Line impedance, over-voltage, what does it have to do with over-current?
As the previous example illustrates, if you just measure over-current as related to the line impedance, you still have not measured the capacity for equipment damage. All you have done is checked that a bad network can appear safe under an artificially unique test condition. Typical over-current tests assume that the line voltage is correct and load impedance is ideal. Acceptable source impedances can mask over-voltage problems, and actual device loads can vary considerably. Potentially costly mistakes. Q: So over-current tests are invalid and all I need is a volt-meter, right? A: No, a volt-meter is still not enough and satisfactory over-current tests are not found in ordinary pocket testers. But the BT-10’s ability to dynamically measure a network can best warn you of a potential over-current condition. Also, a volt-meter is bulky and using one is too often cumbersome. You need the BT-10’s modular RJ11 flexible connector and convenient receptacle to simplify the task. Q: What about R
