10. After the display’s stability indicator is shown, activate the DUT and record the
measurement. Rezero before each measurement and take your power reading
when the display has stabilized. 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.
11. Determine the maximum peak power with the maximum duty cycle and pulsed
output settings with the equation:
PAVE = Pp / Rtpa
PAVE
= calculated average power
Pp
= Peak Pulsed Power Setting on unit under test
Rtpa
= Ratio of Temporal Peak to Average Power (from each manufacturer)
12. To calculate the watts/cm² output, take the total watts reading from the unit and
divide by the area. The area is π
D
2
÷ 4
(
D
is the diameter of the transducer) if the
transducer is smaller than the cone. Otherwise, use (8.2 cm) the cone’s diameter
as the area.
13. When finished, turn the unit off by pressing and holding
ON/Zero/
Off
button until
OFF is displayed, then re-lease. Unplug the SECULIFE UP, empty the tank and
dry. Dry target cone. Place in foam in case along with power adapter. Position
transducer holder over tank. Position transducer holder over tank positioner. Close
case and latches.
