Low impedance mode

Stray voltages are usually found

in non-energized electrical wiring

adjacent to powered wires due to

capacitive or inductive coupling

between these wires. The low

impedance mode serves to eliminate

false readings by dissipating these

stray voltages thus improves safety

and measurement efficiency during

voltage measurement.

Peak detect at 250 µs

The peak detect function allows

you to capture the engine or motor

startup transient as fast as 250 µs.
