1.2 BEFORE USE Always keep to the instructions contained in this manual: CAUTION Non compliance with the warnings and/or the instructions may damage the tester and/or its components or injure the operator. Before changing the switch’s position, take off the clamp jaw from the tested conductor or the electrical circuit in order to avoid any accident When the clamp is connected to the circuits to be tested, never touch unused terminals When testing resistors, do not add voltage. Although there is a protection circuit, excessive voltage would cause malfunctioning Before measur ...
