Why is my Rae Measuring Instruments reading abnormally low?
If your Rae Measuring Instruments is reading abnormally low, it might be due to a dirty filter, in which case you should replace it. Another reason could be that the calibration adapter is attached; if so, remove it. Finally, the device might be incorrectly calibrated, so try calibrating the QRAE II.
What to do if my Rae QRAE II Measuring Instruments won't turn on after charging?
If your Rae Measuring Instruments won't turn on after charging, the battery may be discharged or defective. Try charging or replacing the battery.
What to do if the pump stalls too easily on Rae QRAE II?
If the pump stalls too easily or not at all on your QRAE II Pump, it could be due to incorrectly set stall values; in this case, adjust the stall values. Alternatively, the pump may be damaged, requiring you to replace the pump and recalibrate the monitor.
