Step 3: Adjusting the Sensitivity Level
There are nine sensitivity levels displayed on the LCD. When the
power is first connected, the default sensitivity level is 1. You can
change the sensitivity level from 1 to 9 with the “Sensitivity
▲
” and
“Sensitivity
▼
” buttons. Setting the sensitivity to a higher number
increases the amount of AC-line noise that will be detected.
Step 4: Saving the AC-Line-Noise Level
You can compare the AC-line noise between different AC-line sources.
Press the “Memory” button once to save the present level of the
AC-line noise. The line-noise level will be saved and will display on the
LCD as the “reference” noise level. Then, plug the power cable into
a different AC-power source and you can compare the AC-line noise
between both sources.
Step 5: Turning the Loudspeaker On/Off
Press the “Sound” button once to turn the loudspeaker “on”. You
will see the “Sound” indicator (green LED) illuminate. This provides
an audible representation of the AC-line noise. You can turn the
loudspeaker “off” by pressing the “Sound” button again.
Note:
You can press the “Memory” button to remember your last
setting for the loudspeaker. You can have the loudspeaker default
to either an “on” or “off” by pressing the “Memory” button before
unplugging the unit.
