ZERO CALIBRATION
Zero adjustment for 'Fe' and 'NFe' should be
carried
out separately. Take the iron substrate if
'Fe' on
Display, while take the aluminium
substrate if 'NFe'
on the Display. Place the probe
(3-1) on the substrate
steadily. Press the Zero
key (3-3) and '0' will be
on the Display
before lifting the probe.
If pressing
the ZERO
key but the probe is not placed on
the
substrate or an uncoated standard. The zero
calibration is invalid.

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 Probes will eventually wear. Probe life will
depend on the number of measurements taken and
how abrasive the coating is. Replacement
separate can be fitted by qualified persons only.
