| Keysight | U1270 Series Handheld Digital Multimeters - Data Sheet Key Functions Water and dust resistance (IP54) The series’ tightly sealed design helps protect against water, dust and damage. Each handheld DMM is certified with IP 54 ratings so that you can carry out tests and measurements with confidence, even in harsh working conditions.
| Keysight | U1270 Series Handheld Digital Multimeters - Data Sheet Key Functions Low impedance mode Peak detect at 250 µs 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.
