Error in measuring
value Variable Calibration value incorrect 1. Check FSO in atmospheric air. Hold the transmitter up
in the air with the sensor downwards. Check the value
against DS/EN 25814 (see appendix IIa)
2. Check zero point (see appendix IIb)
3. In the case of large reading error, recalibrate
