Pulse and Digital Input Calibration
Overview
Totalflow XRC comes standard with 2 high speed Pulse Inputs on board.
These may also be used as Digital Inputs. The following procedure is for
calibrating Pulse Inputs. As you enter the calibration screen and have
selected the P/I that you would like to calibrate, the XRC enters the Hold
Mode and displays the current values and their register number.
The Current Values section will display the current values continuously by
checking the "Update" box. When different pulse inputs are selected, their
assigned register numbers are displayed on the top of the screen.
Follow the instructions in the PCCU32 Help files for specific software steps.
Generally you need to complete the following procedure.
Instructions
Step Procedure
1.
Click on the K-Factor button, enter a value and click the OK button.
Input pulses are multiplied by the K-Factor. To have a one to one
pulse count, use a factor of 1.
Please take into consideration that these inputs may have the DeBounce
enabled or disabled. This feature is discussed in detail in Chapter 1 On-
Board Input/Output section. Look at Jumpers J5, J11, J9 and J12 on the
XRC-195 Board.
