  • Page 10: Charging The Qrae Ii Battery

    Always fully charge the battery before using the QRAE II. The QRAE II’s Li-ion battery is charged by placing the QRAE II in its cradle. Contacts on the bottom of the QRAE II meet the cradle’s contacts, transferring power without other connections.
  • Page 11: Low Voltage Warning

    When the battery’s charge falls below the shutoff voltage, the display shows: Battery low, turning off. . . The QRAE II then turns itself off. Recharge the battery by placing the QRAE II in its cradle. Clock Battery An internal clock battery is mounted on one of the QRAE II’s printed circuit boards. This long-life battery keeps settings in memory from being lost whenever the Li-ion battery or alkaline batteries are removed.
  • Page 12: User Interface

    QRAE II User Guide 3 User Interface The QRAE II’s user interface consists of the display, LEDs, an alarm transducer, and two keys, labeled [MODE] and [Y/+]. The LCD display provides visual feedback that includes time, sensor mode, battery condition, and datalog enable/disable status.
  • Page 13: Turning The Qrae Ii On

    The QRAE II checks the oxygen sensor to determine whether it needs conditioning. If the sensor is new or has been in a QRAE II with its battery removed for a long period, it requires conditioning. If conditioning is required, it can take anywhere from 150 seconds to several minutes.
  • Page 14 1. Wait. This means that the monitor will run a second cycle of conditioning. 2. Measure. This means that the QRAE II will exit the conditioning menu and continue the start-up process. Note: The time necessary for conditioning depends on how long the monitor has been without power.
