      Danielle HayesAug 20, 2025
      If the MSA Monitor display flashes Err 1*, it indicates that the sensor cell is detected as missing or the sensor body is damaged. Inspect the cell for proper placement. If that doesn't solve the issue, or if the sensor body is damaged, replace the sensor body and perform an Initial Calibration. After recovery, check if the display shows CAL.

    What does it mean when my MSA Monitor display shows UND?
    • T
      Thomas LeeAug 22, 2025
      If the MSA Monitor display shows 'UND', it means the cell signal is under-range. Try performing a regular zero or full calibration. If calibration fails, check if the display shows 'CAL FAULT'. If 'UND' persists after these steps, replace the cell and perform an Initial Calibration.

    What causes the MSA Monitor to display LO FLO?
    • A
      Angie ClarkeAug 27, 2025
      If your MSA Monitor shows 'LO FLO' on the display, it means there's restricted air flow or the pump is inoperative. Try clearing the tubing to remove any obstructions. If the issue persists, the pump may need to be replaced.

    Why is my MSA Monitor giving a low gas reading?
    • R
      Rebecca BlakeAug 30, 2025
      If the MSA Monitor gives a low gas reading, it could be due to a clogged sensor water stop disc, a misaligned stop disc, or poor gas flow/damaged cell. Try cleaning or replacing the disc. If that doesn't work, realign the disc and gasket. For poor gas flow or a damaged cell, check if the display shows 'CAL FAULT'.

    What does error Err 4 mean on my MSA Toxgard II?
    • R
      Robert ChavezSep 9, 2025
      If the MSA Monitor display shows Err 4, it indicates that the non-volatile memory has been reset or not initialized, or that the cell type has changed. Perform an Initial Calibration to resolve this. It could also be caused by a damaged sensor or sensor body, in which case you should replace the sensor or sensor body and perform an initial calibration.
