When configuring your instrument, select
Process Type
in the Input Type Menu
(see
Part 3
).
2.3.5 Process Voltage
The figure below shows the wiring hookup for Process Voltage 0 – 100 mV,
0 – 1 V, 0 – 10 V.

R
L
-
Voltage limited resistor, which allows to convert 24 Vdc internal excitation
voltage to the appropriate process input value. For instance: if the potentiometer
value is equal to 10 kΩ, the minimum R
L
is 14 kΩ for 10 V process input.
When configuring your instrument, select
