1 Introduction
Thank you for purchasing a machine PCE-S 42 from PCE Instruments.
This electronic stethoscope is a new high-performance maintenance tool as well as an economic
instrument used to locate bearing or mechanical noises. It is particularly applicable to use in a noisy
environment to detect and maintain hidden trouble of equipment at its early stage, so that the normal
operation of equipment can be assured and the huge economic losses arising from equipment breakdown
can thus be avoided.
The electronic stethoscope is supplied with a highly sensitive probe which can effectively locate the parts
of the machine where the noises come from, such as the trembling sounds of valve tremor, tappet
vibration, loose piston, vibrations of gears and pumps, even the noise from the operation of the solenoid
of relay. Moreover, it can also detect and monitor the flow and clogging of liquid, operating status of all
kinds of motors, internal-combustion engines, diesel engines, engines and domestic appliances, as well
as the running state of automatic running water system in industrial and mining enterprises.
It is widely applied in the watercraft industry, automobile industry, chemical industry, metallurgy industry,
machine tools, household electrical appliances and machinery industry.

5.1 General use
- Attach the probe of proper length to the front-end of the instrument according to your needs and
screw the measuring tip firmly into the thread.

size of which can be adjusted.
- Switch on the stethoscope by pressing the ON/OFF button, as well as the machine to be tested,
touching the part of the machine to be tested with the measuring tip.
- The instrument is working properly when the lower LED power indicator lights up in blue colour.
Press the volume control once to increase the volume to hear sounds.
- The instrument will switch off if the volume button has not changed for 2 minutes.
- If the noise becomes louder when you increase the volume, this indicates that the instrument
works normally. Adapt the volume to your requirements by means of the arrow keys. Please note
that the headphones are also equipped with a volume control.
- Three LEDs indicate the volume level which is passed on to the headphones. The LED which is
closest to the measuring tip indicates that the maximum volume is reached. There are 32
different volume levels. The instrument will switch to automatic mode automatically if you push
and hold the button longer than 30 seconds.
- When moving the probe to a new position, it is easy to judge the distance of sound to the noise
source.

5.2 Low-battery indicator
The lower LED will keep flash to show low battery voltage. The instrument can still work but the quality of
the measurement will decrease.
5.3 Hearing protection function
The user does not always notice that the noise he/she hears is bad for the human ear. Therefore, this
mechanical faults stethoscope is designed with a function to control the volume below the international
environment noise standards.
