insert the batteries, connect the probe and turn on the instrument
zAdjust the instrument and probe to the base material to be measured
(7 ‘Adjusting Instrument and Probe’, beginning on Page 11) Normaliza-

zAlways hold the probe at its grip sleeve (right figure).
zAlways place the probe gently and at a right angle on
the specimen surface.
zSlide the grip sleeve to the specimen surface such that
the sleeve rests on the specimen (center and bottom
Figure, right).
zWith the default setting, a beep will signal the mea-
surement capture.
zLift 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.

6.2 Probe connection
A measurement probe must beconnected to the instrument to make coating thick-
ness measurements. This must be an appropriate probe suitable for the base ma-
terial.
Fig. 6-2 Connecting a probe
Connect probes only when the instrument is off!
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 visi-
ble.
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.

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).
7.1 Assigning a New Probe

Measuring
7.4 Reference Measurements
zPerform 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-
dard should be close to the nominal thickness value of the coating to be mea-
sured.
zIf 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.
zIf the mean value is not within the guaranteed error limits, perform a correc-
tive calibration, or repeat the corrective calibration, respectively.
8 Measuring
To make a measurement, place the probe at a right angle on thespecimen surface.
The probe can be lifted off after the measurement acquisition, i.e., after the read-
ing appears on the LCD display. The instrument is again ready to make measure-
ments.
Observe the following during the measurement:
zMeasurements should be made within the reference area.
zTo avoid erroneous readings, do not allow the probe to hover above the spec-
imen.
zHow 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.
zTo allow sufficient time for a measurement acquisition, the time between
individual measurements must be greater than 0.5 seconds.
The information stated in the operators's manual must be
observed when making measurements!
