Introduction
Thank you for purchasing our ACE A breathalyzer! It measures
the alcohol concentration in human breath using an electroche-
mical sensor and calculates the blood alcohol content.
The test results are very reliable and have a tolerance of
+/- 0.075‰ (per mill) with reference to 1.00‰ at 25°C ambi-
ent temperature. The measurement results are displayed as a
3-digit number with 2 decimals and are interpretable 1: 1 (for
example the display shows the value 0.36 = 0.36 per mill).
With the measurement unit % BAC the test result is displayed with
4 digits and 3 decimals.
The fuel cell sensor inside the Breathalyzer can be calibrated.
To maintain the measurement accuracy of this device and the
sensor warranty, it should be calibrated regularly. For a calibra-
tion service, you can send the device to the service address
specified at www.alkomat.net.
The device must only be used pursuant to the instructions men-
tioned in this manual. All measured values determined by this
breathalyzer are only a guide and not legally binding. Breath
tests should be carried out using clip-on mouthpieces (one new
mouthpiece should be used per test for reasons of hygiene and
to avoid falsified readings).
