LOW - Indication
The low indicator for an individual level < is displayed when:
The measured sound pressure level is below the selected •
linear measurement range. In this case the results shown
are most likely higher than the actual sound pressure level ->
choose the next lower measurement range.
The measured sound pressure level is just above the resid-
•
ual noise of the connected NTi Audio measurement micro-
phone, which reduces the measurement accuracy -> choose
another microphone dedicated for low level measurements.
