1. SAFETY PRECAUTIONS AND PROCEDURES
The instrument is conforms with safety standards IEC/EN61557 and IEC/EN61010-1
relating to electronic measuring instruments.
CAUTION
For your own safety as well as that of the apparatus you are recommended to
follow the procedures described in this instruction manual and carefully read
all the notes preceded by the symbol
.
Strictly keep to the following instructions before and during measurements:
Do not take measurements in wet environments
Do not effect measurements in environments with explosive gas, fuels or dust
Keep you insulated from the object under test waiting for measuring
Avoid any contact with exposed metal parts, ends of test leads not in use, circuits, etc
Do not perform any measurement in case of unusual conditions of the instrument such
as deformation, breakage, leakage of substances, absence of display reading etc
Pay careful attention when measuring voltages exceeding 25V in particular places
(building yards, swimming pools, ..) and 50V in ordinary places because of the risk of
electric shock.
The following symbols are used in this manual:
