Fig. 1 Woenia Super Autodrome
Important elements of the Autodrome woenia percent.
A measure of A Use handles to objects, such as thickness measurement Length diameter external objects
Oral measurement B Used to measure internal diameter of the object.
C axis Used to measure the depth of the object.
D major scale. The same scale as scale rulers are called. 2 Unit: cm (Or millimeters) And in
Scale E woenia A scale that makes it read more details. Scale woenia can move back and forth on the main scale.
F button. The scale woenia Used for sliding scale woenia
Saku, G Attached to the woenia scale. Use lock scale woenia fixation with main scale Make woenia not move while the scale reading measurement values.
Least value count
Woenia Super Autodrome (Briefly known as woenia) There are several versions, but with a similar shape that differs is the resolution of the measurement that is derived from the woenia scale as follows:
Let's woenia one has the same number of channel scale server all the n interval Nien woenia reads the value of resolution 1/n. 1 Main scale box.
If the scale of the woenia woenia one is the number of spaces equal to. 20 Channel and 1 A major scale box.
1 Mm, so woenia is this reads. 1/20 X equals 1mm 0.05 Mm, this value is called a least count of woenia, which is the smallest or most advanced woenia measured.
Least value count are usually printed on the woenia scale. If woenia is not of the least count, users must seek prior to measurement.
Use woenia
Using woenia, we can use woenia measurement of an object in multiple formats: 2 That is,
Fig. 2 Use of woenia measurement objects
Measure the length of the bar object. Diameter of the cylinder Center Using A measure such as 2 A..
To measure the diameter of inner ring hollow cylinder Using the measured image: B 2 B..
The measure of the depth of the object. Use the format axis C 2 C..
In every measure must provide for a task or object, and woenia is still. Non-entity.
Measuring value recording
Fig. 3 Measuring value recording
Image 3 Use woenia to measure the size of the spoon Users need to find a least count of woenia As follows:
Woenia scale box is equal to. 10 Channel
Major scale 1 Marked as 1mm
Therefore least count is equal to value. 1/10 x 1 Mm 0.1 mm
The measure will consist. 2 Section is readable from the major scale and the reading from the scale woenia. Bring value to both its will is read.
Reading values on the scale. To see if any of the woenia scale to match the main scale locations. Save values read from the major scale in millimeters Without considering differences of mm. But I find the scale woenia By notice of issuance of the woenia scale matches any of the major scale strokes and then remove the least value of woenia to count multiplied by its reading from the scale woenia. Multiplies the values read from a scale at woenia or fraction of a millimetre masks.
From the image. 3 Stroke center of scale woenia the tick. 32 Mm on the major scale is slightly but not reached a. 33 Therefore, the value read from the major scale is the scale 32mm waeania will see that the tick. 4 Your virtual machine woenia corresponds to which tick tick on the main scale. Therefore, the value read from the woenia scale of fractions or millimeters. It is the. .01 mmx 4 Equals 0.4 mm, that is quite readable and woenia is 32.0 mm-0.4 mm equivalent. 32.4 mm
