The display is only ever operated in a 4 ... 20 mA current
loop. A direct connection to a voltage supply (e.g. DC 24 V)
will lead to the display being damaged and will invalidate
the warranty.

mA source (e.g. mA transmitter or calibrator).
In normal operation, the display is connected in series with
a 4 ... 20 mA transmitter or connected to the 4 ... 20 mA
