Information about the device

Device description
The device BB30 is used to determine the coating thickness on ferromagnetic and non-ferromagnetic metal surfaces. The measuring device functions according to the magnetic induction principle (for coatings on ferromagnetic surfaces) or the turbulent flow principle (for coatings on non-ferromagnetic surfaces).
The measuring head can either be connected directly to the device or alternatively via an extension cable.
The scope of delivery includes a set of calibration accessories (FE, NFE, various layer thickness samples) for easy calibration.
The device can be connected to another terminal device via Bluetooth. In combination with the Trotec MultiMeasure Mobile App, there are numerous possibilities for evaluating and displaying the measured values.
The measurement results can be displayed and saved on the terminal device either numerically or in form of a chart. Then, the measurement data can be sent in PDF or Excel format.
The app also includes a report generation function, an organiser function, one for customer management and further analysis options. Moreover, it is possible to share measurements and project data with colleagues in another subsidiary. If MultiMeasure Studio Professional is installed on a PC, you can even use report templates and ready-made text blocks for various fields of application to turn the data into professional reports.

When the device is not being used, observe the following storage conditions:

• dry and protected from frost and heat
• protected from dust and direct sunlight
• For storing the device, use the transport case included in the scope of delivery in order to protect the device from external influences.
• the storage temperature complies with the values specified in the Technical data

Operation

Inserting the batteries

Insert the supplied batteries before first use.
Note
Make sure that the surface of the device is dry and the device is switched off.

1. Push down the clip at the cover of the battery compartment (5) and remove the cover.
2. If applicable, remove old batteries from the battery compartment.
3. Insert the new batteries in the battery compartment with the correct polarity.
4. Put the cover back onto the battery compartment and press the side with the clip down until it clicks into place.

Connecting the extension cable

You can connect the extension cable for the measuring head so as to reach poorly accessible locations.
To do so, please proceed as follows:

1. Disconnect the measuring head (3) from the device by pressing both release buttons and pulling the measuring head off.
2. Connect the measuring head side of the extension cable (7) to the measuring head (3). Please note that there is only one position that permits the extension cable to be plugged in.
3. Connect the device side of the extension cable (6) to the device by pressing both release buttons and attaching the connector. Please note that the connection can only be established in one way.

Switching the device on

Info
Note that moving from a cold area to a warm area can lead to condensation forming on the device’s circuit board. This physical and unavoidable effect can falsify the measurement. In this case, the display shows either no measured values or they are incorrect. Wait a few minutes until the device has become adjusted to the changed conditions before carrying out a measurement.

1. Press the Power button (8) for approx. 2 seconds.
   The display will be switched on and the device ready for operation.

Device calibration

Carry out a zero-point calibration before each measuring operation.
You can perform the calibration e.g. at an untreated or uncoated spot of the object to be tested or use the set included in the scope of delivery.
Info
Please bear in mind that the device at hand is a precision measuring device that can determine coating thicknesses of no more than a few micrometers (1 µm is equivalent to one-thousandth of a millimeter).
The surface condition of most measuring objects is hardly ever perfectly even and homogeneous, even though it might appear differently to the naked eye. Observed under the microscope, even the smoothest surface looks much like a mountain and valley landscape. The teensiest of scratches, cavities or contaminations can therefore already have a negative effect on the expected measurement result, seeing as they will also be a part of the measurement to a greater or lesser extent. It does, however, not affect the accuracy of the device. Even after the calibration unexpected measurement deviations of a few micrometers always have to be regarded in this context.
Hence it is important to handle the supplied calibration accessories with care to avoid scratches and dirt on their respective surface as far as possible.

Zero-point calibration

1. Press the Up button (2) for approx. 3 s.

   • The following message will be displayed:
     Zero Reference
     Place Probe

2.  Position the sensor (4) on an uncoated spot of the material to be measured. The measured medium is to be identical to the coated material to be measured thereafter in terms of material composition, shape and surface condition.

   • The measurement will be acknowledged with an acoustic signal.

   • the measured value will be indicated on the display.

   •  The following message will be displayed:
     Zero Reference
     Lift off Probe

   • Another acoustic signal will be emitted, then the calibration is completed.

Carrying out a measurement

Carry out a zero point calibration before each measuring operation.

1. If you want to save your measured values, use the Up and Down buttons (2) to select a group (Group (1) to
