read all the notes preceded by the symbol
.
Strictly adhere to the following instructions before and during measurements:
Do not measure voltage or current in wet or dusty places;
Do not measure in presence of gas, explosive materials or combustibles;
Do not touch the circuit under test if no measurement is being taken;
Do not touch exposed metal parts, unused terminals, circuits and so on;
Do not effect any measurement in case of unusual conditions of the instrument such as

Do not use the External power supply adapter (code DMT-EXTPS) if you notice
deformation, or breakage in the case, in the wire or in the plugs;
Pay careful attention when measuring voltages exceeding 25V in particular places
(building yards, swimming pools, etc.) and 50V in ordinary places because of the risk of
electric shock;
Use only cables and accessories approved by Amprobe;
The following symbols are used in this manual:
