Horizontal Time Option (HOR): Featured on the Scope function, the horizontal division option allows
users to adjust the value of time between each horizontal segment (or 'division') of the scope's display
grid. The horizontal division time can be adjusted between 0.17ms, 0.33ms, 0.5ms, 1.0ms, 2.0ms,
5.0ms, 8.0ms, 10.0ms, 20.0ms, 50.0ms, 80.0ms, 100ms, 200ms and 500ms. There are a total of 10
horizontal divisions displayed.
Polarity
The polarity function is most useful in determining whether a speaker is correctly wired. A polarity
signal is typically required when checking the phase of a speaker. Thankfully, one is provided through
the onboard signal generator.
Procedure for checking the polarity of speakers:
1. Go to the Polarity function.
2. Go to the SET menu (figure 56) and select MIC as your input source. Exit the setting menu.
3. Connect the signal generator output to your sound system's inputs. Ideally, with active speakers,
you will connect the signal generator into your speakers to avoid the complication of finding miss-
wired cables elsewhere in your setup.
4. Start the polarity tone playing by pushing the signal generator on/off icon. You could also opt to play
a polarity signal through your speakers through some other means (compact disc, external tone
generator, etc.).
5. Stand approximately one meter (3 or 4 feet) in front of the speaker that plays the polarity signal.
6. Activate the polarity function by pushing the PAA6's Run/Stop button (either on screen or on the left
hand side of the unit).
