R
L
- Voltage limiting resistor, which allows conversion of the 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 Process Type in the Input Type Menu (see Part 3).
