1 Safety and operational considerations
1.1 Warnings
•This document is a supplement to the Instruction manual!
•Before using EurotestEASI instrument read the Instruction manual carefully,
otherwise use of the instrument may be dangerous for the operator, for the
instrument or for equipment under test!
•symbol on the instrument means »Read the Instruction manual with special
care«. The symbol requires an action!
•If the test equipment is used in a manner not specified in Instruction manual
the protection provided by the equipment may be impaired!
•Do not use the instrument and accessories if any damage is noticed!
•In case a fuse has blown follow the instructions in Instruction manual to
replace it!
•Consider all generally known precautions in order to avoid risk of electric
shock while dealing with hazardous voltages!
•Do not use the instrument in supply systems with voltages higher than 550 V!
•Service intervention or adjustment procedure is allowed to be carried out only
by a competent authorized person!
•Use only standard or optional test accessories supplied by your distributor!
•Consider that older and some of new optional test accessories compatible with
this instrument meet only overvoltage category CAT III / 300 V! It means that
maximal allowed voltage between test terminals and ground is 300 V!
•Instrument contains rechargeable Ni-Cd or Ni-MH battery cells. The cells
should only be replaced with the same type as defined on the battery
placement label or in Instruction manual. Do not use standard alkaline battery
cells while power supply adapter is connected, otherwise they may explode!
•Hazardous voltages exist inside the instrument. Disconnect all test leads,
remove the power supply cable and switch off the instrument before removing
battery compartment cover.
•All normal safety precautions have to be taken in order to avoid risk of electric
shock when working on electrical installations!

1.2 Battery handling
•When battery cells have to be replaced or before opening battery/fuse
compartment cover, disconnect any measuring accessory connected to the
instrument and power off the instrument, hazardous voltage inside!
•Insert cells correctly, otherwise the instrument will not operate and the battery could
be discharged.
•If the instrument is not used for a long period of time remove the battery from its
compartment.
•Alkaline or rechargeable Ni-Cd or Ni-MH battery cells (size AA) can be used. The
operating hours are given for cells with a nominal capacity of 2100 mAh.
•Do not recharge alkaline battery cells!
The battery is charged whenever the power supply adapter is connected to the instrument.
In-built protection circuits control the charging procedure and assure maximal battery
lifetime. Power supply socket polarity is shown in the figure below.

Note:
•Use only power supply adapter delivered from manufacturer or distributor of the test
equipment to avoid possible fire or electric shock!

4.1 Replacing fuses
•F1
M 0.315 A / 250 V, 20×5 mm
This fuse protects internal circuitry of low-value resistance function if test probes are
connected to the mains supply voltage by mistake.
•F2, F3
F 4 A / 500 V, 32×6.3 mm
General input protection fuses of test terminals L/L1 and N/L2.
Warnings:
•Disconnect any measuring accessory and power off the instrument before
opening battery/fuse compartment cover, hazardous voltage inside!
•Replace blown fuse with original type only, otherwise the instrument may be
damaged and/or operator’s safety impaired!
