Study Notes
Device Overview
- Monitors gases in ambient air and workplace environments.
- ALTAIR 5X PID equipped with a maximum of five sensors; can display readings for up to six gases.
- Two-Tox Sensor allows detection of CO and H2S or CO and NO2 in one unit.
- Device features a color display and factory-set alarm levels adjustable via Instrument Setup Menu or MSA Link Software.
Gas Monitoring Capabilities
-
Combustible Gases:
- Catalytic sensor detects gases up to 100% LEL (Lower Explosive Limit); displays as % LEL or % CH4.
- Two alarm setpoints: HIGH and LOW; alert user to dangerous concentrations.
- Lock Alarm state engages when readings exceed 100% LEL; device shows "XXX" instead of actual reading.
-
VOC Gases:
- PID sensor detects various VOC gases; readings displayed in ppm, µmol/mol, or mg/m³.
- Can detect up to 30% oxygen but approved for use up to 21%.
Device Hardware Interfaces
- Operation facilitated through three function buttons:
- q Button: Power On/Off and confirms selections.
- Button: Pages down, decreases values, starts Bump Test. Accessible features depend on user permissions.
- Button: Resets values, performs calibration, pages up, or increases settings.
LED Indicators
- Red Alarm LEDs: Visual alerts for alarm conditions or device errors.
- ♥ indicator signals sensor nearing end-of-life.
Safety Features
- Sampling system undergoes a safety test at startup; failure to block flow triggers an error message.
- Pump alarm must activate when sampling line is blocked; absence of alarm may result in inaccurate readings and potential hazards.
Fresh Air Setup (FAS)
- Automatic zero adjustment initiated at device turn-on.
- FAS cannot be performed if a hazardous gas is present; device alarm activates in such cases.
- Inaccurate readings can result from unclean air during FAS; daily calibration checks are essential.
Oxygen Sensor Considerations
- Oxygen sensor readings may be suppressed for up to 30 minutes during 'cook down' after installation or battery issues.
- Displays "PLEASE WAIT" during this period; prevents Fresh Air Setup, Calibration, or Bump Test until oxygen reading stabilizes.
Measurement Mode Features
- Measurement screen provides access to:
- BUMP Page: Undertakes Bump Test for sensors.
- Peak Page: Shows peak readings for all sensors.
- Min Page: Displays minimum oxygen sensor readings.
- STEL Page: Shows calculated Short Term Exposure Limit readings.
- TWA Page: Shows calculated Time Weighted Average readings.
- Date Page: Displays current date settings on the device.
