3. Scale window
When measurement mode is selected (except the two-frequency), Scale working window
appears first fig.А.3.
Fig. А.3
Visual indication button can lead to the indication modes
of Graph (fig.А.4) and Acoustic
signal spectrum(fig.А.5) or Power range spectrum (fig.А.6) and Broadband electromagnetic
range (fig.А.7).
Sensitivity
- sensitivity symbol
«_dB»
-the value of input
amplification factor(0…62dB

)
- ensitivity scale
Two-segment scale
reflects the processed signal
Light segment:
- in the mode
-current
value of the signal (valid +
interference):
- in the mode
- current
value of the signal for the previous
second (pulse amplitude).
Dark segment:
-in the mode
- level of the
processed valid signal;
- in the modes
and
-current signal
level(valid+ interference)
A completely filled scale
signifies output overload
Filtering
Displays the frequency range
scales with numerical and graphical
representation of the pass band
During work with AD:
- pass band filter
- broadband
During work with EMD:
- central frequency of the
narrow band filter
- broadband
Presence of the indicator
signifies
possibility of filter parameter
adjustment.. The filter is switched on
and off by using the filter button
