FUNCTIONS OF KEYS, CONTROLS, INDICATORS, AND CONNECTORS
POWER SWITCH Applies power to the instrument. Illuminates when power is on.
START BUTTON When depressed, activates the ultrasonics. Also resets the TIMER and
ENERGY CONTROLLER to zero.
STOP BUTTON When depressed, de-activates the ultrasonics.
TEST BUTTON When depressed, allows the power supply to be tuned. When released,
automatically subtracts power consumed by the transducer and horn to
ensure that the power displayed on the wattmeter is the net ultrasonic
power delivered to the sample.
TUNE CONTROL Optimizes power supply performance by tuning the power supply to the
converter/probe assembly. To adjust, use only a non-magnetic, flat-
blade screwdriver.
TIMER ON/OFF
Enables/disables the timer function.
TIMER
Sets the duration of ultrasonic application in minutes and seconds.
PULSER Sets the duty cycle. In the OFF position, the ultrasonic is continuous. In
the ON position the ultrasonics intermittent. The ON cycle and OFF
cycle are independent of each other and can be adjusted from .1 second
to 5 seconds. Intermittent operation inhibits heat build-up in the liquid
and provides more efficient processing by allowing the material to
settle back under the probe tip after each burst.
WATTMETER
Indicates the net amount of watts being delivered to the liquid.
ENERGY CONTROLLER Controls and monitors the net amount of energy (joules) (watts -sec)
delivered to the liquid. In the ON position the energy controller is
energized. In the OFF position, the energy controller is de-energized.
OUTPUT CONTROL Controls the amplitude of vibrations at the probe tip.
CAUTION: when using a 2mm (5/64”) probe, never exceed “60” on
output control
