Q = 3, 4, 5, and 6. The key may also be used when both

and keys have been used to change criterion or threshold

levels in the current calculations.

However, if time history profiles are being displayed, as the one

minute L

value calculated with Q = 3 is the subject of a

separate profile (1 min. L

), when L is displayed, pressing

the key cycles through results calculated only with Q = 4,

5, and 6.

3.3.11 Criterion Key

(yellow key: enables results to be calculated with different

criterion levels)

This key is active only while %Dose, Projected %Dose or L

values are being displayed.

Pressing this key shows the current criterion level on the main

display, while pressing the key again selects the next valid level

from a series of up to six criterion levels for use in the calcula-

tion.

Then pressing the relevant working area key again returns the

display to whichever parameter was being inspected, so that re-

sults calculated with the new criterion level can be seen.

Refer to Table 1 in Section 2.2 for details of valid criterion levels.

These may include 70 dB, 75 dB, 80 dB, 84 dB, 85 dB and

90 dB.
