The EP542 ultrasonic detector set is used to find leaks (e.g. in compressed air installations, vacuum installations, in tanks, on car windows etc) as well as to find mechanical malfunctions on movable parts (e.g. ball bearings, gears, etc).
The ultrasonic detection equipment EP542 works by ”listening” in a frequency band normally containing no interference and non-audible for humans (>20 kHz). Leaking compressed air or electrical flashover (sparks) generates e.g. ultrasonic.
As a mechanical malfunction feeler, the EP542 picks up interference from movable parts through a stethoscope. The stethoscope only ”listens” to low-frequency mechanical vibrations so the stethoscope can also be used in noisy areas (in noise filled areas a CE approved EP921 hearing protector can be offered as an accessory).
If the need occurs for a product with a higher ”listening” sensitivity we are able to offer the EP2400 ultrasonic detector set.
Ultrasonic:
1 . Fit the pin from the headphone into the front of the detector in the yellow plug (Phones).
2. Push the button with the text ”Ultrasound” down and hold it there.
3. Lead the sensor at the top of the detector over or past the desired parts to be examined.
4. If there is a leak, a ”buzz” will be heard in the headphone. The sound level depends on the size of the leak. If looking for a very ”small” leak close by, the directional probe can be applied to the sensor at the top of the instrument and optimum listening sensitivity is achieved.
5. Finally, make sure and seal all the leaks found at the examination - leakage costs money!Ultrasonic with EP512 sensor (extras):
1 . Mount the pin from the headphone into the front of the detector in the yellow plug (Phones).
2. Turn on EP5I2 on the button with the text "Ultrasound".
3. Check that the red lamp starts flashing.
4. Place EP512 in the tank or cabin and close.
5. At the EP542, the button with the text ”Ultrasound” is pushed down and held there.
6. Lead the sensor at the top of the detector over or past the desired parts to be examined and listen for leaks!Mechanical noise:
1 . Fit the pin from headphone into the front of the detector in the yellow plug (Phones).
2. Screw the short or the long stethoscope (depending on the task) to the top of the detector.
3. Place the stethoscope at the item to be examined.
4. At the EP542 the button with the text ”Stethoscope” is pushed down and held down.
5. Concentrate on the mechanical noise. In some cases the user has to spend some time to sort out other mechanical noises and between these e.g. hear a damaged bearing. Concentrate on strange noises and heterogeneity and remember ~ practice makes perfect!Changing the battery:
1. Unfasten the bottom with a screwdriver and lift off the plate in front of the battery.
2. Take off the contact pole, lift off the battery and exchange it with a new one.
3. The battery may only be changed to a 9 V ALCALINE or ZINKCHLORIDE battery.WE HOPE YOU ENJOY WORKING WITH EP542. May 2004 Rev 01
