2. 4-20 mA Input Only - Select a 250Ω (for AIN#) or 3.75Ω (for AINU#)
resistor from the installation kit and insulate the bent resistor lead with a piece
of sleeving. At the lead end, approximately 1/4" (6 mm) to 5/16" (8 mm) of
bare resistor lead should be exposed.
If a crimp-on connector is to be used, go to step 3. Otherwise, go to step 4.
