Summary of Contents for Santacary XAR-O

  • Page 1 User Manual R1.2 Santacary Technology Co., Ltd. XAR-O O Gas Detector...
  • Page 2 INTRODUCTION Santacary XAR-O is a precise gas detector for monitoring Oxygen (O ) in the ambient air and in the work place. It has been designed to protect the safety of workers in dangerous work places. The XAR-O will continuously display the ambient concentration of oxygen and activate its audible alarms whenever the preset set points are exceeded.

  • Page 3: Theory Of Operation

     Four AA Alkaline Batteries THEORY OF OPERATION Santacary XAR-O O Gas Detector uses two-electrode electrochemical technology, operating by the diffusion principle, for determining the concentration of oxygen in air samples. In diffusion mode, the atmosphere reaches the air sampling ports on beside and top of the detector.

  • Page 4: Operation

    OPERATION 1. Power Button 1.1 Turn On/Turn Off Detector 1) When the detector is turned off, press Power button to turn on the unit. 2) When the detector is turned on, press Power button for 2 seconds to turn off the unit.
  • Page 5 When the unit is first turned on, it performs 60 seconds countdown for detector initial warm up, then enters normal display with current O concentration (% vol.), temperature (°C or °F), and humidity (%RH) readings displayed. If the detector is not used for a long time, the warm up time of oxygen sensor needs more than 5 minutes.
  • Page 6 5. Air Temperature 6. % Relative Humidity 2.2 Trend Chart Display XAR-O has a data log function that provides up to 2 hours history of O concentration. The trend chart displays the past readings for O . The time per division (indicates the chart's time per unit division) is 10 min / div.
  • Page 7 2. Time scale (farther to the right, longer time in the past) 3. Measurement name (O 4. Maximum value on the chart of O concentration 5. Minimum value on the chart of O concentration At the bottom of the chart, there are two numerical indicators: Max and Min.
  • Page 8 2.4 Ambient Air Calibration (20.9%) for O This detector can implement ambient air calibration (20.9%) when needed (such as annually). By pressing the Function button for 3 seconds, the detector enters into Calibration Menu. In this Menu, there are two items by pressing the Function button shortly to loop switching: “Fresh Air Calibration 20.9% O2”and “Exit”...
  • Page 9  When LCD backlight is off, press any button to turn on the backlight. ALARM Low Alarm and High Alarm XAR-O has two alarm set points: Warning (O : 23.5%, high alarm) and Danger (O : 19.5%, low alarm). The danger alarm is sounded for oxygen deficiency and the warning alarm is sounded for oxygen enrichment.

  • Page 10: Materials Supplied

    XAR-O is equipped with audio alarms to alert you when the ambient gas concentration exceeds one of the two alarm set points. When oxygen value is less than the defined low alarm set point (Danger alarm at 19.5%), the audio alarm will sound at 3 beeps/sec. When oxygen value exceeds the defined high alarm set point (Warning alarm at 23.5%), the audio alarm will sound at 2 beeps/sec.
