Select the channel to change. The highlighted channel
settings can then be altered using the s (increase) and
t (decrease) buttons, holding the buttons down to
change the setting more rapidly. Press 3 to store the
new settings value.
Assuming catalytic flammable is chosen the instrument will request which calibration
gas is being used, irrespective of what the instrument is set to measure.
The calibration gas screen for IR sensors will not display a gas selection as the IR
sensors are limited in the selection of flammable gases - See Special Notes for
IR Sensors on page 65.

4�9�3 Flow Calibration – PC
In addition to the items required for flow adaptor calibration (Section 4.9.2), 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 Base Station and ensure that the power supply and serial
cable are connected. Switch the Impact on, use Impact Configuration Utility (ICU)
software to perform calibration.
The instrument will display the readings while the calibration process is occurring
and the
symbol will be displayed in the center of the display.
Information, such as gas cylinder serial numbers, can also be entered for traceability.
Also, calibration reports can be printed.
