3.b)  Passive mode: For this mode you don’t need a 

mouthpiece. As soon as you can see “0” on the 

display, hold the mouthpiece connection on top 

of the device in front of your mouth and press the 

power button while you exhale. You see 4 times a 

“0” blinking on the display and then the result: If 

you see “P” (= Pass) then the test result is below 

0.02% BAC and if you see “F” (= Fail) then the test 

result is higher than 0.02% BAC. For DUI the legal 

limit in the USA is 0.08% BAC (status: Oct 2016).

 
*  

If you press the power button constantly for 2 seconds, you can 

see the letter “C” and “A” - each followed by a number. Please 

read the display indications for the explanation of the meaning!

IMPORTANT NOTICE: WHEN YOU HAVE EATEN,  

DRUNKEN ALCOHOL OR SMOKED A CIGARETTE,

WAIT AT LEAST 15 MINUTES BEFORE STARTING THE 

MEASUREMENT. ANY TEST CONDUCTED PRIOR TO 

THE EXPIRATION OF THE RECOMMENDED WAITING 

PERIOD WILL RESULT IN INACCURATE RESULTS. 

IF THE TEST RESULT IS BELOW 0.005 % BAC THEN 

THE DEVICE SHOWS 0.000% BAC ON THE DISPLAY. 

THIS HAPPENS BECAUSE AT A LOW RANGE OF 

ALCOHOL CONCENTRATION IT IS POSSIBLE TO 

MEASURE OTHER MATERIALS IN YOUR MOUTH.

ACE INSTRUMENTS ADVISES:

 

 

EVEN IF YOU GET A RESULT MEANING „SAFE RANGE“, 

YOU SHOULD NEVER DRIVE AFTER CONSUMING 

ALCOHOL OR DO ANY OTHER ACTIVITIES THAT ARE 

SEVERELY IMPAIRED BY ALCOHOL CONSUMPTION 

AND MIGHT ENDANGER YOUR HEALTH AND SAFETY 

OR THE HEALTH AND SAFETY OF OTHERS.

ACE INSTRUMENTS RECOMMENDS: 

  ALWAYS USE A NEW MOUTHPIECE FOR EACH PER-

SON AND TEST THAT IS CONDUCTED. ACE INSTRU-

MENTS ASSUMES NO LIABILITY FOR ANY DAMAGES 

WHICH ARISE WHEN SEVERAL PEOPLE USE THE 

SAME MOUTHPIECE FOR MULTIPLE TESTS.

  ONLY USE THE PROVIDED SINGLE PACKED AND  

HYGIENIC MOUTHPIECES – MORE ARE AVAILABLE 

AT WWW.ACE-INSTRUMENTS.NET. DURING EACH 

TEST THE BREATHALYZER´S INTERNAL AND EXTER-

NAL PARTS COME INTO CONTACT WITH HUMAN 

SECRETION (SALIVA, BLOOD, SWEAT, ETC.)!

  USE SAFTEY GLOVES WHEN PULLING OUT A 

MOUTHPIECE USED BY ANOTHER PERSON!  

YOU CAN BUY APPROPRIATE GLOVES E.G. AT  

ACE TECHNIK (WWW.ACE-TECHNIK.DE).

Conducting the measurement:

1.    Press the power button to turn on the device

 * 

 

(the device beeps once).

2.    The device warms up until you can see ”0” on the 

display (additionally the device beeps twice).

3.a)  Active mode: As soon as you can see “0” on the 

display blow through the mouthpiece into the 

unit for 4 seconds (you can hear a beep tone 

during the test) until the sound (a “tic-tac” tone) 

concludes.

Preparation for the test:

1.  Open the battery compartment cover at the back of 

the device: First push the cover up and then sideways. 

Then you have to remove the small paper inside the 

battery compartment which prevents the battery 

discharge. If you exchange old batteries against new 

ones please mind the battery polarity (+/- pole).

2.  For the active mode operation put a mouthpiece on 

the mouthpiece connection, which is on top of the 

device. Make sure it is attached properly. Use a differ-

ent mouthpiece for each test person. Avoid blowing 

cigarette smoke into the tester! The passive mode is 

described in chapter “Conducting the measurement”.
