the specimen surface.

z Slide the grip sleeve to the specimen surface such that

the sleeve rests on the specimen (center and bottom
Figure, right).

z With the default setting, a beep will signal the mea-

surement capture.

z Lift the probe off the specimen before making the

next measurement.

Avoid hard impacts.
Do not allow the probe to hover directly above

the surface. Doing so will lead to erroneous
readings.

Do not bend the probe connector cable! Doing
so can lead to broken wires.

A measurement probe must be connected to the instrument to make coat ing thick­ness measurements. This must be an appropriate probe suitable for the base ma­terial.

Connect probes only when the instrument is off!

System Setup

To turn the instrument off: Press the ON/OFF key on the right side of the
control panel. The LCD display is not backlit and no characters are visi­ble.

Protect the instrument and accessories from electrostatic
charges!

Electrical discharges may damage internal components or
delete internal memories.

Such discharges may occur, for example, when connecting the probe to
the instrument. Thus, please ensure that the person connecting a probe
is properly grounded.
It is recommended to store the instrument with the connected probe.

7 Adjusting Instrument and Probe

The following options exist after the instrument is turned on:

1.

The instrument recognizes the connected probe. The measurement screen
appears on the LCD display. The display of the measurement method does

not flash. In this case, you can start immediately making measurements.

2.

If the instrument is turned on and a probe other than the one used last is
connected, the following display will appear: “W006 Probe changed”. The
probe must be assigned ( Chapter 7.1).

7.4 Reference Measurements

z Perform several reference measurements by measuring the thickness of a

calibration standard placed on the uncoated reference area in order to verify
a correct normalization or corrective calibration. The thickness of the stan-

Measuring

dard should be close to the nominal thickness value of the coating to be mea­sured.

z If the obtained mean value is within the guaranteed error limits stated on the

foil, delete the readings of the reference measurement before starting with
the measurements on your specimens.

z If the mean value is not within the guaranteed error limits, perform a correc-

tive calibration, or repeat the corrective calibration, respectively.

8 Measuring

The information stated in the operators's manual must be
observed when making measurements!

To make a measurement, place the probe at a right angle on the specimen surface.
The probe can be lifted off after the measurement acquisition, i.e., after the read­ing appears on the LCD display. The instrument is again ready to make measure­ments.

Observe the following during the measurement:

z Measurements should be made within the reference area.
z To avoid erroneous readings, do not allow the probe to hover above the spec-

imen.

z How high the probe should be lifted off depends on the measurement range

of the probe. To obtain a correct air value, the distance to the specimen
should be at least 3 to 4 times the max. measurable coating thickness.

z To allow sufficient time for a measurement acquisition, the time between

individual measurements must be greater than 0.5 seconds.
