COUPLING FORCE MEASUREMENT (Model 1098 only)
To measure the actual horn coupling force, turn the head down key switch
clockwise. Then, as the head is descending, press the F TRIGGER key and
keep it depressed until the horn contacts the parts.
The coupling force will be displayed on the LCD screen as a percentage of
the maximum available force. (100% = 50 Psig = 245 Ibs. =1,090 Newtons)
Release the head advance control(s) to terminate measurement.
Because of the characteristics of the piezoelectric load cell, the display will be
accurate only if the temperature remains constant and the period of
measurement does not exceed 30 seconds. If a 30 second duration is
exceeded, release the head advance control and repeat the procedure above.
CLEAR PARAMETERS
To cancel all variable parameters and release keypad security, press the
INFO and F TRIGGER keys simultaneously when “SONICS & MATERIALS”
appears on the LCD screen at start-up. The power supply will return to normal
Force Trigger Operation with Delay Triggering mode.
All keypad LED’s will light up and stay illuminated until the INFO and F
TRIGGER keys are released and the unit is turned Off.

or the value “0%,” will be
displayed.
