Sonics VCX134 - Manual (Page 14)

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 01 second to 59 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 three seconds, a cautionary message - Sonics in OFF Cycle - will warn
the operator against touching the ultrasonic probe. To set the pulser, press PULSE
key.
