Operating Instructions
1.
Having assembled the balance and connected the mains adaptor to
a suitable supply, switch on the balance.
2.
The balance executes a short self-test routine, then displays zero.
(0.000 g)
3.
Press Enter to select the customised display (watts). DO NOT
press Select – see previous page.
4.
Position the ultrasound transducer being tested so that the active
face of the transducer is just below the surface of the water, and so
that the sound emitted from the device will hit the centre of the
target cone. The transducer may be held in place using a
centralising plate and quick release attachment if it is an EMS
device, otherwise use the universal clamp supplied.
5.
Make sure that there are no air bubbles trapped beneath the
transducer.
6.
Zero the balance by pressing one of the Tare buttons. (The balance
should be re-zeroed before each measurement.)
7.
Turn on the ultrasound output and wait for the output power
display in watts to give a steady reading.
8.
Make sure that no air bubbles form beneath the face of the
transducer during use and that the transducer or its cable do not
obstruct the frame which supports the target cone.
