System Description
The dry film thickness gauge
QuaNix
®
Keyless
is a combination gauge for
a large variety of applications. Optionally it can be supplied with memory
and statistic functions.
The
QuaNix
®
Keyless
consists of the basic gauge and a miniature probe
that can be taken out of the basic gauge. The gauge has two special fea-
tures. First no operating keys are required. Neither a calibration nor a zero
adjustment has to be performed by the user. The zero adjustment is auto-
matically done while the probe is taken out of the basic gauge. Second, the
readings taken by the miniature probe are transmitted wirelessly to the ba-
sic gauge. No troublesome and delicate cables impede the measurements.
When the basic gauge, inserted in the pouch, is fixed e.g. to an arm, one-
hand operation is possible even under difficult conditions, e.g. on scaffolds
or masts.
The Fe-probe measures all non-magnetic coatings such as lacquer, plastic,
enamel, powder coating, chromium, copper, zinc etc. on steel or iron.
The NFe-probe measures all insulating coatings such as lacquer, plastic,
enamel etc. on metallic substrates, e.g. on aluminum, copper, brass or non-
magnetic steel.
Via the RS232-interface, which is standard in all gauges, readings can be
transferred online to a PC or to our mini-printer
PT 7
.
In the gauge with memory the readings can be stored and divided into
blocks. Up to 4000 readings can be stored. For further processing, our
QuaNix
®
-software or the mini-printer
PT 7
is optionally available.
The
QuaNix
®
Keyless
conforms to national (DIN) and international
(ISO,BS, ASTM) standards:
DIN 50981, 50984 ISO 2178, 2360, 2808
BS 5411 (3,11), 3900 (C,5) ASTM B499, D1400
General
This instrument for a large variety of measuring tasks has been designed
with the latest electronics. Despite its precision it is handy and rugged.
However do not let it drop and protect it from dirt, dust, humidity, chemicals
and aggressive vapors. After use please insert it into the pouch supplied
with the instrument.
As with all precision instruments large temperature variations can influence
the measuring result. Please avoid direct solar irradiation and temperature
shocks.

Due to the physical measuring principles the measurements can be influ-
enced by strong electromagnetic fields. Please stay away from e.g. trans-
formers, high voltage lines or discharge sources. Strong emitters in the fre-
quency band used for the data transmission between miniature probe and
basic gauge can jam receiving in the basic gauge.
The housing is resistant against most solvents. Just use a soft damp cloth
to clean the housing.
Proper results can only be achieved with clean probes. Please regularly
check the probe tips and remove any dirt and paint from the rubies
If the gauge is not used for a longer period, please remove the batteries
from the basic gauge in order to prevent leakage that can damage the
gauge.
In case of a malfunction of the instrument please do not try to repair it on
your own. Our customer service will be happy to be of assistance.
Operating and Change of Batteries
The
QuaNix
®
Keyless
is powered by two 1,5 Volt AA batteries (Alkali). The
battery compartment is on the rear side of the gauge. The battery should be
exchanged when the "BAT"-sign appears on the right side of the display.
However quite a number of readings can still be taken before the gauge
shuts off. In gauges with memory stored data will not be deleted when
changing the battery.
The miniature probe is powered by an integrated Lithium battery which is
automatically charged when the probe is inserted in the basic gauge. When
the probe battery is getting weak the sign "Accu" appears in the display.
Also in this case several readings can still be taken. The probe battery
needs about 3 hours to be recharged.
Empty batteries should be disposed of properly. If possible, please use the
special services of your council.

Handling
To switch on the gauge the miniature probe must be taken out of the basic
gauge. To do so please turn the probe by 90 degrees and take it out of the
fixture. During this procedure both integrated probes are automatically ini-
tialized. Then measurements can be started immediately. The Fe-probe
with the blue ring is used to measure on steel or iron substrates; the NFe-
probe with the red ring is used for non-magnetic substrates such as alumi-
num, copper etc.
Place the probe evenly on the object to be measured such that the ring
around the probe is in full contact with the surface. The display of the read-
ing is accompanied by a beep. Simultaneously the display shows which
probe, Fe or NFe, has been used. The sign "Err" (error) indicates incorrect
placement of the probe or lift-off before the measurement is finished. The
sign "I
Π
FI" (infinite) indicates readings beyond the measuring range.
Insertion of the Probe:
The
red ring
of the miniature probe must be on the
left
side with the
red mark
of the basic gauge
.
Wrong insertion of the miniature probe will damage the gauge.
Special Applications:
In most cases the automatic zero adjustment of the two probes insures cor-
rect measuring results. In those few applications where an individual zero
adjustment is required please proceed as follows: Place the appropriate
probe on a piece of uncoated substrate. After a reading is displayed press
the probe which is not used for measuring. A control number is displayed
and a beep sounds. Lift off the miniature probe at least 5 cm (2"). Another
control number is displayed and a beep sounds again. Now the special zero
adjustment is done. Note: The special zero adjustment is replaced by the
standard zero when the miniature probe is inserted into the basic gauge
and taken out again.
Do not take measurements on magnetized parts
. Magnetic fields can af-
fect the Fe-measurements. Strong electromagnetic radiation can affect the
NFe-measurements

Online-Measurements
All
QuaNix
®
Keyless
gauges are equipped with an RS232-interface. This
allows the transfer of all readings directly to a PC or our mini-printer
PT 7
.
For the online display of the data on the PC monitor, the
QuaNix
®
-software
can be used to immediately provide a comprehensive statistical evaluation,
or standard-editing programs such as HyperTerminal found in Windows-
software works as well. The instrument must be connected with the PC or
the printer via the interface cable, and it must be switched on. The interface
socket is on the right side of the basic gauge. Each reading or each statisti-
cal value is immediately sent to the PC or is printed by the mini-printer.
Change of Unit µm/mil
The display of the readings by the
QuaNix
®
Keyless
is factory set to the
unit which is common for the user (generally µm). Changing the unit can be
performed with our optionally available
QuaNix
®
–software or with the mini
printer
PT 7
. Regarding the procedure, please see the instruction manual of
the
QuaNix
®
-software or the printer respectively.
