then pressing Zero key . It is about 7 seconds from starting depressing
Power key.
To change measurement mode from the single to continuous or vice visa,
just depressing the Power key and not releasing it till 'SC' on the Display
and then pressing Zero key. The symbol '↔ ' represents the continuous
mode and without '↔' represents single mode. It is about 9 seconds
from starting depressing Power key.
CALIBRATION
Zero adjustment
Zero calibration for 'Fe' and 'NFe' should be carried out separately. Take
the iron substrate if 'Fe' on the Display and take the aluminium substrate
if 'NFe' on the Display. Place the probe on the substrate steadily. Press the
zero key 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.
Select an appropriate calibration foil according to your measurement range.
Place the standard foil selected onto the substrate or the uncoated standard.
Place the sensor mildly onto the standard foil and lift. The reading on the
display is the value measured. The displayed reading can be corrected by
pressing the plus key or minus key while the probe is away from the
substrate or the measured body.
Repeat step 5.4 until the result is correct.
BATTERY REPLACEMENT
When it is necessary to replace the battery, the battery symbol will appear
on the Display.
Slide the Battery Cover away from the instrument and remove the batteries.
Install the batteries (4x1.5v AA/UM-4)
correctly into the case.
If the instrument is not to be used for any extended period , remove
batteries.
CONSIDERATIONS
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.
Probes 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.
