Current units are <Units> (<unit number>)<CR>
<CR>
Note: mbar can be selected using codes 0, 21 or 24.
Result: Each of these non-volatile commands changes the pressure units of the
transmitted reading.
Query: <SPACE>*U,?<CR>
Reply: Units = <Unit number><CR>
6.7 PIN Protected Set-up Commands
Note: PIN protected set-up commands are not available on USB models.
6.7.1 C - User Calibration
This command allows the user to perform a two point calibration on the output of the device. The
calibration routine requires two pressures to be applied within the operating extremes and in units
of pressure measurement set in the transducer. The software calculates an offset and gain
correction to all subsequent readings.
Command: <SPACE>C<CR> or <SPACE>*C<CR>
