Introduction
Thank you for purchasing an ultrasonic hardness tester from PCE Instruments.
The ultrasonic durometer is a device, based on a patent filed 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 different 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 significantly different from before, if the ultrasonic sensor has already performed
a major amount of measurements, or if the measurement of a defined calibration object shows a
divergent.

Safety notes
Please read this manual carefully and completely before you use the device for the first time. The device
may only be used by qualified personnel and repaired by PCE Instruments personnel. There is no
warranty on damages or injuries caused by non-observance of the manual.
-
The device may only be used in approved temperature range
-
The opening of the case should only be done by qualified personnel of the PCE Instruments.
-
The instrument should never be placed with the user interface (e.g. keyboard side on a table)
-
You should not make technical changes on the device
-
The appliance should only be cleaned with a damp cloth / use only pH-neutral cleaner
-
Do not shake the device since internal components may get damaged.
-
Do not scratch objects with the diamond.
-
Do not disassemble the unit. Otherwise the warranty will expire.
-
Do not use the instrument under inflammable air environment, otherwise it may take fire or
explode.
The ultrasonic hardness tester is a precision instrument that must be used with extreme care to avoid
damage and associated measurement error.
Remove the diamond indenter mentioned above for about half a second after each measurement and
then make a new measurement. Otherwise, the device cannot resonance between the indenter and a
single sample in a short time.
Please ensure that after each use, the device is always kept in the respective carrying case. Avoid
accidents and collisions.
Do not disconnect the probe from the main unit, since otherwise the device loses its functionality.
Do not use the product near flammable gas, as this could result in fire or explosion.
