When is the probe ground clip required to be connected when taking oscilloscope measurements?

Hi,
It's generally required at all times, but there is a problem though with most o'scopes, and that is that the o'scope's ground connection is also connected to AC ground through the AC power plug.
The best way to circumvent the possible shorting of the circuit you're testing, you should use an AC isolation transformer on the o'scope. This removes the AC ground from the scope but allows you to retain the signal and AC ground on the device being tested.
Hope this helps,

What precautionary steps have to be taken when using an oscilloscope?
Beware using ground clips for high speed measurements.Beware of oscilloscope bandwidth limitations.Ensure the correct triggering.Use the right oscilloscope probe.Remember to calibrate the oscilloscope probe.Beware using ground clips for high speed measurements.Beware of oscilloscope bandwidth limitations.Ensure the correct triggering.Use the right oscilloscope probe.Remember to calibrate the oscilloscope probe.
Can you wire a external and an internal ground together on a drier?
The ground wire should go from the dryer directly back to the distribution panel. An external ground wire is not required. The ground wire that is in the cord set that is connected to the frame of the dryer and the ground wire that is in the feeders coming from the distribution panel, that is connected to the ground terminal in the dryer receptacle, is all that is required to satisfy the code requirement.

What is ground coupling used for on an oscilloscope?
Ground coupling is a handy way to find the ground or zero volt level. Switching between ground coupling and DC coupling can be used to relate your DC coupled signal to ground. With modern digital oscilloscopes, the nominal ground level is typically displayed on screen. However, older analog scopes don't usually have this feature, so ground coupling becomes necessary. For more information please see the Tektronix oscilloscope app note "XYZs of Oscilloscopes". Available free from Tek's website.
How do you know if your ground wire is connected?
Measure the ground resistance from the user end point, where earth or ground cable is connected. It will show a very high resistance or open if ground is broken.
Does the ground wire on a 200 amp panel need to be looped through both ground rods?
Not looped but connected to both ground rods and then connected to the meter base.
What to do with no ground in wall but ground wire in fixture?
Very often the ground wire in the fixture is ignored, or just connected to the box, if there isn't a conductor to connect to. This, however, is a code violation as any fixture with a ground wire is required to have it properly connected to an equipment grounding conductor back to the panel. This is for YOUR SAFETY. Technically you should rewire the circuit with the proper conductors. It is BAD PRACTICE to connect the ground wire to the neutral or white wire because this could create a hazard of its own.

Does the ground run from the battery to the alternator?
Generally the battery ground lead is connected to the engine block and the alternator is bolted to the same block via metal brackets and thus connected electrically to the battery ground.
