Figure 16 — Setting of OMI
totrms
The display in % (absolute) and dB (relative) enable an easy comparison with calculation results as de-
scribed earlier.
Notes:
1) OMI nominal refers to a factory setting and cannot be changed by the user.
2) OMI
totrms
setting is only relevant in AGC-On mode.
3) The setting range for OMI
totrms
might change slightly from device to device due to production tolerances.
