- Designed & manufactured in the UK
- Measure capacitance & ESR
- Capable of In-Circuit testing
- Polarity free connect any way round
- Protected against highly charged capacitors Traditionally ESR equivalent series resistance can be a tricky thing to measure which is a shame its a very useful diagnostic parameter. Measuring a capacitors ESR equivalent series resistance is a great indicator of capacitor condition. The Atlas ESR offers instant results just connect the probes & press the test button. You can even use the Atlas ESR in-circuit saving you the trouble of removing capacitors. When testing capacitors out-of-circuit the unit will also display the capacitance.
