that is closest to the ideal gain
without exceeding it. Then click the “Configure” button.
The “Configure” button downloads the settings to the SIO without
writing them into flash memory.
7. Short the SIO signal inputs. Set the “PreGain Null” voltage so the
Node voltage, displayed at the bottom of the dialog, is as close to
the offset voltage as possible. Then click the “Configure” button.
Note that the PreGain Null settings are very coarse, so the
resulting Node voltage may not be close to the desired setting.
8. Remove the short and attach the sensor to the SIO. Set the
“PostGain Null” voltage so the Node voltage is as close to the
offset voltage as possible, then click the “Configure” button.
