Sonics VCX1500HV - Manual (Page 13)

PULSER:* The pulse function is not used when working with the High Volume Flow
Cell, but can be used when processing a batch with a probe. 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.
