1 Introduction
Thank you for purchasing an ultrasonic hardness tester from PCE Instruments.
The ultrasonic durometer is a device, based on a patent led in 1961. Therefore the hardness
measurement is performed through a diamond placed on a spring. Due to its design and measurement
method, the ultrasonic durometer allows a simple and non-destructive analysis of metallic objects. The
ultrasonic durometer enables measurements on various construction parts, since it is programmed to
measure with dierent SI-units, the most common of which are the hardness scales according to
Rockwell, Brinell and Vickers. Featuring a RS-232-interface the ultrasonic durometer PCE-5000 can be
connected to a computer in order to read out and print out the measured data. The ultrasonic durometer
allows a detailed overview of all the data, since it can record even the thresholds as well as mean values.
The mean value is automatically generated as soon as more than one measurement is performed with
the ultrasonic durometer PCE-5000. Its design allows reaching even locations that would be otherwise
hard to reach, and it allows reviewing and reading the values comfortably at its graphic display. Due to an
option to calibrate, the ultrasonic durometer can be always calibrated by the user at any time. A
calibration might be necessary, if for example the last measurement was more than three months back, or
when the environment is signicantly dierent from before, if the ultrasonic sensor has already performed
a major amount of measurements, or if the measurement of a dened calibration object shows a
divergent.
Range of use

3 Specications
There are dierent kinds of methods for measurement of hardness:
Brinell, Rockwell, Vickers, Leeb, etc. are usually used.
Rockwell and Brinell test forc with larger test loads and large stamps what often leads to visible s e
damage to the material surface. The hardness-measuring of heavy work pieces, built- machinery and in
permanently assembled parts is therefore relatively dicult.
The ultrasonic hardness tester PCE-5000 uses the Ultrasonic Contact Impedance procedure to carry out
comparative hardness measurements for test pieces, with the advantages of a highly accurate, ecient,
portable and non-destructive measurement with simple operation.

Note: The table only shows the values for the 20 N probe.
Condition of the surface
The applied test force (i.e. the selected UCI probe) must not only match the application but also the
surface quality and roughness of the material. While smooth, homogeneous surfaces with low test loads
can be measured, rougher surfaces and coarse-grained require measurements with high test loads.
However, the surface must always be free of contaminants (oil, dust, etc.) and rust.
Dimensions and weight of the part to be tested
From the above analysis, all probes request coating layer or surface layer less than 1 mm. The hardness
value will change if there is resonance. The highest value of vibration is the elastic oscillation, where
some actions can be made in order to restrain these. To do so the piece has to be put on thicker metal.
Rubber and oil can restrain elastic waves. It is recommended to use pieces that have a thickness of 2…3
mm and a size, which is not less than 5 x 5 mm.
Also the weight of the material is important. Depending on the weight certain preparations have to be
made:

7 Operation
7.1 Initial operation
Connect the angle plug of the 8-pin data cable to the 8-pin connector of the probe together. If you hear a
clicking noise, the device is in the correct position. Now connect the other end of the 8-pin data cable to
the 8-pin connector of the ultrasonic hardness tester. Match with the positions of the groove and put them
together. When you hear a clicking sound, the connections are correct.
7.2 Measurement
To perform a measurement, follow these steps:
1. so that the power supply is Press “Power” , and move the “ON/OFF” switch to “ON”,
turned on. You will reach the main menu then.
2. - -button. The Press the “Scale” Button to select the measurement scale and press the “ETR”
measurement mode will start then. After that the symbol is displayed.
3. Hold the probe with both hands vertikal to the test object. Press down the inspection atamp until
the measurement tip is not visible anymore and the protective ring is lying at on the test
material.

4. Hold the probe for about 2 seconds in this position until the measurement is complete. The
device then sends a signal, which states that the measurement is complete and the measured
values can be read from the display. The rst reading is not included in the determination of the
average value.
Note:
- Normally ve measurements, made within 645 mm² sufce to get usable results. If the test
material is very inhomogeneous you should make more than ve measurements to get usable
results.
- In case you changed the amount of the single measurements in the settings, you need to stick to
that setting. Otherwise the measurement is not completed.
- The ultrasonic hardness meter is a highly precise instrument. Take care to always hold the probe
with two hands in the vertical position. Do not put the probe under dierent pressure and take
care that no impacts occur during measurements. When lifting the probe pay attention that you
do not scratch the material with the diamond.
- Check the accuracy and the repeatability regularly. Use the calibration standard which is
delivered with the instrument. To check the characteristics you need to perform 5 measurements
as described above and compare the results that are noted on the calibration standard. If the
deviations should be too big, you need to calibrate the instrument.

9 Calibration
9.1 Reasons to calibrate
- If the readings are stable in the process of reviewing the durometer with the reference block, but
the nominal value of the reference hardness block is dierent.
- After a long storage (more than 3 month)
- After intense using (more than 200.000 measures with the probe
- When operating conditions have changed considerably (ambient temperature, humidity)
9.2 Preparations
For a Rockwell C (HRC) calibration you need two dierent calibration standards:
- 25 ± 5 HRC
- 65 ± 5 HRC
Note: If you do not use the whole measuring range of Rockwell C (e.g. only from 20 … 40 HRC) you may
also use a 25 ± 5 and 45 ± 5 HRC calibration standards. The same goes for Vickers.
Note: In special cases, only one block per calibration is necessary.
9.3 Calibration procedure
9.3.1 Calibration with two calibration standards
Press “MENU” in the main menu. Move to “test setup” and choose the “Calibration setup”. Insert the
password (“888888” is the preset standard) and press “ENTER”. You will now see the following display:
Choose by using the arrow keys one free storage slot. Then press “MAT”. Now you need to perform six
measurements on the soft calibration standard. After doing so the mean value will be shown at “TEST L”. -
Press “MAT” again and the right-arrow key afterwards. Now you have to make six measurements on the
harder block. The mean value will be displayed at “TEST H”.-
Now press the “MENU” key to enter the nominal value of the calibration standards. Use the arrow keys to
do so. With the “SCALE” key you can set how much the value should be increased or decreased. Press
“MENU” to finish the calibration. The new settings are saved and will be set automatically.
Note: If there is an arrow upwards or downwards displayed during the calibration, the measured value is
above or below the hardness scale.
9.3.2 Calibration with one calibration standard
The calibration with only one calibration standard is similar to the calibration with two standards. The
dierence is that - -you do not calibrate the “TEST H” part. Press the “MENU” key after “TEST L” calibration
and enter the nominal value. Finish the calibration by pressing “MENU” again.
Manual
19
9.3.3 Batch-Mode
Within the calibration settings, you can also enter the tolerance thresholds. If you have entered the upper
and lowest value, the instrument shows if the measured value is within that area every time you measure.
If the value is within that area the instrument shows “PASS”. If the value is not within that area it will
display “NG”.
To set the tolerances, use the arrow down key after you have set the “TEST L” and “TEST H” values. You - -
will now get to the points “UP” and “DOWN”. Up stands for the upper threshold, DOWN the lower value.
To set the values is made equal to setting “TEST L and “TEST H”. - -
