5.5.6 Reference Value Setup
In the test menu, press REF/SEL key for more than 2 seconds, then the LCD will display REF in red (see Fig. 5).
This will set the current measurements as the Reference values. The test results after setting the reference are
relative to the reference value which is useful to measure deltas. The units will be displayed in dB and the LED
indicators will not light.
In the test menu, press and release REF/SEL key quickly (less than 2 seconds) to briefly show the reference values in
dB/m that are currently stored. See Fig. 6.
