High-Impedance voltage measurement
High Impedance means high electrical Impedance. This is used to denote the input
Impedance or output Impedance of electrical circuits and devices in particular. When
measuring in the circuit, this has only a minor impact on the performance of the circuit,
particularly in the case of sensitive electronic circuits or control circuits.
Low-Impedance voltage measurement ( .25 )
Lz§f mode allows you to measure AC/DC voltages with a low impedance in this mode,
the Meter lowers the internal resistance to prevent ‘phantom’ voltage readings. As a
result, the circuit is more heavily loaded than in the standard measuring mode.
/\ Attention
P When using Lz (low input impedance) measurement, the continuous measurement
time cannot exceed 1 minute.
» Do not use LoZ mode to measure the voltage in the circuit that may be damaged
due to the low impedance of this mode.
