  • Page 15: Taking A Measurement

    4 TAKING A MEASUREMENT Before starting to take measurements it is good practice to check the performance of the gauge using the calibration adjustment procedure - see “Calibration adjustment” on page 16. 1. Hold the gauge with the probe pressed Integral firmly against...

  • Page 16: Calibration Adjustment

    5 CALIBRATION ADJUSTMENT The Elcometer 345 should be adjusted before use, or at least checked to ensure that the calibration adjustment is correct for the conditions of use. Calibration adjustment should be carried out with the appropriate probe, on the same type of metal, the same curvature and similar surface finish as that of the item to be measured.

  • Page 17: Calibration Adjustment For Smooth Surfaces

    5.2 CALIBRATION ADJUSTMENT FOR SMOOTH SURFACES Use this calibration adjustment procedure for measurements on smooth, flat surfaces. Note: The key-lock feature requires the keys used to access these routines to be pressed for 4 seconds before any response is made. This is to prevent accidental operation. 1.

  • Page 18: Special Calibration Adjustment

    6. Confirm that the gauge reads correctly at zero and at the calibration foil value. If required the calibration adjustment can be repeated to ensure its accuracy. To re-adjust the gauge, repeat all the steps in Section 5.2. Note: As well as calibration foils, certified coated standards are available - see “Spares and accessories” on page 32.

  • Page 19: The Correction Value Method

    4. Press and hold for more than 5 seconds to adjust this average to the foil value. 5. Press to accept the low calibration or wait 7 seconds to accept the calibration automatically. The display will now show CH1 (= Calibrate High). 6.

  • Page 20: To Recall The Factory Calibration

    The correction value is determined according to the roughness of the surface per ISO 8501, the Surface Roughness Comparator Elcometer 125. If the roughness of the surface under the coating is unknown a default correction value of 25 µm (1.0 mil) is subtracted from each reading. For further details see EN19840 'Paints and Varnishes - Corrosion protection of steel structures by protective paint systems - Measurement and acceptance criteria of the dry film thickness”.

    11 TECHNICAL SPECIFICATION Range: 0 µm to 1500 µm (0 mil to 60 mil) Accuracy: ± 3% of the reading or ± 2.5 µm (0.1 mil) whichever is the greater. ± 1% of the reading or ± 2.5 µm (0.1 mil) whichever is the greater when calibrated close to the thickness to be measured.
  • Page 29 Battery Life: 30 to 40 hours continuous with alkaline dry batteries (15 000 to 20 000 readings at an average of 8 readings per minute). Battery life is reduced when using the back light. Minimum Substrate Thickness: 300 µm (12 mil) unless special adjustment is made - see section 5.3. Gauges will have reduced range when adjusted for thin substrates.
