Using the stethoscope function
The stethoscope function is useful for detect-
ing machine sound irregularities, such as load
shocks and scraping. It is recommended to use
a shock pulse transducer with probe or a vibra-
tion transducer with probe tip or magnetic
foot. Installed transducers can also be used.
Connect your headphones to the output
connector (1). Open one of the measuring
techniques under Speed, Shock Pulse, Vibra-
tion or Temperature. Press MENU, select
‘Stethoscope’ (2) and press ENTER.
Source is the transducer input you intend to
use. Select with the UP/DOWN arrow keys and
press F1 (or ENTER) to confirm.
Hold the transducer against the object. Use
LEFT/RIGHT arrow keys to adjust the volume
(4).
NOTE! Setting the volume to the maximum
level may harm your hearing.

You can filter out high or low frequencies with the high
pass/low pass filter (5) at 500, 1000 or 2000 Hz. Press the
DOWN arrow key and select filter with the LEFT/RIGHT
arrow keys.
When a shock pulse transducer of type 40000 is used,
you can select ‘High frequency mode’ (6). ‘High frequency
mode’ moves frequencies above the audible down to
the audible frequency range. Activate/deactivate ‘High
frequency mode’ with the ENTER key. Adjust the amplifica-
tion (7) with the LEFT/RIGHT arrow keys.
The ‘High frequency mode’ is always activated when using
transducers of type 42000 and 44000. Vibration transduc-
ers are working in the audiable frequency range and ‘High
frequency mode’ (6) can not be used.
To select source (3), press F1. To return to the measuring
technique window, press the BACK key.
