Accumulation: AC 01
Users are able to accumulate various RT60 calculations
by pressing enter while the “ACxx” (where xx equals the
number of accumulated values) option is highlighted. Up
to 30 measurements can be accumulated. When RT60
measurements are accumulated, the average of said
memories is automatically taken and displayed onscreen.
After 30 memories have been accumulated, users will be
forced to store their data, or else lose it.
Store: STO
Storing the results of RT60 measurements is simple. First
highlight the STO option and push ENTER. When the store
page comes up, choose one of the memory slots from 1 to
10, and select YES to store. The memory slot you selected
will have a box surrounding the number now, as to indicate
that a memory is stored in that particular slot. Selecting
“A/C” will clear all memory slots.
Recall: RCL
RT60 measurements can be recalled at anytime by
selecting the “RCL” option in the RT60 menu. Memory
slots 1 to 10 and A to F can all be recalled with ease. Each
memory location page displays only 4 memories at a time,
however, therefore users must select NEXT to continue
onto the next page of stored memories.
Average: AVG
To get the average of RT60 measurements that are stored
in the PAA3, simply select AVG. Select from memories 1 to
10 (memory slots with saved data are indicated by a box
surrounding the slot number), a dot will appear next to the
number to show that a memory slot is selected. When all
memories are selected, simply select AVG to determine
the average, or ESC to escape. When differently weighted
items are attempted to be averaged, a warning will appear
onscreen advising users to select again.

of any or all frequencies. If all frequency readouts are
needed, press “ENTER” button (or the jog control) for
two seconds to enter line level meter.
