afety warnings
Follow the safety and usage instructions to
•
ensure proper operation and good condition
of the device.
Proper operation is only guaranteed if the
•
measuring wires are intact. Do not use the
device if the wires appear to be defective. In
case of their being damaged, replace them
immediately.
Never ground yourself when measuring
•
electricity. Do not touch metal pipes or other
objects, parts which may be grounded. To
ensure proper insulation from the ground use
insulating dry clothes, rubber-sole shoes, floor
mats or other insulating material.
Always disconnect the power source from a
•
circuit before modifying it (soldering parts,
etc.). Even weak currents may be dangerous.
To protect yourself and the device never
•
exceed the maximum inward values.
