Displayed Parameters
The Measurement Window displays two parameters on the
bottom two lines of the screen, though eight parameters are
monitored by the instrument at all times. Press
to step
through the readings. You are able to change the displayed
parameters both during and after measurement. The flowchart
below details the available paired choices. Note that the fre-
quency weighting (H) shown in the screens in Fig. 7.2 may
differ from your own, depending on your settings. For more
information, see section 3.4.
