  • Page 43: Alarms

    ALARMS 3.1 GAS ALARMS Gas alarms are enabled when the instrument is switched Note: Alarms are disabled during warm-up. All gas ranges have alarm limits that trigger the alarm if the measured gas value exceeds the set level. If a preset alarm level is exceeded, the audible alarm sounds, the LED’s flash RED and the gas range in alarm flashes on the display.

  • Page 44: Oxygen (O2) Alarm Limits

    V!SA - USER HANDBOOK 3.1.3 Oxygen (O ) Alarm Limits Up to one (1) upper and two (2) lower alarm limits are programmable, each with different pitch and tone. All alarms are user configurable to meet the specific needs of different companies.
  • Page 45 ALARMS changed, if required, via the instrument set up software, or as detailed in the ‘CONFIGURATION HANDBOOK’. In the following two examples, Fig. 3.1 shows a four-gas instrument signalling a ‘Lo Lo’ Oxygen alarm and Fig. 3.2 shows a four-gas instrument signalling a ‘Hi Hi’ LEL alarm. If more than one gas alarm level is exceeded, the gas value will flash for each gas type in alarm.
  • Page 46 V!SA - USER HANDBOOK Fig. 3.2 ‘HiHi’ Alarm Each alarm can be latching or non-latching. Latching alarms must be cleared by the user when the gas level returns to within the preset alarm limits. Non-latching alarms clear automatically when the gas level returns to within the preset alarm limits.

  • Page 47: Acknowledge Gas Alarms

    ALARMS 3.2 ACKNOWLEDGE GAS ALARMS Caution: Never remove the battery to silence / mute an alarm as this can damage the instrument.
