The quantity of influences are stated with the expanded measurement uncertainty U with the expanded factor of k = 2 (defines an interval with the confidence level of 95.45 %) - according to ISO/IEC Guide 98-3:2008-09 "Guide to the expression of uncertainty in measurement".
3.1 Setup Installing batteries Setup 3 3.2 Switching on the gage ► Press the 1 s. key for approx. The main menu appears in the display or the measurement view for the batch that was open at shutdown. 3.3 Battery polarity Observe the correct polarity when inserting the batteries! Damage to the instrument The use of defective batteries or the wrong type of battery causes damage to the gage. Leaking batteries destroy the gage's electronics. ► Use only undamaged batteries.
Getting started 4 Getting started All the settings relevant to measuring the coating thickness of a coated sample 1 and the measurement readings themselves are saved in a file. Such a file is called a batch. In the batch, you define the measurement procedure, e.g. whether the specification limits are to be monitored during the measurement or whether the measurement readings are to be grouped in measurement block. In addition, you must assign a calibration (reference) to the batch in order to measure.
Settings for measurement In order to measure, you need to create and open a Batch (measuring application file). In a batch, you define the Measuring application and settings for the measurement procedure, e.g. whether the specification limits are to be monitored during the measurement or whether the measurement readings are to be grouped in measurement block. The link to the Calibration to which the measurements are referenced is also saved in the batch file.
Settings for measurement 5.1 Creating a new batch A Batch is created by selecting a Batch type. Each batch type is assigned a certain Calibration method and contains presets for the measurement process. Calibration and setup routines simplify creation of a batch. Selection of the batch type and the associated calibration method is based on the requirements of the guideline/standard or the accuracy of measurement needed. An overview and description of the available batch types can be found on page 11.
This completes the creation process for a new batch. What you can do next • Measure, see Page 23 • Assign a different calibration to the batch, see page 22 5.2 Opening a batch Before you start • The gage is switched on ( key) Opening an existing batch 1. Main Menu () > Batches 2. Select the desired batch from the list: 3. Tap on OK, to confirm your selection 4.
Settings for measurement 5.3 Assigning a different calibration to the opened batch Before you start • The gage is switched on ( key) • The desired batch is opened, the corresponding batch name appears in the colored header field Assigning a new calibration 1. ‘Main Menu () > Batch Modify > OK > More Settings > OK > Calibration Assign > OK 2. Select an existing calibration from the list: Only the calibrations whose calibration method matches the open batch are displayed. 3.
Measurement During the measurement you can also: • Delete single readings: Press the key • View the statistics of the open measurement block: Press the BLOCK key 6.1 Notes on coating thickness measurement Essentially: If the specified precision is not achieved during the measurement, you must recalibrate the probe, see page 25. Measured readings outside the specified tolerance limits are displayed in red and indicated by an illuminated red LED.

NF/FE Batch 03 (IDV) 125 115 No X Min 120 1 121 118 n s Max 2 Measurement acquisition An audible signal as well as the lighting of the signal lamp reports the measurement acquisition. The new measured reading appears in the display 3 Lift the gage Raise the gage at least 25 mm above the surface of the sample NF/FE Batch 03 (IDV) 125 µm 4 1.
Calibration The coating thickness measurement is mainly influenced by the following variables: • Physical characteristics of the base material of the sample, such as magnetizability (permeability) or electrical conductivity. • The geometric shape of the sample, such as the thickness of the base material or curvature of the sample (e.g. cylindrical shape). • The position of the measurement location on the sample: distance from the edge, hole, platform or step.
Calibration 7.1 Calibration - When necessary? • When you have a new measuring application, the influencing factors must be recorded in order to compensate for them when measuring. Recalibration - When necessary? • When the correctness of the measurement is not assured 7.2 Selecting the appropriate calibration method A measurement can only be performed if a calibration using the appropriate calibration method is assigned to the batch in the gage. A calibration method is assigned to each batch type.
Foil thicknesses that can be used: • Measurements on Fe1 base material: max. 800 µm (31.5 mils) • Measurements on NF2 base material: max. 1150 µm (45.3 mils) • Zero + 2 Foil (calibration steps Zero and two times Foil) On the one hand, a calibration with 2 calibration foils yields the best measurement accuracy in the coating thickness range delimited by the two calibration foils; on the other, however, 2 calibration foils are needed to calibrate the upper measurement range of the gage.
Calibration 7.
If measurements are to be carried out on both base materials (magnetizable, non-magnetizable), repeat the calibration with the other base material! Proceed as described in Chapter "Recalibration – Procedure". What you can do next • Switch on the calibration function Quick, page 29 • Assign the calibration to the opened batch, page 22 7.3.2 Recalibration – Procedure 1.

Calibration foil Uncoated reference part When using a calibration method with 2 foils, repeat the entire foil calibration step (steps 1 to 4) with the second foil.
Calibration- Assigning/changing names Assign a unique name to the calibration (calibration method, material designation, batch no., …), example: Cal-1Foil EN AW 6082 Keep in mind that many calibrations with different calibration methods are stored in the gage. A unique name makes it easier to select and assign the desired calibration to a batch. Procedure 1. Open the Rename function: Main Menu () > Calibrations > Name of calibration > Rename 2.
Data transfer 8 Data transfer The following data can be transferred from the gage: • Batch files into the App PHASCOPE PAINT, see page 36 You can download the app for free from the Google Play Store or Apple App Store. • Single readings in an Excel file via PC-Datex, see page 38 You can download the program PC-Datex for free from the Fischer-Homepage. 8.1 Transfer batch files in the PHASCOPE PAINT app Before you start • The PHASCOPE PAINT app is installed in the used mobile device.
• Use the PHASCOPE PAINT app to export the data as follows: • CSV file, for measurement blocks, e.g., for import to MS Excel. Date and time of measurement block creation and measurement capture, single readings, tolerance specification limits, if in the selected application set, are always exported.
Data transfer 8.2 Transfer single readings online to an Excel file via PC-Datex The data is transferred directly from the gage to the computer via an USB cable connection. For further processing of the data transferred from the gage commercially as well as internally developed data processing programs can be used.

Glossary 9 Glossary Amplitude sensitive eddy current test method Method for measuring the thickness of electrically nonconducting coating materials on nonmagnetic metals, DIN EN ISO 2360, ASTM D7091 Batch A file for organizing and controlling the measurement data. All the settings relevant to measuring the coating thickness of a coated sample and the measurement readings themselves are saved in a file. Such a file is called a batch in the gage. In the batch, you define the measurement procedure, e.g.
Material needed: Base material = FE = Ferromagnetic reference part from customer's own production, without the coating to be measured. • Gage types FE + NF: (display screen NC/NF) use of the amplitude-sensitive eddy current test method Material needed: Base material = NF = Non-magnetic, electrically conducting reference part from customer's own production, without the coating to be measured Calibration step Foil: Measurement on the calibration foil lying directly on the uncoated reference part.
Glossary Measuring application A measuring application is characterized not only by the material properties and the geometric shape of the Sample, but also by the measuring settings, e.g. limit monitoring and measurement reading grouping. If any one of these parameters changes, there is a new measuring application and you have to create a new Batch with appropriate Calibration.
