A.5 Safety

A.5.1 Compliance with safety standards
The unit is built and tested in accordance with European standard EN 61010-1: safety rules for electronic measuring
equipment.
These user instructions contain information and warning notices which must be respected by the user for protection
against danger from electric currents, ensuring correct operation of the unit and protection against any false step that
could damage the unit or make it unsafe to use.
The unit may, when necessary, be subjected to temperatures of between -10°C and +55°C without prejudicing safety.
A.5.2 Instructions
The unit is designed to be used in complete safety if the instructions given in the accompanying documents are followed.
Any use apart from those defined, may prejudice the safety of the operator and is therefore dangerous and forbidden.
A.5.3 Making measurements
Measuring wires and leads must be in good condition and must be replaced if their insulation appears defective (insulation
cut, burned, etc.).
When the unit is connected to the measurement circuit, the terminals may be dangerous. Also, never place your hands
near a terminal, whether in use or not. This advice also applies to the battery charger sockets and the USB link connected
directly or indirectly to the terminals of the unit. Any work on these circuits must be carried out with the unit disconnected
from any other external circuit.
Never exceed the limiting values of protection indicated in the specifications. Refer to chapter D.
When the order of magnitude of the value to be measured is unknown, make sure that the starting measurement range is
the highest possible, or choose the automatic range selection mode.
Before changing the function, disconnect the wires for measuring the external circuit. When measuring current and/or
voltage, even if low, remember that the circuits may be live with respect to earth, at a voltage that is dangerous for the
operator.
Never carry out resistance measurements on a live circuit.
A.5.4 Unusual faults and stresses
Whenever it is believed that the protection has been damaged, switch off the unit and ensure that it is not used
prematurely.
The protection may have been damaged if, for example:
There is obvious damage to the unit.
The unit is no longer able to make accurate measurements.
The unit has been stored under unfavorable conditions.
The unit has been subjected to severe stress during transportation.
