PULSER: 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 59 seconds. During the OFF portion of the cycle, the red indicator on the PULSER
key will illuminate. If the OFF portion of the cycle exceeds three seconds, a cautionary
message – CAUTION – PROBE ON STANDBY – will warn the operator against
touching the ultrasonic probe. To set the pulser, press the PULSER key.
