Before you buy
Honest guidance — you may not need this at all
- • If you already own a working multimeter or tester, a second one adds little.
Always verify the tester on a known-live outlet first, then on your target. It confirms the tester itself is working.
What it does
- • Audible and visual alerts
- • Auto power-off
- • Pocket clip
Maintenance tips
- • Test on a known live circuit before trusting a dead reading.
Frequently asked questions
Does it replace a multimeter?
No — it confirms presence of voltage, not exact values.
