1.4 Safety
1.4.1 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.
1.4.2 Instructions
The unit is designed to be used in complete safety if the instructions given in the accompany-
ing documents are followed. Any use apart from those defined, may prejudice the safety of
the operator and is therefore dangerous and forbidden.
1.4.3 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. Al-
so, 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.

General MC 75.2
- 18 - © SIKA •Ba_MC75.2_en •03/2017
Never exceed the limiting values of protection indicated in the specifications (§ 4).
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.
1.4.4 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 unfavourable conditions.
•The unit has been subjected to severe stress during transportation.
1.4.5 Definitions
