• Check the measuring device and its test leads for damage before each measure-
ment.
• Set the measuring device to the desired unit before each measurement. An incor-
rect measurement may destroy the product!
• The voltage between the connection points must not exceed the specified voltage.
• Always remove the probe tips from the measured object before changing the
measurement range.
• Take particular care when dealing with voltages exceeding 33 V AC or 42 V DC.
Even at these voltages, there is a danger of fatal electric shock if you touch electri-
cal conductors.
• To prevent an electric shock, do not touch the measurement points when taking
measurements, either directly or indirectly.
• When taking measurements, do not touch any area beyond the grip markings on
the probe tips and the measuring device.
• Avoid using the device in the immediate vicinity of:
- Strong magnetic or electromagnetic fields
- Transmitting aerials 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 section for every measurement. An incorrect
measurement may destroy the product.
• Before connecting the test leads, remove the dust protection caps from the con-
nection plugs. Replace the caps after each measurement to prevent the contacts
from becoming dirty.
• Observe the safety information in each section.
• Never use the measuring device without the covers on the back or the battery
compartment. There a risk of electric shock.
