TIMER key
Used with the numeric keys to set the duration of ultrasonic application –
from 1 second to 9 hours, 59 minutes, 59 seconds.
TEMP key
Used with the numeric keys to set the high temperature limit – from 1?C to
99?C. Red indicator lights when the temperature limit has been reached.
PULSE key
Used with the numeric keys to set the pulse mode. The ON cycle and OFF
cycle can be set independently from .1 second to 9.9 seconds. Red
indicator lights when pulser is in the OFF portion of the cycle.

off.
ON/OFF power switch

TUNER
(located below the control panel)
Optimizes performance by matching the frequency of the power supply to
that of the converter / probe assembly
AMPLITUDE control
(located below the control panel)
Controls the amplitude of vibration at the probe tip.
CAUTION
When using a microtip, never allow the amplitude to exceed 40%
