LUOWEI LW-315 Gold-Plated Multimeter Test Leads

Standard multimeter probes are made for wall sockets and car batteries, not the tiny pads of a phone board. The LUOWEI LW-315 swaps in needle-sharp tips of about 0.2 mm so you can land on a single capacitor without bridging its neighbor.

The LW-315 is a universal multimeter test pen set from LUOWEI, rated up to 20A and 1000V. It has gold-plated stainless steel probes with replaceable tips, insulated silicone handles with an anti-slip grip and flexible silicone-insulated leads with a tinned copper core. The listing says it works with most digital multimeters.

When to upgrade to the LW-315

• Blunt or bent tips that slip off small components.

• Stiff leads that drag the probe off a test point.

• Cracked insulation on old leads.

• Frequent board-level work where precision matters more than reach.

Using fine tips well

Sharp tips can scratch through solder mask, so place them on pads and component ends rather than traces. Replace a tip as soon as it bends, since a bent needle slips at the worst moment.

Check that the plugs fit your meter's sockets before ordering, and remember that the meter, not the leads, sets the real safety limit.
