8. Allow 5 minutes for the scale to stabilize. With no ultrasonic power applied to the

transducer, press the On/Zero button to zero the unit.

9. Check response by placing the 1 gram weight on the arm of the cone target (the flat

part that is out of the water). The USP-100A should read 1.00 ±0.10 grams.

Change the units to the watts mode by pressing and holding the Unit button until

“CUSTOM” is displayed then release. The USP-100A should read 14.6 ±0.2 Watts.

10. Remove the 1 gram weight.

11. After the display’s stability indicator is shown, activate the DUT and record the

measurement. It is a good practice to take three readings and average them. If

measurement conditions are not stable, use the grams mode and multiply the

readings by 14.65 to obtain Watts.

12. When finished, unplug the USP-100A, empty the tank, and place the dry target

cone in the tank for protection.
