Measuring equipment such as a Vernier caliper is often essential.

For example, when measuring the thickness of a plate a vernier caliper must be held at right angles to the piece.

It might seem that a vernier caliper cannot get out of calibration but a drop or knock can be enough.

In production environments, reading vernier calipers all day long is error-prone and is annoying to the workers.

For example, there were no micrometers available to Blanc, and although vernier calipers probably existed in his day, it is not certain if he used any.

He was plying a vernier caliper, and he added: "I'm certain of that second harmonic stuff now.

Vernier calipers commonly used in industry provide a precision to 0.01 mm (10 micrometres), or one thousandth of an inch.

Basic hand held instruments like Vernier Caliper, digital caliper, micrometer etc.

Micrometers are similar in use to vernier calipers but are more precise although the modern digital caliper has blurred the distinction between them.

The name comes from the analogy of rotating a spring-loaded vernier caliper around the outside of a convex polygon.

The concept is similar in use to vernier calipers which have a primary operation for gross (large) movement, and a secondary operation for fine movement.

The modern vernier caliper, reading to thousandths of an inch, was invented by American Joseph R. Brown in 1851.

Also existing colloquially but not in formal usage is referring to a vernier caliper as a "vernier" or a "pair of verniers".

However, vernier calipers require good eyesight or a magnifying glass to read and can be difficult to read from a distance or from awkward angles.

It was also endowed with many teaching and experimental instruments, such as desks, chairs, microscopes, vernier calipers, and multitesters from the Official Development Assistance Japan.

Vernier calipers are rugged and have long lasting accuracy, are coolant proof, are not affected by magnetic fields, and are largely shock proof.

Millwrights are trained to work with a wide array of precision tools, such as vernier calipers, micrometers, dial indicators, levels, gauge blocks, and optical and laser alignment tooling.

Positive zero error refers to the fact that when the jaws of the vernier caliper are just closed, the reading is a positive reading away from the actual reading of 0.00mm.

This would be a simple calibrated caliper; but the addition of a vernier scale allows more accurate interpolation, and is the universal practice; this is the vernier caliper.

Sometimes, the user doesn't care for removal of error from the instrument, else he compensates it in calculation, for example, the zero error in Vernier Caliper is eliminated by proper calculation.

Tammon was poring over a computed graph, measuring its various characteristics with vernier calipers, a filar microscope, and an integrating planimeter, when Mergon and Luloy came swinging hand in hand into his laboratory.

Shells were measured to the nearest 0.1 mm, using a vernier caliper, and the sample mean calculated for collections of 100 shells (later reduced to 50 and then 30 as it became apparent that increasing the number of measurements did not improve the accuracy of the mean)(Fig. 23).
