Int./Diff

: To show the mathematical

relationship between the SU (Sensor Unit)

and the DU (Display Unit), this could be

integration once, twice or differentiation

once or twice. This is reference only and

cannot be changed.

Weighting

: Select No, A or C. A and C

weighting is for acoustic measurement.

User Def. Unit

: The User Defined Unit

can be entered via the [

Navigation Keypad

]

by selecting the desired unit. There may

be a time where you need to display units in

a different format other than the ones listed.

Unit Definition Table:

In this table, we show what the scaling factors are for

each unit, the int./diff and the unit. In this table, the user can create their own

table, factors and units that they wish to use.
