5.1 Noise criteria number Calculation
Criterion for the noise is calculated. Calculation of the noise criterion can be performed for
the measurement data with the same data format as follows.
● Noise measurement data (Automatic measurement data) of either of L
A
/ L
C
/ L
P
for which
the measurement interval is set to 「Repeat」.
Calculation procedure is as follows.
1. Select measurement data files subject for the calculation from the measurement data file list
and select the Logging panel.
2. To specify desired time range for the calculation, left-click the mouse at the desired start
point of the time and then move the mouse while keeping the left-click to the finish point of
the time and release the left-click.
