General warnings
•
It is dangerous to ignore the specified limits for the instrument or to use the instrument
when it is not in its normal condition. Use the applicable protection and obey all safety
precautions.
•
Do not use the instrument in locations with explosive gas, vapour or dust. There is a risk of
an explosion.
Pressure warnings
•
It is dangerous to attach an external source of pressure to a PV 62XG series pressure
station. Use only the internal mechanisms to set and control the pressure in the pressure
station.
•
Some liquid and gas mixtures are dangerous. This includes mixtures that occur because of
contamination. Make sure that the equipment is safe to use with the necessary media.
•
Pressurized gases and fluids are dangerous. Before you attach or disconnect pressure
equipment, safely release all the pressure.
•
To prevent a dangerous release of pressure, make sure that all the related pipes, hoses and
equipment have the correct pressure rating, are safe to use and are correctly attached.
•
For the PV 623G ensure that the system is bled of excess air before operation. (If the item
under test has a large volume, pre-fill with the pressure fluid to ensure that trapped air is
kept to a minimum).
Electrical warnings
If you use the DPI 620G calibrator with your pressure station, these warnings are also applicable:
•
To prevent electrical shocks or damage to the instrument, do not connect more than 30V
between the terminals, or between the terminals and the ground (earth).
•
This instrument uses a Lithium-Polymer (Li-Polymer) battery pack. To prevent an explosion
or fire, do not short circuit, do not disassemble, keep it safe from damage.
•
To prevent an explosion or fire, use only the Druck specified battery, power supply and
battery charger.
Cautions
•
To prevent damage to the PM 620 module, only use it within the specified pressure limit on
the label.
•
To prevent damage to the instrument, do not let dirt get into the pressure mechanism.
Clean the equipment before you attach it.
•
Before you start an operation or procedure in this publication, make sure that you have the
necessary skills (if necessary, with qualifications from an approved training
establishment). Follow good engineering practice at all times.
