1. Remove the top of the carrying case by unlatching the clamps located on two ends.

The USP-100A is mounted on the base of the carrying case.

2. Place the USP-100A on a stable and level surface. Avoid air currents and

mechanical vibrations. Level the unit.

3. Loosen the transducer positioning clamp and move it out of the way, remove the

cone target from the clips where it is normally stored. Place the tank on the rubber

circle.

4. Fill the test tank to ¼ inch (6.4 mm) below the top of the tank liner with fresh

degassed water at a temperature of 24.0 ±3.0 °C (75.2 ±5.4 °F).

5. Plug the AC Adapter into a power outlet, and plug the cord into the power jack at

the rear of the unit (unless operating from battery power).

6. Lower the cone target into the concentric target support sleeve located to the

back/left of the test tank (small tube inside of larger tube), while simultaneously

placing the cone target into the tank. If the cone can swing in an arc, it is not down

far enough. Tip the rod back and forth slightly to fully engage the rod. Press the

On/Zero button.

7. To avoid introducing air into the degassed water, insert the transducer at a 45°

angle. Then position so it is facing the target ⅛ to ¼ inch (3.2 to 6.4 mm) below

the water level, parallel to the water surface, and directly above the center of the

cone. Check the transducer surface for uniform wetting (no air pocket or bubbles

should be on its surface).
