Data log readout on 4 to 20ma input

I have two 4 to 20ma transducers to give me up/down hydraulic pressure on my Glasair II RG, switched via a latching relay, to provide a pressure readout on one widget on the EMS.  The EMS presentation shows the actual pressure (about 1700psi) when the gear is up.  However, when I download data the hydraulic pressure reading does not go above 999psi.  Is there a setting which can be changed to show the actual pressure above 999psi?

There is not a setting that will allow this to be datalogged fully.

Because of the structure of the datalog, we had to pick a fixed number of digits for each "function" of sensor. PSI only goes up to 3 digits.

Your only real option here is to re-do the sensor calibration to show PSI in 10s of PSI, so you'd get 170 for 1700 PSI and 92 for 920 PSI. This would show on the SkyView screen the same way.
