Description
The Car Cylinder Stetoscope is a high performance maintenance tool which is particularly suitable for use in machine noise detection. By using it, you can easily detect and find the early hidden trouble of a machine so that you can service the machine in an early time to ensure the machine's proper operation and avoid any damage and economic loss.
The Car Cylinder Stetoscope consists of IC circuit and transistor. It features a small size and a light weight. It is very useful and easy to use. It is a powerful tool for a maintenance man.

Functions
The Car Cylinder Stetoscope can be used as follows:
✨ Rapidly detect the machine noise from engunes, an air cylinder or an automobile, and exactly find out the malfunction position.
✨ Identify the abnormal noise from an engine or a motor to avoid accident.
✨ Monitor the automatic assembly line to ensure proper operation.
✨ Used in chemical industry to check whether the liquid in a pipe is flowing or blocked.
✨ Detect abnormal noise in all kinds of boilers or reaction containers.
✨ Monitor the working of all kinds of axletress.
✨ Monitor the working of a ship.
✨ Used in the maintenance of various vehicles.
✨ Used in the maintenance of various household appliances.


The Car Cylinder Stetoscope probe has a high-sensitivity so that you can use the unit to detect and locate the position where the machine's certain noise come from. All kinds of noise can be detected, for example, valve's quiver sound, tappet's tremolo, a loose piston's sound, tremolo of gear or pump and sound of relay solenoid. In addition, it can also be used to judge whether the liquid in a pipe is flowing or blocked, as well as to judge the working conditions of various motors, internal-combustion engines, engines, engines, household appliances, the automatic assembly line, and so on.

Operation
1. Slide the battery cover out, install a 9V(6F22)battery, rejoin the cover.
2. According to the actual situation, select and install the long probe or the short probe.
3. Wear the earphone. Insert the plug of the earphone to the earphone jack.
4. Turn the Volume/Power Switch to switch the stethoscope on and the Signal LED lights to indicate that the unit works.
5. Adjust the Volume/Power Switch, a buzz sound indicates that the stethoscopeis good.
6. Lightly the probe with your hand,you will hear the response sound from the earphone,this means that you can begin your detection.
7. You can adjust the Volume/Power Switch for a desired volume. the end of the probe to the desired positions of the object which you want to detect. Pay attention to the change of the sound from the earphone. Finally you can locate the position where a certain noise come from. According to the experience and the relevant knowledge, you can find the early hidden trouble or the position where a malfunction exists.
8. Normally a short probe can meet your need, if necessary, you can use the long probe.

Car Cylinder Stetoscope can be widely used in ship, automobile, chemical manufacture, metallurgy, machine, household appliance and many other fields.
