Automation Dr. Nix QNix 4200 - User Manual

Instruction Manual
QNix
®
4200/4500, Version 3.6/2.7
System Description
The QNix
®
4200 coating thickness gauge measures all non-magnetic
coatings such as lacquer, enamel, chromium, copper, zinc etc. on steel or
iron.
The QNix
®
4500 coating thickness gauge additionally measures all
insulating coatings such as lacquer, plastic, enamel, etc. on non-magnetic,
metal substrates, e.g. on aluminum, copper or brass.
Both gauges conform to national and international standards:
ISO 2178, 2360, 2808
ASTM B 499, D7091
General
This measuring gauge has been designed for various applications.
Despite its rugged design, it should be handled correctly to insure
correct measurements at all time.
Do not drop it. Protect it from dirt, dust, humidity, chemicals and
aggressive vapors.
Please store the gauge in the protective case after using it.
As with all precision instruments, large temperature variations can
inuence the measuring result. Please avoid direct solar irradiation and
temperature shocks.
Due to the physical measuring principles the measurements can be
inuenced by strong electromagnetic elds. Please stay away from
transformers, high voltage lines or discharge sources for example.
Do not take measurements on magnetized parts. Magnetic elds can affect
the Fe-measurements. Strong electromagnetic radiation can affect the
NFe-measurements.
The housing is resistant against most solvents. Use a soft damp cloth to
clean the housing.
Proper results can only be achieved with clean probes. Please check the
probe tip regularly and remove any dirt and paint from the ruby.
Cable Probe version
When using QNix® 4200 and QNix® 4500 with Cable Probe or trans-
porting it, take care not to bend the cable. In case the cable breaks due
to difcult measuring conditions or high strain on the cable you can re-
order it and easily replace it yourself.
If you use several QNix® 4200 and QNix® 4500 gauges with cable probe,
you can switch the probes between the gauges to guarantee highest exi-
bility during your daily measuring tasks.
