 |
|
| I have recently bought a cheap relay tester. I found that it tested a straight forward 4 pin relay O.K. but all my 5 pin relays with a diode in them show as faulty. They are all working O.K. so perhaps the tester is faulty...or perhaps it is being foiled by the diode factor? |

A relay tester? what does it do that can't be done with a simple multi-meter?
I presume it must allow you to put different loads across the contacts to check for volt drop ? |
