Mode

Pressing the Setup button on the Home screen brings you to the Setup screen:

Here you can globally adjust the output voltage for the P15. Bear in mind that the P15 will output the

same voltage from all zones. They are not individually adjustable.

Variable MultiWave Strength adjustment is available here. This feature can be enabled by pressing

the MultiWave button on the Home screen. Variable MultiWave empowers users to vary the strength

of the MultiWave output according to the needs of the equipment and the resulting performance

benets. To toggle this feature on and o simply press the Waveform Button in the Main screen.

Phase tuning is the next adjustment. Increasing or decreasing this will move the point at which the

P15 detects the incoming waveform as the wave crosses the 0 Voltage point. In places where the

AC power is especially poor making small adjustments to this setting can potentially lower the THD

output. The best recommendation would be to keep this at zero unless you are seeing THD output

higher than 1-2%.

Pressing the ‘auto-tune’ button will calibrate the phase setting to the optimum setting for your input

power. This only needs to be performed whenever the unit is moved to a new area to maintain

optimal performance.

The Mode setting gives you the choice of High Regulation or Low Distortion. High Regulation is

the default mode and ensures that the P15 will output the voltage very precisely at the expense of

potentially higher distortion (THD). Low Distortion mode ensures that the P15 will output the lowest

possible distortion at the expense of more uctuations in the output voltage. Choose the option that

best suits your needs.

Dimmer

The Dimmer slider allow you to manually adjust the brightness of the screen. Simply move the slider

left or right to choose the brightness setting that is suitable for you.
