Meter-Reading Quiz

Wax nostalgic about and learn from the history of early electronics. See articles from Popular Electronics, published October 1954 - April 1985. All copyrights are hereby acknowledged.

Here is the 46th quiz I have posted from 1960s and 1970s issues of Electronics World and Popular Electronics magazines. Most of were created by Robert P. Balin. I like to save them for Friday afternoons. Guys like me who cut our teeth on analog meters read these indications like a second language. Even novices usually do a good job on the meter needles, but reading a mechanical micrometer (#9) might be more of a challenge, especially if you have never used one before. The same goes for a dial caliper. Can you read the dials on a mechanical gas or electric meter, where some spin CW and others spin CCW?

Meter-Reading Quiz

By Robert P. Balin

Electronic technician's, hobbyists, and experimenters are constantly required to make measurements using test instruments with a variety of dial calibrations. For in addition to the voltmeter, ammeter, ohmmeter, wattmeter, vu meter, etc., there are other instruments which, though seldom used by the average hobbyist, are of equal importance to the technician or experimenter. The micrometer is one of these.

Before testing your skill at reading meters, note the following useful procedures:

(1) Locate the zero index.

(2) Examine the scale to determine if it is linear or not.

(3) Determine the value of each major division and its subdivisions.

(4) Try to be as accurate as possible when approximating position of pointer or index within a scale division.

Now, see how accurately you can read the following meter scales, to the nearest tenths or hundredths.

 

 

See answers below.

Quizzes from vintage electronics magazines such as Popular Electronics, Electronics-World, QST, Radio-Electronics, and Radio News were published over the years - some really simple and others not so simple. Robert P. Balin created most of the quizzes for Popular Electronics. This is a listing of all I have posted thus far.

Meter Quiz Answers

The meter pointer (or index) indication is determined partly by counting the number of divisions-which is exact - and partly by estimating. Therefore, you may come up with a slightly different reading than the answers given below:

1)  0.29 ma.

2)  1.65 megohms

3)  -8.4 db (38%)

4)  7.7 volts

5)  16.3 ohms

6)  13.0 μa.

7)  102 volts

8)  1.25

9)  6.984 mm. The smallest division on the sleeve (stationary part) of this metric micrometer is 0.5 mm.; therefore, the reading is 6.500 mm., plus the reading of the thimble (rotating part). The smallest division on the thimble is 0.01 mm., giving a reading of 0.484 mm. for a total of 6.984 mm.  

10)  76.7 Reading from the zero index mark on the vernier (stationary tab), the indication is between 76 and 77 on the dial. Observe that the seventh division mark on the vernier is the only mark that coincides precisely with a dial scale division mark. This indication adds 0.7, for a reading of 76.7.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a lady's voice announced "You've Got Mail" when a new message arrived...
