  • Page 31 STEL • Short Term Exposure Limit (STEL) – The STEL is the average reading of the gas concentration for the last 15 minutes. – NOTE: The STEL reading does not appear until 15 minutes have elapsed.
  • Page 32 • Time Weighted Average (TWA) – The TWA is the accumulated reading of the gas concentration, divided by 8 hours, since the monitor was turned on.
  • Page 33: Data Logging

    Datalogging • Automatic – 1 minute intervals – 5 days continuous data storage – Wrap-around memory • Stops when the monitor is in Programming Mode – Resumes when the monitor is back in Monitor Mode • Use ProRAE Studio software to manage datalogged data...

  • Page 48 Calibration • Multi-Sensor Calibration – When “Span Cal?” appears on the display, press Y and turn the gas all the way – The monitor will countdown from 70 seconds.
  • Page 49 Calibration • Multi-Sensor Calibration – When the countdown is done, compare the readings displayed on the monitor to the span gas values indicated on the gas cylinder – The readings should closely agree with the span gas values.
