PULSE: By inhibiting heat build- up in the sample, the pulse function enables safe
treatment of temperature sensitive samples at high intensity. In addition, pulsing
enhances processing by allowing the material to settle back under the probe after each
burst. The ON and OFF pulse duration can be set independently from .1 second to 9.9
seconds. During the OFF portion of the cycle, the red indicator on the
PULSE key will
illuminate. If the OFF portion of the cycle exceeds two seconds, a cautionary message -
CAUTION – PROBE ON STANDBY – will warn the operator against touching the
ultrasonic probe. To set the pulser, press PULSE key.
