Q: Are multimeters now far more common due to their cost and precision? ¶
A: Yes, but analog multimeters are still preferable in some cases, for example when monitoring a rapidly varying value.
Q: Are multimeters often digital due to their accuracy? ¶
A: Yes, and durability and extra features.
Q: Are multimeters called VTVMs? ¶
A: Yes, and TVMs , FET-VOMs, and similar names.
Q: Is a multimeter to set the meter to measure resistance or current? ¶
A: Yes, and then connect it directly to a low-impedance voltage source.
Q: Was a multimeter developed by Frank Bishop of Intron Electronics in 1977? ¶
A: Yes, and which at the time presented a major breakthrough for servicing and fault finding in the field.
Q: Are multimeters available in a wide range of features and prices? ¶
Q: Is a multimeter often specified in the number of decimal digits resolved and displayed? ¶
Q: Is a multimeter the smallest part of the scale which can be shown? ¶
A: Yes, and which is scale dependent.
Q: Is a multimeter practically always a moving-coil galvanometer of the d'Arsonval type? ¶
A: Yes, and using either jeweled pivots or taut bands to support the moving coil.
Q: Are multimeters available with specified accuracy of better than ±0.01%? ¶
A: Yes, Laboratory grade instruments can have accuracies of a few parts per million.
Q: Were multimeters invented in the early 1920s as radio receivers and other vacuum tube electronic devices became more common? ¶
Q: Is a multimeter typically less susceptible to radio frequency interference? ¶
A: Yes, and so continue to have a prominent place in some fields even in a world of more accurate and flexible electronic multimeters.
Q: Is a multimeter given in units of ohms per volt? ¶
Q: Was a multimeter manufactured in 1955 by Non Linear Systems? ¶
Q: Are multimeters specified to have an accuracy of typically ±0.5% on the DC voltage ranges? ¶
Q: Is a multimeter attributed to British Post Office engineer? ¶
A: Yes, and Donald Macadie, who became dissatisfied with the need to carry many separate instruments required for maintenance of telecommunications circuits.
Q: Is a multimeter a combination of a multirange DC voltmeter? ¶
A: Yes, and multirange AC voltmeter, multirange ammeter, and multirange ohmmeter.
Q: Are multimeters common? ¶
A: Yes, a quality analog instrument will cost about the same as a DMM.
