RANGE

The RANGE selector lets you select one of

seven sound level ranges, each spanning

16 dB. The

RANGE numbers refer to the

center points of the seven ranges. The

needle level indicator shows the actual

sound level as a displacement from the

center point. For example, if

RANGE is set

to

80 and the meter scale reads –3, the

actual sound level is 77 dB (80–3). If the

meter scale reads

0 (same as the value

where

RANGE is set), the actual sound

level is 80 dB (80+0).
