8.5 Input 1 Calibration Procedure
Preliminary Steps
• Apply power and allow the controller to warm up for 30 minutes before you calibrate.
• Please read Subsection 8.4 – Input 1 Set Up Wiring before beginning the procedure.
• Make sure you have LOCK set to NONE. See Subsection 4.5 - Tuning Set Up
Group.
• See Table 8-1 for Voltage vs. Resistance equivalents or 0 % and 100 % range values.
CAUTION
For linear inputs, avoid step changes in inputs. Vary smoothly from initial value to final 100 % value.
