Digital Multimeter
A reliable digital multimeter for measuring DC/AC voltage, current, resistance, continuity, and capacitance. Critical for verifying that capacitors are discharged before touching power electronics internals.
- Measures voltage (AC/DC), current, resistance, continuity
- Auto-ranging for quick measurements
- Backlit display for working in tight spaces
- CAT III safety rated for mains-level work
When to use it
Before opening any power electronics (chargers, power supplies, inverters). Always verify capacitors are discharged to safe voltage levels before touching anything inside.
What it replaces
A basic continuity tester can check some things, but a multimeter gives you the full picture. Don't skip this for power electronics.
Frequently asked questions
Yes. Every tool listed on this site is one we actively use in Object Opened teardowns. We don't list tools we haven't personally tested.
No. Start with a precision screwdriver kit, a spudger, and opening picks. That covers most phone and small device teardowns. Add specialized tools as your projects demand them.
We link to wherever offers the best version of each tool. iFixit specializes in repair tools with excellent quality. Amazon is better for general-purpose items and wider availability.
It depends on the device. Phones and laptops are generally safe if you disconnect the battery first. Power electronics (chargers, power supplies) can retain dangerous voltage in capacitors — always discharge them before touching anything inside. Wear safety glasses when prying open enclosures.
