U1271A Datasheet, PDF (4/22 Pages) List of Unclassifed Manufacturers – U1270 Series Handheld Digital Multimeters

Key Functions
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.
Figure 2. U1272A helps you identify the presence of stray voltage on a disconnected wire running parallel with the wire
powering up the VFD to an industrial motor. The image on the right shows the U1272A in low impedance mode.
