Description

Genuine Topdon · Part no. CT100A

The Topdon CT100 auto circuit tester measures DC voltage from 3.3 to 65V with 0.1V resolution and adds a load test (5-30V, 1.2A max) to show whether a circuit can carry current, not just voltage. It works on 12V, 24V and 36V systems, so cars, trucks and commercial vehicles, with polarity protection, dual-colour backlight, status lights, an extended lead and no batteries needed.

Good to know

  • Why the load test? A corroded wire or bad earth can show full voltage with nothing on, then drop when the circuit has to carry current; the load test draws current to show that.
  • Will it do lorries and buses? Yes, it covers 12V, 24V and 36V systems.
  • Does it need batteries? No, it runs from the circuit it is testing.

Which one?

For more functions see the Power Probe Circuit Tester PP3EZ with Learning Mode & Diagnostics Mode (PP3EZREDAS).
