Measurement Functions

“Dip” Events

3M™ Dynatel™ Advanced Modular System 965AMS

1.Fault: A resistance fault will show as a dip on screen. The lower the value of resistance, the lower the dip.

2.Short: A short (or zero-Ohm resistance fault) will show up as the lowest dip on the screen. You cannot see events past a short.

3.BridgeTap: A bridge tap will look like a small dip where the bridge tap begins. The end of the bridge tap looks like an upward event. The distance between the two events is the length of the bridge tap. The start of a bridge tap looks like a resistance fault. Use the ohms measurement function to measure the resistance on the pair. If there is no resistance, and you see a dip followed by a peak, you might suspect a bridge tap.
