4.6 Sweep Mode Function
4.6.1 S83 Sweep Mode
Sweep is always on at a fixed rate of 80 Hz and a bandwidth of +/- 700Hz.
4.6.2 S85 Sweep Mode
Sweep Mode allows the ultrasonic power supply to operate above and below the operating
frequency. In Sweep mode, the operating frequency constantly changes, sweeping from 1000 Hz
below to 1000 Hz above the operating frequency. This helps cleaning activity in the tank. The
following figure shows the bandwidth:

Two other functions are used to set Sweep: the Rate function and the Sweep Width Adjustment
port.
Notes: Sweep mode becomes inactive at the front panel when operating the ultrasonic power supply
in Remote mode or Power modulation mode.
Before pressing the SWEEP button, make sure that:
o You have the adjustment tool (supplied with the ultrasonic power supply) or 1/8” flat-
blade screwdriver for adjusting the Sweep adjustment potentiometer; and
o The ultrasonic power supply is powered up.
