52. An ammeter is connected in series with the load to permit the load to limit current flow.
53. An ammeter shunt is a low-resistance device used to conduct most circuit current away from the meter movement.
54. A multirange ammeter operates on more than one range by connecting the meter movement to different shunts.
55. When an Ayrton shunt is used, the resistors are connected in parallel with the meter on some ranges and in series for other ranges.
56. When using clamp-on ammeter, the meter is only connected to one of the lines.
57. Resistance is measured with an ohmmeter.
58. The most common type of ohmmeter is the series type. On an analog series ohmmeter scale, zero is on the right.
59. An ohmmeter must NEVER be connected to a circuit when the circuit power is turned on.
60. The loading effect occurs when the connection of a meter to the circuit changes the entire circuit operation.
