SPECIFICATIONS:

FUNCTIONAL

• Power Switch: Activates breath tester.

• Start Test Switch: Brings the unit out of standby and activates the test mode sequence.

• Software Mode Selection: Features such as data entry, printing, test mode, digits displayed, etc. can be changed by accessing the features setup menu using the keyboard.

• Digital Display: A 14-segment, 16-character, dot matrix (vacuum fluorescent) alphanumeric display which signals the operation of the unit, alerts the operator to required actions, and gives the alcohol test concentration in weight per volume.

• Audible Tones: Signal the completion of an operation, the presence of a malfunction, an incorrect operational procedure, or an unfulfilled test requirement.

• Printed Test Record: Provides a printed record of the date, model and serial number of the instrument, the test results and time of the test on a multi-copy card or single/double ply roll paper.

• Breath Sampling: Instrument automatically senses end expiratory air (alveolar) using the technique of slope detection in conjunction with a minimum volume and minimum time requirement.

• Keyboard: Keyboard is used to set time and date, set software mode switches, initiate maintenance and diagnostic routines, and input test data in the test record.

• Calibration: The instrument is factory-calibrated and does not require periodic calibration adjustments as do fuel cell-equipped instruments.

• Communications: The instrument is equipped with an RS-232 port for external computer interface.

• Recirculation: The instrument is equipped with two solenoids, which re-circulates simulator vapor and extends the life of the simulator solution.

• Standby Mode: Standby mode reduces dust accumulation in the instrument and increases component life by shutting down non-vital functions during inactive periods.

• Remote Turn-On: Allows the operator, via a phone modem, to change the instrument from standby mode to testing mode for remote diagnostics, control checks or record transfer.

• Breath Volume Measurement: A flow sensor allows breath volume information to be calculated and printed during each test.

• Gas Calibration Ready: The instrument is equipped to use dry gas calibration verification medium as well as wet bath simulation.

• Barometric Pressure Measurement: If dry gas is used as a calibration verification medium, a barometric sensor is included to provide automatic correction for barometric pressure.
