Level Meter - Phonic PAA3 User Manual

Level Meter

Measure the line voltage level in units of dBu, dBV,
and AC voltage, using standard response time,
and standard A, C, or flat weightings (under normal
conditions, flat is preferable). Using the PAA3 to
meaure DC voltage may damage the PAA3 and
will void the warranty.
Procedure:
Enter the SPL / LINE menu and set the
1.
measurement unit to dBu, dBV, or voltage,
as required.
You may select a range level, weighting,
2.
response time or a maximum level by going
into the SETTINGS menu, then onto the
appropriate menus. The selected values of
these options will be displayed above the
RTA on the PAA3's default screen.
On the main RTA display, hold the ENTER
3.
button for approximately 2 seconds to
activate the Level Meter screen. Press the
ENTER button once to exit.
NB.You can easily refresh the Max SPL value by
holding both the ← left and → right keys
simultaneously for at least one second.
ATTENTION:
If the level is lower than 127 mV when measuring
voltage, the PAA3 will show it in mV. If the level
is higher than 127mV, the data will be shown in
voltage For example, 120mV will read as 120.0mV,
and 200mV will be shown as 0.2V.
The measurements for line voltage cannot be
saved into the memory of the PAA3.

MEMORY
The sub-menus of MEMORY include: STORE,
RECALL, AVERAGE, EQ SETTING. Through
these options, users are able to store their RTA
measurements.
Store
The user can save up to 10 sets of measured
data (1 to 10), as well as 6 averaged sets (A to
F), into the memory of the PAA3, allowing them
to be used later for further analysis or uploading
to your computer.

indicated with a box surrounding the slot
number.
Selecting A/C in the STORE menu will
