1 Introduction

Thank you for purchasing a surface texture meter from PCE Instruments.

The surface texture meter PCE-RT 10 is a small, light device with a very simple navigation. Despite the

fact that the device functions on a very complex and elaborated level, the measurement results can be

gained very easily and in a comfortable way. Due to a high insensitivity the device has a long lifetime.

This device is calibrated according to ISO, DIN, ABSI and JIS standards. The surface texture meter can

be applied for various mechanical manufacturing processes as controlling equipment. The device

indicates all calculated measurement results on its LCD display at any time. In order to measure the

roughness of a surface, the sensor has to be placed onto the surface. Subsequently, the sensor moves

smoothly in the lead on the surface. Now the device will calculate the measuring values. Thus the

indicated values are a result of the sensor's movement, while it is induced with electricity. The fast DSP

processing supports quick measurements results, which are then shown on the surface texture meter's

display. If the instrument is not used for five minutes, it will turn itself off automatically.

2 Safety notes

Please read this manual carefully and completely before you use the device for the first time. There is no

warranty of damages or injuries caused by non-observance of the manual.

- The instrument may only be used as described in this manual. If it is not used in the described

way it may cause injuries or break.

- Only use the device in the prescribed ambient conditions. Protect it from direct sunlight, fluids and

high humidity.

- The instrument may only be used by qualified personnel and repaired by PCE Instruments

personnel.

- Do not place the instrument on the user interface since scratches may appear on the interface.

- Do not make any technical changes on the device.

- The appliance should only be cleaned with a damp cloth / use only pH-neutral cleaner.

- Only use the tester with dry hands.

- The instrument can only be used with and replaced by accessory supplied by PCE Instruments.

- The measuring instrument cannot be used in explosive atmospheres.

- If the tester is not used for a longer period of time the batteries should be taken out of the device

in order not to damage it.

4.3 Measuring procedure

4.3.1 Preparations

1. Switch on the device to check the battery level

2. The device will automatically set the conditions of the last measurement. Because of that all

settings should be checked properly.

3. In order to check the settings the parameter button needs to be pressed.

4. Check if the cutoff frequency is set correctly. If that is not case, press the cutoff frequency button.

To set the correct length of the cutoff frequency, refer to the table “Recommended length of the

cutoff frequency” within this manual.

5. Press the µm / µinch button to check the correctness of the measuring units.

6. Clean the surface you want to measure in order to avoid faulty measuring results.

7. The device needs to be placed correctly on the surface. This is shown in the figure below. If it is

not set up correctly the measured results may be faulty.

8. The sensor of the instrument needs to be placed on the surface in an angle of 90 °.

4.3.2 Perform measurements

Press the Start button when all preparations are made. The display shows “- - - -“ while the measurement

is made. After the selected area has been detected the probe only moves backwards to the position from

where measurements are started. After this point has been reached, the measured value is displayed on

the screen. Now it is possible to view the results in Ra or Rz by simply pressing the Parameter button.

4.3.3 Set the measurement length

The measurement length is set by making use of the Calibration button. Press the Calibration button until

the display shows “LEN”. You can now choose length “1” and “2” by pressing the Up or Down button. The

settings can be saved by pressing the Start button.

4.3.4 Calibration

To calibrate the device, press the Calibration button. “CAL” will show up in the display. Now place the

device on the calibration plate and press the Start button. The display will show a result after

measurement has been made. You can now adjust value according to the reference value on the

calibration plate. To do so, use the Up / Down button. When the correct value has been set, switch the

device off and on again.

4.3.5 Set Cutoff length

To set the cutoff length the Cutoff button simply needs to be pressed. You can choose between 2,5 mm,

0,25 mm and 0,8 mm.

6 Disposal

For the disposal of batteries, the 2006/66/EC directive of the European Parliament applies. Due to the

contained pollutants, batteries must not be disposed of as household waste. They must be given to

collection points designed for that purpose.
