8.Considerations
8.1
In order to weaken the influence of the measured material on the
accuracy of measurement, it is recommended that the calibrations should be done on
the uncoated material to be measured.
8.2
Probe will eventually wear. Probe life will depend on the number of
measurements taken and how abrasive the coating is. Replacement of a probe can
be fitted by qualified persons only.
9.Restore Factory Setting
9.1
When to restore?
It is recommended to restore factory setting in the one of following cases.
A.
The gauge does not measure any more.
B.
Because misoperation "+"key or "-"key causes the gauge not normally to
measure.
C.
Measurement accuracy is degraded caused by environmental conditions
changed greatly.
9.2
How to restore?
9.2.1
Press the "um/mil" key and the "POWER" key at the same time,
and then release the "POWER" key firstly, 2 seconds later release the "um/mil" key
9.2.2
When the "9999" appears on the display, press the "POWER" key,
the factory setting is restored.
10.Notes
It is strongly recommened that no changes should be made to the value of Ln.
Generally, the larger the value of Ln, the smaller the reading on a same thickness. A
little variation of value of Ln will cause a great change in reading at high end (e.g. at
515um). The rules to adjust the value of Ln are as follow:
A.
Reading at low end can be adjusted to the
exact value by the plus or minus key.
B.
To enlarge the Ln if readings at low end (e.g.at 50 um) is ok but reading at
high end (e.g.at 388um) is too large. On the contrary, to decrease the Ln if reading at
low end (e.g. at 51 um) is ok but reading at high end (e.g. at 388um) is too small.
C.
Repeat procedures from A to B till the readings on the every standard foil
are satifying the accuracy.
