6 Important notes (read before commissioning!)
Danger! Do not operate in an explosive environment: The device must not
be operated in explosive environments. Observe the safety regulations that
apply to you.
Regularly check display accuracy: In order to prevent influences on the
measurement result that cannot be detected in any other way, the display
accuracy should be checked before starting measurements (and from time to
time during longer measurements) using the test block (art. no. 1713.006)
included in the delivery. The proper function of the test system can be tested
by means of regular control measurements.
Protective disc: A thin plastic disc is glued to the sound outlet side of the
probe, which protects the sound outlet surface and ensures that the probe fits
well in the bayonet mount on the gearbox. Before inserting the probe into the
bayonet mount, ensure that the adhesive is intact and the plastic disc is
undamaged.
Batteries: If the instrument is not to be operated for a long period of time,
please remove the inserted batteries to avoid any potential damage as a result
of leaking batteries.
7 Instructions for use
Coupling: The reliability and accuracy of all measurements depends, among other
things, on how well the probe is coupled to the workpiece to be measured. Follow
the instructions for attaching the probe to the gear housing (see section 11.3).
Before applying the coupling agent, remove any debris or other deposits from the
contact surfaces of the probe and the probe holder in the oil sump.
Coupling symbol: Always make sure that the coupling symbol shows a fully
attached probe (see section 11.4.3). Should the measured value fluctuate or the
coupling symbol constantly change, you should improve the coupling (unscrew the
probe from the holder, clean the contact surfaces and screw the probe with
coupling agent back in again) and confirm the measured value with comparative
measurements.
Voltage monitoring: The ECHOMETER monitors battery capacity and
automatically switches off if the supply voltage is insufficient. The settings are
retained when the instrument is switched off.

11.4.5 Regular control measurements
The measurement quality must be checked at the beginning of a work shift or
once a day (and in the case of longer measurements also during measurement
breaks) using the supplied test block. Any devices with which a proper control
measurement cannot be carried out must be shut down and repaired before
further use.
Image
15: Measurement on the test
block as regular control measurement
•Ensure that the test block used is clean
and without any signs of damage or wear.
•
Ensure that the temperature of all
components involved in the control
measurement is within the range of 10 °C
to 30 °C (50 °F to 86 °F).
•
Switch on the device.
•
Apply a small amount of coupling agent to
the front of the test block or to the sound
outlet of the probe (position 1 in Image
15Image 15Place the probe on the test
block.
•
The device works properly if the
measurement on the test block
produces a measured value in the
range 24 mm to 26 mm (25 mm ±
1 mm).
Recommendation: The control
measurement should be performed
between 15 °C and 25 °C (temperatur
e for
environment, device, test block, coupling
agent, etc.)!
The measured value cannot be
determined with a mechanical length
gauge, e.g. a caliper gauge.
The table at the end of this manual
(section 23) can be used to record the
regular control measurements. If there is
not enough space, it is recommended to
copy an empty table page and use it for
the recordings (a PDF file of this manual
can be found in the download area of our
website www.karldeutsch.de).
To ensure seamless traceability, make
absolutely sure that the records are not
lost!

15 Temperature influence
The speed of sound of materials changes with temperature. This applies both to
the test material and to the search unit with its protective layer and/or plastic flow
path.
The temperature sensitivity of the measured values is stored in the Mercedes-
Benz diagnostic device and is compensated there.
16 Replacing the protective disc on the sound outlet surface
The sound outlet of the probe is protected by a transparent plastic disc (see Image
8, position 2).
Damaged protective discs must be replaced in order not to influence the
measurement quality.
•Two self-adhesive replacement protective discs (art. no.: 1930.010) are
included in the scope of delivery of the device.
•Completely remove the remains of a glued-on protective disc before applying a
new protective disc.
•Only use alcohol, e.g. isopropanol, to clean the sound outlet surface.
Image 17: Remove larger residues only
at an acute angle (as parallel as
possible to the sound outlet surface)
(left)
•When removing larger residues,
ensure that the angle of removal is
as acute as possible (see Image
17) in order not to damage the
sound outlet surface!
•The adhesive side of the discs is
protected with a white foil. Remove
the foil before sticking it on by
carefully separating the foil and the
adhesive surface with a sharp
object (knife, scalpel or similar)
