1 INTRODUCTION
You have purchased the compact TESA Rugo-
surf 20 and we thank you for your choice. To
help you to get the best performances from your
surface roughness gauge and to use it satisfac-
torily, we would advise to first read this manual
carefully.
To achieve reliable measurement results over a
long period of time, we would also recommend
to take all the precautions stated hereafter.
Your roughness gauge uses a cali-
brated stylus mounted at the probe
end. It is, therefore, advisable to
handle this unit with special care in
order to avoid shocks.
To keep it perfectly clean, use compressed air
under a pressure contained within 2 bars.
2 SAFETY PRECAUTIONS
– Make sure the indicated voltage matches that
of your mains supply.
– Do not attempt to dismantle the unit, except
for the parts listed in this manual. If you fail to
take this precaution, you might damage your
roughness gauge or cause a failure to occur.
– Do not subject the probe to stresses or
shocks. This sensitive component must be
handled with care.
– Do not use your roughness gauge in a dusty
environment, or have it exposed to vibrations.
Keep it away from appliances emitting noise
on the mains, such as air conditioners, trans-
formers or high-voltage relays.
– Do not use the gauge unit in places where
there may be excessive and sudden tempera-
ture variations. Do not leave it in a closed,
overheated room or exposed to direct sun-
light.
– Store your roughness gauge where tempera-
ture remains within -10°C to +50°C.
– Before you start measuring, remove any oil
spots or dust particles on the surface to be
inspected.
– Do not drop your roughness gauge. Avoid
shocks. Although solidly built, the measuring
system inside the unit may be damaged, thus
leading to incorrect measurement results.
