4 Measurement procedure
4.1 The power key 3-3 has to be pressed to switch on the instrument. `0` appears on
the display 3-2.
Both instruments, TF and TG, will recognize the mode of the last measurement itself
by the symbol appearing in the display `Fe` (= F) for ferrous metals or `NFe` (= N) for
non-ferrous metals. The instrument changes into the automatic measurement mode,
which also is able to recognize and assign also the zeroing plate or any other base
material.
4.2 The sensor 3-1 has to be placed onto a coating layer to be measured. The read-
ing on the display is the thickness of the coating layer. This can be corrected by
pressing the Plus- key 3-4 or the Minus- key 3-5. For doing this, the sensor should be
kept away from the measured object or the base plate for at least 5 cm.
4.3 To perform the next measurement, the sensor 3-1 has to be lifted for more than
1cm, “0” will be displayed and step b) has to be repeated. The instrument memorizes
the continuous measured value automatically with statistic measurement times.
Meanwhile, the Max, Min and average value will be displayed.
4.4 To avoid any appearing incorrect measurement values, we recommend adjusting
the instrument before starting with the measurements, as described in chapter 9.
4.5 To change the measurement unit from „µm“ to “mil” or vice verse, the Power-key
3-3 has to be pressed and not released until “UNIT” is shown on the display. Then
the same key 3-3 (this time Zero-key) has to be pressed.
4.6 To change the measuring mode from `single` to `continuous` or vice verse, the
Power-key / Zero –key 3-3 has to be pressed and not released until `SC` appears on
the display. Then the Zero- key 3-3 (the same one) has to be pressed.
The symbol “STATS” represents the continuous mode and `S` represents the single
mode.
5 Statistics
This instrument calculates and displays a statistical analysis of readings while the
measurements are taken.
The statistics available are:
•
Last value
•
Average value, marked by AVE
•
Highest reading marked by Max
•
Lowest reading marked by Min
•
Number of measurements taken
