Special Features of this Continuity Tester:
- Loud enough to hear it easily.
- Turns itself off after a reasonable time (approximately two minutes), but you can extend the time each time it beeps.
- Has ‘instant’ response.
- Has very low probe voltage (~200 mV).
- Defines continuity somewhere in the 25 ohm range.
- No programmable parts.
- All through hole parts (well, almost all).
Kit includes all that is needed to build and start testing.
