General Remarks on Measurement

After the calibrations have been made, all subsequent measurements will
lie within the guaranteed measuring tolerance. Strong magnetic fields near
generators or live rails with strong currents can affect the reading. When
using the Statistics Function for obtaining a mean value, it is advisable
to place the probe several times at a typical measuring spot. Any false
readings or outliers can be removed immediately via the Menu. The final
reading derives from the statistical calculation and from the guaranteed
tolerance levels of the gauge.

Coating Thickness D = X ± s ± u

Example:

Readings: 150um, 156um, 153um

Mean value: X = 153um

Standard deviation: s= ± 3um

Measuring uncertainty: u = ± (1% of r 1um)

D = 153 ± 3 ± (1.53um + 1um) = 153 ± 5.5um

Limit Function

Limits can be entered in Direct Mode and a selected Group memory at
any time. Any reading, which falls outside the set tolerance limits, will be
registered by a warning indication:

H: Reading above the HI limit

L: Reading below the LO limit

The limit values can be set by via the Menu. Press the Up or Down arrows
to scroll between the High or Low limits. Select the limits with the Blue
Bar Button, adjust the value with the Up and Down Buttons, and press the
Blue Bar Button again to confirm the limit.

Using Statistics

The meter calculates statistics from a maximum of 80 readings (GRO1 -
GRO4: a total maximum of 400 readings can be stored). In addition, read-
ings can’t be stored while in Direct Mode, but it can calculate statistics
as GRO1 - GRO4. When the meter is turned off or the Work Mode setting
has been changed, DIRECT statistics will be lost. The following Statistical
Values are calculated:
