1. Place the SECULIFE UP on a stable and level surface. Avoid air currents and
mechanical vibrations. Level the unit.
2. Loosen the transducer positioning clamp and move it out of the way. Position the
tank on the rubber circle.
3. 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).
4. Plug the AC Adapter into a 120 VAC, 60 Hz power outlet and plug the cord into the
power jack at the rear of the unit (unless operating from battery power).
5. Lower the cone target into the concentric target support sleeve located behind 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 -
Off
button to zero the unit.
6. 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).
7. Allow 5 minutes for the scale to stabilize. With no ultrasonic power applied to the
transducer, press the ON/Zero -
Off
button to zero the unit.
8. 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 SECULIFE UP should read 1.00 ± 0.10
grams. Change the units to the watts (Custom) mode by pressing and holding the
Print Unit button until “C” is displayed, the release. The unit should read 14.65
watts ± 0.2 watts. 1 gram is equal to 14.65 watts.
9. Remove the 1 gram weight. Press the ON/Zero -
Off
button to zero the unit.
