Test Leads Unit UT-L20 by Unit — Measurement leads for multimeters, replacement cables

Measurement test leads Unit UT-L20 are replacement measurement cables designed for use with multimeters and other electrical testing instruments. They consist of flexible, insulated conductors with standard probe terminations that connect to common meter input sockets and allow secure contact with test points. The construction is intended for routine voltage, current and continuity checks in workshops, on-site service calls and general electrical troubleshooting.

Advantages

The Unit UT-L20 leads offer flexible insulation for ease of routing in confined spaces and reliable probe terminations compatible with most handheld multimeters. Their lightweight design supports extended use without adding significant bulk to a technician’s toolkit, while the insulation helps reduce the risk of accidental shorting during measurements. Materials and connectors focus on providing consistent electrical contact and repeatable readings.

Suitable for

• Measurement of DC and AC voltages with handheld multimeters
• Current measurements using multimeter current inputs and appropriate technique
• Continuity and diode testing in electronic and electrical maintenance
• Workshop diagnostics, field service and general troubleshooting tasks

When it may not be suitable

These leads are intended as general-purpose test leads and may not be suitable where specialty probes, extremely high voltages, or laboratory-grade low-noise measurements are required. For measurements that demand certified high-voltage insulation levels, specific safety ratings, or specialized form-factor probes (such as Kelvin/4-wire test leads), choose dedicated leads designed and rated for those applications.

Key specifications

• Lead type: flexible insulated test leads with probe terminations
• Typical use: voltage, current and continuity measurements
• Connector compatibility: standard multimeter input sockets (banana-style/probe-compatible)
• Insulation: flexible PVC or similar insulating material for routing and basic protection
• Colour: commonly supplied in standard meter colours for polarity identification

How to use

Connect the lead terminations to the corresponding multimeter input sockets (voltage/ohms and common) and verify secure seating before use. Observe correct polarity and use the appropriate meter function and range for the measurement. For current measurements, ensure the meter is set to the correct current input and range, and if required, move the probe to the meter’s dedicated current terminal. Avoid exposing the conductors or connectors to moisture or conductive debris and inspect insulation for damage before each use.

What to consider before purchase

• Confirm compatibility with your multimeter’s input connector types and current terminal layout
• Check whether you need leads with specific safety ratings or high-voltage certification for your applications
• Decide on required lead length and probe style for access to test points

Usage recommendations

Use the Unit UT-L20 leads for routine measurements with handheld multimeters, always observe meter and lead safety instructions, inspect leads for wear before use, and replace them if insulation or connectors are damaged.
