5.4 Switching measurement mode

There are three measurement modes you can choose by pressing the "dBm/mW" key
repeatedly, dB, dBm, watt. And when the result is displayed in watt, there are two options,
w and mw. The instrument will decide which one to use automatically according to the
numerical value itself.

5.5 Setting reference level

1. Press the "REF" key to display the stored reference level for the current wavelength and
a sign of "REF" will be displayed on the screen to 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 level 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 AD switches to the dB measurement mode. The displayed value only lasts 1
second.
