IMPORTANT
To ensure repeatability and accuracy, always depress the TEST button after changing the OUTPUT
CONTROL setting.
NOTE
Whenever the pulser is used, the TIMER and ENERGY CONTROLLER will accumulate and register
the time that has elapsed and the energy that has been delivered to the sample ONLY during the ON
cycle. When working with a new application, or when time and energy settings are unknown, proceed
as follows:
a. Set TIMER to maximum (99 minutes / 59 seconds).
b. Set ENERGY CONTROLLER to maximum (99999).
c. Activate the unit by depressing the START switch. If the footswitch is used, depress the
footswitch.
d. When desired results are obtained, stop the ultrasonics and record the time displayed on the
TIMER, and the amount of energy displayed on the ENERGY CONTROLLER.
The ultrasonics will automatically de-activate when the duration set on the TIMER has elapsed, or
when the energy level set on the ENERGY CONTROLLER has been reached. The ultrasonics can
also be de-activated at any time by depressing the STOP button.
As the volume or viscosity increases, so does the need for higher power output. A sensing network
continuously monitors the output requirements, and automatically adjusts the power output in order
to satisfy the needs of the application. The actual power delivered will only be that required by the
application. The greater the resistant to the movement of the probe (resulting from higher viscosity or
larger volume) the greater the reading on the WATTMETER.
