Channel 2 now behaves like this:
- Clipping is now set to 10%, meaning the output is allowed to vary
between 0.6 ... 5.4 V. The channel will output the measurement for
-11 ... 61 °C, but range 1 ... 5 V remains scaled to show -5 ... 55 °C.
- Error limit is 20%, which means channel 2 will show the error state
(6 V) when the measured value is 20% outside the scaled output
range. With the settings above, this will happen if the measured
temperature is outside range -17 ... 67 °C.
- The output will never actually be between 5.4 and 6.0 V because of
clipping.

Select Parameters to Display
Use the DSEL command to select the parameters that are displayed on
the transmitter screen. You can select parameters by abbreviation, or
select same parameters as are assigned to the analog outputs. If only one
parameter is selected, it is shown vertically centered on the transmitter
screen.

Q2 = Second parameter to show on the screen. Available
parameters are the same as for Q1.
Q3 = Third parameter to show on the screen. Available parameters
are the same as for Q1.
