Safety instructions
Must be read before starting up the device!
Warning:
•
Switch on instrument without head set on. Monitor the display that
there are only green bars shown. In case of yellow or red bars,
reduce sensitivity by turning the sensitivity wheel.
•
When detecting ultra sonic signals in electrical systems ensure that
you keep sufficient safety distance to avoid electrical shocks!
•
Do not point into the eyes with the laser!
•
Observe permissible storage, transport and operating
temperatures.
•
Improper handling or use of force cancels all warranty claims.
Operating principle
LD 300 ultrasonic leak detector allows maintenance personnel to confirm a
diagnosis on the spot by being able to clearly discriminate among various
equipment sounds.
This is accomplished by an electronic process called 'heterodyning' that
accurately converts the ultrasounds sensed by the instrument into the
audible range where users can hear the audible signal through a
headphone.
The high frequency, short wave characteristic of ultrasound enables users
to accurately pinpoint the location of a leak or a particular sound in a
machine.
The basic advantages of ultrasonic instruments are that they can easily
locate leaks, provide advanced warning of impending mechanical failure
and can be used in loud, noisy environments.
LD 300 integrates a laser pointer which helps to spot the leak from
distance.
In unpressurized systems an ultrasonic tone generator can be used whose
sound will leak through small openings.
