indicate that it is a reference value. The displayed value only lasts 1
second.
2. Press and hold the “REF” key over 2 seconds to store the presently
measured value as the new reference value for the
current wavelength. During the process the “REF” sign
flashes twice on the screen and buzzer sound is heard.
Once the new reference level is set, the AQ2170
switches to the dB measurement mode. The displayed
value only lasts 1 second.

for over 2 seconds, the unit will be shifted to
"dB" automatically.
