Calibrating Analog Outputs and Inputs 8-5
December 2003
Analog Inputs
The TransPort enables you to calibrate the analog inputs using a
temperature range or a 4 to 20-mA current. To calibrate the
temperature input, you need to connect a low and high
temperature reference (or calibrated current source) to the
temperature input connector shown in Figure 8-3 below.
Figure 8-3: Analog Input Connections
The calibration procedure consists of calibrating the low and high
inputs. Use the section that follows to properly calibrate the
TransPort.
Note: The two temperature inputs may be calibrated in any
order.
