Connecting/replacing probe Every probe has its own identifier, consisting of a probe code (e.g. D-FN) and the se- rial number. When a calibration is assigned to the batch, the probe identifier is auto- matically saved in the batch. This ensures that for the batch, a measurement can be performed only using the probe that has the same identifier as the one saved in the batch.

Replacing the probe – connecting a different probe You can replace a defective probe with a new probe of the same type or connect a different probe type to the one previously used. ATTENTION – Data loss If a new probe is assigned to a batch, all previous measured readings of the batch will be lost since the measured readings previously stored in the batch were measured using a different probe and a different calibration.
Page 38
The menu page displays the probe identifiers of the two probes: the old one previously assigned to the batch, and the connected new probe. 5. Assign the connected probe to the batch: OK. A message tells you that a calibration still needs to be assigned to the batch. 6.
Settings for measurement In order to measure, you need a batch (measuring file). Settings, such as those for the measurement procedure are saved in the batch, e.g. specification limit monitor- ing and measuring mode. The link to the calibration to which the measurements are referenced is also stored in the batch file.
To deactivate specification limit monitoring > Batch Modify > OK > Limits > OK > Off > OK Parameter is activated: 2. Exit the menu: , specification limit monitoring is deactivated. Activating/deactivating offset function You can correct the measured reading by a pre-defined offset value. The actual mea- sured reading less the offset value is displayed.

Measure Notes on measuring The information for precision (remaining deviations from precision to mea- sured reading) and repeatability (repeated standard deviation) applies for the ambient and reference piece temperatures at the time of the calibration. The values for precision and repeatability may be higher than the values indicated in the data sheet if the temperatures during the measurement deviate from the ambient and reference piece temperatures during the calibration.
Handling the probe In addition to the calibration, the way in which the probe is placed on the surface is also crucial for a precise measurement. Measured reading acquisition via the probe. Important notes for correctly handling the probe during the measurement Always hold the probe at its grip sleeve.

Calibration The term "calibration" is used in this Operator's Manual as a general term for deter- mining the deviation from a reference value, adjustment and correction: calibration of the gauge using calibration standards to adapt the measuring system (gauge and probe) to the measuring application at hand.
Position of the measuring position on the specimen, such as distance from the edge, hole, platform, or step Surface roughness Overview of calibration methods Zero (zero point, calibration step Zero) This is the simplest type of calibration and is used to calibrate the gauge to a refer- ence point, the base material, which is called zero here (zero point).
Please observe the following information on calibration/ recalibration The reference piece and specimen must have the same base material proper- ties. The positions of the measuring position on the reference piece and on the spec- imen to be measured must be roughly the same (curvature, distance from the edge, hole, platform, and step).
Calibration – when is it necessary? New calibration – when is it necessary? When there is a new specimen, the properties for which no calibration has yet been created. In this case, you have to record the influencing variables with a new calibration in order to compensate for them when measuring.

4. Did you deactivate the lock function in step 2.? • Yes: Reactivate the lock function, function is activated: • No: Continue with step 5. 5. Exit the menu: , the function is now activated/deactivated. Calibration - reset You can reset a calibration and delete all the correction values (coating thickness) of the selected calibration.
Creating new calibration In the following cases, you have to record the influencing variables with a new cali- bration in order to compensate for them when measuring. When there is a new specimen, the material properties, geometry and coating thickness range for which no calibration has yet been created.
Calibration - assigning/changing names Assign a unique name to the calibration (calibration method, material designation, batch no., …), example: Z+1F EN AW 6082 or Z EN AW 6082. Keep in mind that many calibrations involving different calibration methods for different base materials can be stored in the probe/DMP-F probe adapter. A unique name makes it easier to select and assign the desired calibration to a batch.

The check is based on the measurement uncertainty (tolerance) specified for the calibration standard (calibration foil) used during the control measurement. To be able to check a calibration, you have to enter for this calibration the measurement uncertainty or tolerance for the calibration standard you want to use for the check (control measurement).

13.8 Reducing electromagnetic interference on the measurement When the magnetic induction test method is used, the electromagnetic interference radiation from the local mains voltage can influence the coating thickness measure- ment. Such interference radiation can occur close to transformers, for example. When the local mains frequency is selected, the gauge compensates for this inter- ference.
Service 14.1 Probe – count rate recording/display For error analysis, it can be helpful to view the count rates delivered directly from the probe. Our experts can use the count rates shown in the display to draw conclu- sions about the status of the probe, for example, and propose potential solutions. The count rates are measured and displayed in a service area, and this does not af- fect the batch.
