SECTION 4. SONIC RUPTOR 400 OPERATION
4.4 TIMER SETTINGS
The Timer is adjustable from 1 to 15 minutes. The timer is turned off when the knob is in the
fully counter-clockwise position.
When the Timer control knob is set to a desired number of minutes, the Timer LED will light
to indicate that the Timer is on.
4.5 PULSER SETTINGS
The Pulser knob allows for two different power output modes:
Constant mode
Pulse mode
The pulse mode applies ultrasonic energy to the tip at a rate of one pulse per second. The
pulse duration can be adjusted from 10% to 90%, enabling a solution to be processed at full
power range while limiting temperature. The pulse mode is especially valuable for processing
heat sensitive samples.
Example:
Time = 5 minutes
Pulse = 10%
The unit will pulse every 0.5 seconds for 5 minutes.
The constant mode is operative when the knob is in the fully counter clockwise position.
4.6 START & RESET
Start Button: Pressing “Start” begins the ultrasonic processing at the preset power lever, puls-
er, and time.
Reset Button: Pressing “Reset” interrupts the processing. When the instrument is turned on
but is not engaged in processing, it is in the idle state.
