3 First Steps
3.2 Operating and Maintenance Requirements
Ambient
conditions
The PDV can be used in dry areas under normal climatic conditions (refer to
CHAPTER
3.5). Avoid condensation on the optical components caused by a
rapid change in temperature. Avoid exposure to direct sunlight to prevent the
instrument from overheating.
Mains
connection
To avoid the danger of an electrical shock or faults, only use the plug-in power
supply PDV-AC provided by the manufacturer. Do not expose the plug-in
power supply to rain or moisture.
Assembly The PDV should not be provisional mounted but be mounted with help of
fixing screw threads on the mounting plate (optional) or stable tripod. To
ensure sufficient cooling, if possible mount the PDV on cooling metal
surfaces.
Cooling from
radiant
His essential to ensure unimpeded air circulation around the PDV and protect
it from radiant heat. With high ambient conditions, if possible mount it on
cooling metal surfaces to minimize heat built-up.
Connecting
cable
Make sure that all jacks are connected properly and firmly. Protect the
connecting cables against mechanical damage and high temperature.
Warming-up After switching on, the helium neon laser in the PDV will take a little while to
reach the optimal operating temperature after it has been switched on. The
PDV therefore reaches its optimal properties after a warm-up period of
approx. 20 minutes. After that you can be sure that all components are
working property in accordance with the specifications. Less accurate
measurements, such as to align the PDV for example, can however be carried
out with usefully results before this warm-up period has expired.
Cleaning The housing surfaces of the instrument can be cleaned with mild detergent or
disinfectant solutions. Organic solvents must not be used !
Optical
components
Handle all optical components with great care. Dirt may only be removed very
carefully with a soft, dry cloth, an optics brush and bellows.
Installation
of other
components
Hard or software components which do not belong to the vibrometer system
can damage the system. Using them will invalidate the warranty. If you want
to install such components please contact Polytec.
Opening the
instruments
It is not necessary to open the housings when using the equipment as
intended and will invalidate the warranty. Exchanging or retrospectively
installing modules may only be carried out by authorized service personnel of
Polytec.
Battery and
battery charger
(optional)
The lithium ion battery for the PDV can be used at temperatures of between
0°C to + 40°C (+ 32° F to + 104° F). Make sure, that there are temperatures
b 10°C to + 30°C (+ 50° F to + 86° F) when charging the battery.
