4.9.3 Flow Calibration – PC
For this function the user will require the Impact Configuration
Utility (ICU) PC software, serial cable, Base Station and Power
supply. These items can be purchased as part of the
DataLogging kit (available separately).
Place the Impact into the basestation and ensure that there is
power connected. Switch the Impact on, and then follow the
instructions on the computer.
The instrument will display the readings whilst the calibration
process is occurring and the symbol will be displayed in the
centre of the display.
The software is designed to be easy to use and has its own
manual and online help.
