What is a dwell meter?
A dwell meter measures the angle of rotation of the cam through which the points are opened and closed, and registers the dwell angle – the period when they are closed.
What is battery dwell?
The dwell time is the amount of time the ignition coil primary has current running through it.
What is the function of dwell angle?
Dwell angle is the amount of time, measured as degrees of rotation, that contact breakers close in a distributor. Unless dwell angle is accurate, ignition timing won’t be accurate. The period, measured in degree of cam rotation, during which the contact points remain closed is called the dwell angle.
How do you use a dwell meter for points?
Place a slot screwdriver in the adjustment slot on the points and have your assistant turn the engine over. Read the needle on the dwell meter. Turn the screwdriver clockwise to increase the dwell, or counterclockwise to decrease the dwell.
What is dwell time?

How do you test a Dwell meter?
Checking the Dwell Angle
- Turn the engine on.
- Take the reading on the tach dwell meter and compare it with the figure on the engine tune-up decal in the engine bay or in the vehicle’s service manual.
- Turn the Allen wrench slowly to adjust the dwell angle to the correct setting.
- Turn the engine off.
What is dwell controlled by?
Piston dwell period is controlled by the relationship of the crankshaft stroke to the connecting rod length. There are two schools of thought about piston dwell time read in crankshaft rotational degrees past top dead center (TDC).
What is period of dwell?
dwell time (usually uncountable, plural dwell times) The length of time that a thing or person remains in a given state. (chiefly engineering) The period of time that a system or element of a system remains in a given state.

- Attach the red lead on your meter to the negative “-” terminal on the ignition coil.
- Attach the black lead on your meter to any good ground on the engine; that is, an unpainted metal part.
- Set the meter for the number of cylinders your engine has.

What is the dwell angle of a 6 cylinder engine?
60°
The Dwell angle is 180° on a 360° (1 cylinder) meter scale and will read as 45⁰ on a 90° (4 cylinder) meter scale, or 30° on a 60° (6 cylinder) meter scale.
What is dwell time in chromatography?
Dwell time is the time spent acquiring the targeted MRM transition during each cycle. While very short dwell times can be used (5-10 ms) for extended compound screening, higher dwell times are desirable for better Signal-to-Noise (S/N).
