-Now take readings by placing the probe on the coating and raise it if
steady.
-It may be necessary to delete calibration, e.g. after entry of a faulty
calibration value: MENU->delete->delete group data (NOTE: It will delete
all data, limit data, one-point and two-point calibrations except for zero-
point calibration).
-This will reactivate the default basic calibration for use on even
surfaces.
NOTE
: The meter calculates the mean of 5 calibration readings furthest.
When full, the newest calibration value will replace the oldest calibration
value.
-Press blue-bar button to exit current calibration. Or else, after about
30 seconds, the calibration will become effective automatically.
- Press Zero button to make current calibration effective compulsively.
Even while a series of measurements is being taken, foil calibration can
be carried out often as necessary. The old calibration will be overwritten;
the Zero calibration remains in memory.
4-2-3.Two-point Calibration
-Suggest that gauge is in single work mode. If necessary switch to the
mode as MENU system. This method requires the use of two different
foils. The thicker one should be, if possible, 1.5 times as thick as the thin
one.
- For best results, the thickness to be expected should be somewhere
between the two calibration values.
-This method is especially suitable for taking measurements on rough
shot-blasted surfaces or for high-precision readings. It is advisable to
take a mean for several times. This considerably reduces the effect of
scattering which occurs during calibration of upper and lower values.
The calibration foils may be used in any order.
-Zero-point calibration according to section 4-2-1
-The first point calibration according to section 4-2-2
-Repeat the step 2.
