I. Safety Precautions And Procedures

For your own safety and to avoid damaging the instrument you are

recommended to follow the procedures described in this manual

and read carefully all instructions preceded by this symbol

Before and during measurements keep to the following

instructions:

● Do not take current measurements in wet places

● Do not take the measurements in the presence of explosive

gas and combustibles or in dusty places

● Avoid any contact with the circuit under test even though you

are not taking any measurement

● Avoid any contact with exposed metal parts, unused measuring

terminals, circuits etc. Do not take any measurement whenever

anomalous conditions occur such as deformations, breaks,

leakages, blind display etc

The herewith symbols are used in this manual and on the meter

CAUTION: refer to the instruction manual. An improper use

may damage the instrument or its components as well as endanger

the user.

High voltage danger: risk of electric shock
