Branson S83 - Power Modulation Mode (S85 Only)

S83/85 Ultrasonic Generator Operation

4.5 Power Modulation Mode (S85 only)
Power modulation creates power bursts at a 4 : 1 ratio between peak power and the average power.
When not in power modulation, the ratio between the peak and average power is 2:1. This feature
is helpful when working with liquids that are normally difficult to cavitate such as semi-aqueous
solutions. Activate power modulation by pressing the PWR MOD button on the front panel.
• The generator must be off to enter the power modulation mode.
• Sweep will be inactive in the power modulation mode.
• Power modulation can be set from the panel when operating in the remote mode.
