3.0 Part descriptions
Read the following part summaries before beginning calibration setup.
3.1 ALCOSIM breath alcohol simulator
The simulator calibration method uses a known water alcohol solution to produce an air to alcohol vapour. To simulate the
human breath, this vapour is thermostatically maintained at a constant temperature of 34°C. The result is an accurate method
of recreating a known breath alcohol concentration (BrAC).
3.2 Calibration Station (CS)
The CS provides the air supply to the ALCOSIM simulator, and logs the number of tests performed with each bottle of alcohol
reference solution. The CS also downloads event logs recorded in the WR3 HS.
3.3 ITE
A proprietary computer-software application, and its suite of applications, developed by ACS and provided as a service over the
internet for use by Service Providers, Service Centres, and others authorized by ACS for the delivery of Program Services –
including any upgrades thereto.
Depending on the jurisdiction, it may be necessary to download the event log once calibration is complete.
To learn more about ITE, refer to the ITE application manual.
3.4 Alcohol reference solution
The alcohol reference solution used in the CS is provided by ACS Corp in 500 mL containers. Each container is labelled with:
BAC value of the solution
Lot number of the solution
Serial (bottle) number of each container
Date of manufacture
Expiry date
Check that the solution is the correct value –50 mg/dL (0.50 g/L) –required for calibrating, and the date is not expired.
