¹ With multi-point calibration, relating to the supplied standards under laboratory conditions

² With zero calibration and if calibration was made close to the coating thickness to be expected

³ If the precision stand is used, not applicable for HD sensors

⁴ If the „quick“ filter has been selected, measuring rate mainly dependent on handling

⁵ According to DIN 55350 part 13

⁶ With multi-point calibration values better than the specified data can be obtained.

⁷ including coating

* HD stands for Heavy-Duty version
