1 Switching the instrument ON / OFF (valid for all instrument models except the “…-FP” models)
Note: The instrument does not have a specific ON / OFF switch.
Switching the instrument ON
The instrument will switch ON automatically when it is placed on a specimen. If the instrument is placed on
nonferromagnetic or electrically nonconductive material, the display will show the error note "Er6" and then four
horizontal bars instead of a reading.
PLEASE NOTE!
Do not power up the instrument by pressing a finger on the sensor! It may result in erroneous measurements.
Switching the instrument OFF / Auto-Switch-Off
After a certain time, the instrument will switch off automatically (OFF = when instrument’s display is empty)
You can set the period from the last measurement to the automatic OFF from the service mode.
See chapter 14 “Service Menus”, page 27.

2 Switching the “…-FP” instrument models ON / OFF
Note: The on/off operation is different to the other MP0R models!.
Switching the “…-FP” instrument ON
The ON key is the key [OK].
Switch the instrument ON by pressing the key [OK]
Switching the instrument OFF / Auto-Switch-Off
After a certain time, the instrument will switch off automatically (OFF = when instrument’s display is empty)
You can set the period from the last measurement to the automatic OFF from the service mode.
See chapter 14 “Service Menus”, page 27.

4 Measurements on coating material
Making measurements with the MP0R:
1. With the instrument switched ON, place the instrument on the specimen and wait, until the acoustic signal
sounds. The instrument will switch ON automatically this way.
2. Lift the instrument off the specimen.
The acoustic signal sounds and the reading will be displayed. Note: when lifting the instrument too early
(before the beep sound), the error note "Er6" will appear. In this case, repeat step #1.
The measurement is transmitted automatically to the radio receiver (cf. chapter 14 “Service Menus”, page 27,
menu 3, “radio transmission ON/OFF”. The transmission is indicated by the flashing radio tower symbol.
3. When measuring with an instrument which is already swiched ON, a reading will be displayed at once.
As well as with an instrument placed on the specimen and with the instrument lifted off.

5 Evaluation of a test series (Statistics function)
Prerequisite: At least two readings must be saved in the measurement data memory.
Note: The measurement data memory must always be empty before starting a test series that is to be evaluated
(cf. chapter 7 "Deleting measurements", page 15). If at least two readings are not stored in memory when you first
press RES and then [OK], the statistical evaluation will NOT start.
Statistical evaluation of a test series:
1. The display menu shows "RES". This is the default setting of the instrument. If RES is not currently shown on
the display, use the arrow key [] or [] to switch to this setting.
2. Press button [OK] repeatedly.
After each [OK], the display will change to the next statistic number (see table below).
3. Press [ESC] or do further measurements to continue a block. This allows to do statistical evaluations within a
test series.

6 Transmitting data to a computer
The RS232 radio interface integrated in the instrument facilitates the transmission of the data stored in the
measurement data memory to an optional radio receiver (order no. of US-receiver version: 603-544).
The radio receiver, in turn, transmits the data to the evaluation computer via a cable. There is a separate
operator's manual for the optional radio receiver.
Prerequisite for all following sub-chapters: Settings of service menu must be “rF = 1” e.g. the radio transmitter
is active. See chapter 14 “Service menu”, menu #3”, radio transmission, page 26.
6.1 Transmitting only the current reading
Independent of the current menu selection, each reading is radioed to the computer automatically.
At the same time, the reading is accepted into the measurement data memory of the instrument and can be
evaluated statistically.

13
6.2 Transmitting all measurement data in the instrument memory
1. Set the display menu with [] or [] to show .
2. Press button [OK].
All readings in the memory are then radioed to the PC. This is indicated by the flashing radio tower symbol.
6.3 Sending the current mean value
Prerequisite for following sub-chapters of 5.3:
Settings of service menu must be “SI = 0” e.g. mean value transmission is active. See chapter 14 “Service menu,
menu #4”, menu mean value transmission”.

14
6.3.1 Triggering the mean value transmission manually
Prerequisite: Settings of service menu must be “bL = 1” e.g. mean value transmission is active.
See chapter 14 “Service menu, menu #1”, menu point “Block length”.
1. Make desired number of measurements.
2. Set the display menu with [] or [] to show "RES”. Press button [OK]. The mean value of the readings in the
memory are then radioed to the PC. This is indicated by the flashing radio tower symbol.
6.3.2 Sending the mean value automatically
Prerequisite: Service menu settings of “bL” must be between 2 and 20.
The set value indicates the number of readings, which are collected in one block. See chapter 14 “Service menu”.
1. Make desired number of measurements.
2. Indepentently of the pre-set number of readings/block, a block mean value is radioed and a new block will be
begun.

15
7 Deleting measurements
7.1 Deleting only the last reading
1. Select the menu DEL with [] or [].
2. Press button [OK]. The last reading will be deleted.
7.2 Deleting all measurement data from the measurement data memory
1. Select the menu RES with [] or [].
2. Press button [OK].
3. Select the menu DEL with [] or [].
4. Press button [OK]. All measurement data will be deleted from the measurement data memory.

8 Normalizing
A normalization is used to adjust the measuring instrument to a measuring task.
The symbol on the display of the instrument indicates the “Normalization” operating mode.
The following items are required for performing a normalization:
•Uncoated specimen.
In geometry and substrate material, this specimen should correspond exactly to the parts to be measured.
Note: All readings in the memory will be deleted when performing a normalization.
Normalizing the instrument:
Prerequisite: Instrument must be turned ON.
1. Select the menu (normalization) with button [] or [].
2. Press button [OK]. The message "Base" (for “substrate (base) material”) appears.

17
3. Perform about 5 measurements on the uncoated specimen.
After each measurement, the current reading will appear on the display.
Note: If you want to delete wrong readings, press button [ESC]. Then, the complete data memory will be
deleted, but the normalization routine will not be interrupted. After that, perform five more measurements.
4. Press button [OK].
By pressing button [OK], the mean value of all readings will be calculated and used for normalization.
Thus, a good normalization is possible on rough surfaces as well. The mean value is set to zero.
The reading 0.00 will appear on the display.
Finished.
Note: the function „Normalization“ can be locked to protect the instrument from unintended interventions.
Cf. Chapter 14 „Service menu“. If the normalization is called while the function lock
(display: ) is active, the error note „Er29“ will appear on the display.

18
9 Calibration
The following items are required for performing a calibration: An uncoated specimen: In geometry & substrate
material, this specimen should correspond exactly to the parts to be measured and a calibration standard
(instrument-specific correction foil 75 µm (3 mils)).
Note: All readings in the memory will be deleted when performing a calibration.
Calibrating the instrument (Prerequisite: Instrument must be turned ON)
1. Select the menu with button [] or [].
2. Press button [OK]. The message "Base" (for “substrate (base) material”) appears.
3. Perform about 5 measurements on the uncoated specimen. After each measurement, the current reading will
appear on the display. (continued on next page!)
4. Press button [OK].
By pressing button [OK], the mean value of all readings will be calculated and used for normalization.

19
The mean value is set to zero. The reading 0.00 will appear on the display.
The message STD1 (that is, calibration standard # 1) appears.
5. Place the calibration foil on the uncoated specimen and perform about 5 measurements.
After each measurement, the current single reading will appear on the display.
Note: If you want to delete wrong readings, press button [ESC]. Then, the complete data memory will be
deleted, but the calibration routine will not be interrupted. In this case, repeat the test series with the
calibration foil.
6. On the display, set the NOMINAL value for the calibration standard, e.g., "75 µm". Use the arrow key [] or
[]. The NOMINAL value of the calibration standard is printed on the standard.
7. Press button [OK]. By pressing [OK], the mean value of all readings from step 5 will be used for calibration.
Note: the function „Calibration“ can be locked to protect the instrument from unintended interventions.
Cf. Chapter 14 „Service menu“. If the calibration is called while the function lock (display: ) is active, the error
note „Er29“ will appear on the display.

10 Deleting a calibration / Restoring the baseline of the characteristic
Sometimes, if an instrument does not measure correctly even after a calibration, the calibration can be deleted.
This can occur if the previous calibration has not been carried out correctly.
In such a case, the baseline of the characteristic can be restored to its original factory condition.
Note to users of the DUALSCOPEMP0R (instrument version with two measurement channels): the base line of
each of the two measurement channels must be restored separately (Fe Base and Al Base required).
Deleting the calibration of the instrument: (Instructions continued on next page)
Prerequisite: Instrument is switched ON.
1. Select the menu option (i.e., calibration) using button [] or [].
2. Press button [OK]. "Base" (i.e., “substrate material”) will appear on the display.
The instrument is now in calibration mode.
