5. If the function control parameters have been previously stored for a particular

application, use the RECALL key to retrieve the control settings for that

application.

6. To energize the ultrasonics, press the START key or the optional footswitch. To

de-energize the ultrasonics, press the STOP key or release the footswitch.

7. Following 10 minutes of continuous operation, check the sample temperature. If

the temperature has increased, retune the power supply in accordance with the

procedure outlined.

8. The REVIEW function provides a “window” on the process by displaying various

operating parameters without process interruption. Pressing the ENTER/REVIEW

key repeatedly during processing will consecutively display the following

information.

a) Selected amplitude:

e.g. Amplitude Control 10%

b) Set and read temperature:

e.g. Temp Set 35?C Probe 27?C

c) Set processing time and elapsed processing time:

e.g. Set 5:30:25 Time 0:57:03

d) Selected pulsing cycle, and actual pulsing cycle:

e.g. Pulse 2.2 2.2/1.7 2.2

e) Amount of power in watts delivered to the probe:

e.g. 123 watts

f) Elapsed time since processing was initiated:

e.g. Elapsed time 1:27:33

NOTE

If the START key is pressed and the time limit has not been set, processing will remain

uninterrupted until the STOP key is depressed.

If the START key is pressed and the time limit has been set, processing will remain uninterrupted

until the set time limit expires, or the STOP key is pressed – whichever occurs first.

If a footswitch is use, and the time limit has not been set, processing will remain uninterrupted as

long as the footswitch is depressed.

If a footswitch is used, and the time limit has been set processing will remain uninterrupted until

the time limit expires or the footswitch is released – whichever occurs first.

The START key and footswitch are mutually exclusive. If the process is initiated by the START

key, the footswitch becomes inoperative. If the process is initiated by the footswitch, the STOP

key becomes inoperative.

NOTE

If the processing time has been set, processing can be suspended for tuning purposes by pressing

the HOLD key before and after tuning the power supply. In the hold mode, the red indicator on the

HOLD key will illuminate, signaling that the processing cycle has been interrupted.
