VOLTCRAFT VC-330 Bedienungsanleitung Seite 33

• Set the measuring device to the desired unit before each measurement. A false
measurement may destroy the product!
• The voltage between the connection points must not exceed the specified
voltage.
• The test prods must be removed from the measured object before changing the
measurement range.
• Be particularly careful when dealing with voltages >25 V/AC and >35 V/DC! At
these voltages you may receive a fatal electric shock when touching electrical
conductors.
• Inspect the measuring device and the test leads for damage before each
measurement. Never take measurements when the insulation or the product is
damaged.
• To prevent an electric shock, ensure that you do not touch the connections to be
measured / measuring points when measuring, either directly or indirectly.
• Do not touch the grip markings on the test prods and on the measuring device
when measuring.
• Avoid using the device in the immediate vicinity of:
- Strong magnetic or electromagnetic fields
- Transmitting antennas or HF generators.
• When taking measurements, ensure that no objects are trapped by the current
clamp sensor, such as cables.
• Always ensure that the polarity is correct when connecting the test leads to the
measuring device. (red = positive terminal, black = negative terminal).
• Pay attention to the diagrams in each chapter for every measurement. A false
measurement may destroy the product!
• Before connecting the test leads, remove the dust protection caps on the
connection sockets. Replace the caps after each measurement to prevent the
contacts from becoming dirty.
• Also pay attention to the safety information in the individual chapters.
