The instrument is powered by three AA alkaline batteries and is designed to operate for 2000 hours in Non-alarm State.
Oxygen analysis is linear across the single range of 0-100% using Teledyne’s class R17MED oxygen sensor. A unique sensor failure alarm is incorporated which warns the user if the sensor signal is lost or low. When this occurs, the √ SENSOR display flashes. The alarm buzzer can be silenced by pressing the ALARM SILENCE key () or pressing the unlock key.
