1) What is the recommended method for cleaning a breath test instrument?
Use of a cloth dampened with soap and water is an acceptable method on exterior surfaces of the instrument. Special attention needs to be paid when cleaning the instrument so that moisture does not get onto the electronic circuit boards or into the internal sample path.
There are certain disinfectant products that can be used. This is discussed more thoroughly in the attached document under the "More Info" link.

10) Why is 0.01 often used for zero tolerance testing?
"With a breath test instrument, as long as the sampling was proceeded by a 15 minute deprivation period, results of 0.01 or above , on a properly calibrated instrument, indicates that alcohol is present. This is consistent with the reporting of blood samples. Blood samples are usually reported as a two digit result (.##) therefore , when using blood, 0.01 is the lowest reported result. "
