3. Mechanic Measuring Instrument
1. Ruler
Ascertains ruler to stay as near by possible with equiamplitude surface of substance measured. Read of measure scale at ruler must be vertical with plane surface measured

4. Mechanic Measuring Instrument
2. Rectangle Ruler
Usage of rectangle ruler is done by ascertaining is wrong one divisions becomes reference. Then pastes up powerfully boom at the reference plane, Gives attention to its the shavings side

5. Mechanic Measuring Instrument
3. Straightedge
Pastes up straightedge above the equiamplitude surface to know its the un-flatness or aberration

6. Mechanic Measuring Instrument
4. Meter Band
Way of using it is by hooking correlating nose from plane roll, then draws meter sufficiently below(under the meter length ( usually maximum length written at body meter)

7. Mechanic Measuring Instrument
5. Protractor
Protractor is applied by gluing the device at substance which will be measured. Determines one points as one of fiducial point

14. Mechanic Measuring Instrument
Way of using
Firstly, shift slide caliper according to its the requirement and breach-block screw key
Teknologi dan Rekayasa

15. Mechanic Measuring Instrument
Sees number zero at second caliper vernier scale, point searching where number at scale under vernier caliper as of line with number at metering rod scale and read result of his its.

8. Dial indicator
In its use, dial indicator cannot stand up x'self, causing requires buffer joint and block magnet

17. Mechanic Measuring Instrument
Way of reading dial indicator
Minute hand shows line to 6, result of its the read is 6 x 0,01 = 0,06 mm. Whereas hours hand refers line to 3, mean minute hand has rotated 3 times. Result of gauging of is 3 + 0,06 = 3,06 mm

10. Micrometer Usage
Enters micro meter at substance which will be measured
Rotary ratcher stopper until says “ clicks”. Locks ( lock clampI and disengaged of micro meter from work substance

19. Mechanic Measuring Instrument
Reads result of gauging Mikrometer
Distance every stripe to horizontal line at outer sleeve is 1 mm, and distance every stripe below under line is 0,5 mm. At scale thimble every its the value stripe 0,01 mm. Result of gauging at micrometer is number of third reads of the scale.

20. Mechanic Measuring Instrument
Reads result of gauging Mikrometer
Scale above line ,00 mm
Skala below under line 0,00 mm
Skala thimble 0,20
final mm ,20 mm

9. Dial bore indicator
9. Dial bore indicator
Cylindrical diameter measure with slide rule, for example obtained result of gauging : 75,40 mm.
SPACER
Replacement rod
DIAL GAUGE
Select and tide replacement rod which length bigger than result of gauging, for example 76 mm.
Teknologi dan Rekayasa

22. Mechanic Measuring Instrument
Length measure replacement rod with external micrometer and labours needle dial non movable gage, for example obtained result of gauging = 76,20 mm
Teknologi dan Rekayasa

23. Mechanic Measuring Instrument
Enters replacement rod into aperture ( platen), shakes down peduncle bore gage dextrorse and sinistrorse like at drawing 30 until obtained by the biggest aberration ( position of perpendicular)
Teknologi dan Rekayasa

24. Mechanic Measuring Instrument
Read level of aberration posed at dial gage, for example obtained by 0,13 mm. Level of platen diameter is difference between result of measurement of lengths replacement rod with level of aberration of needle bore gage.
So platen diameter = 76,20 – 0,13 = 76,07 mm.

11. Usage of torque key X 90
Teknologi dan Rekayasa

26. Mechanic Measuring Instrument
Torque moment is applied together with key shock put down at the end of his its. Enters shock key at nut or bolt which will be tightened, draws its the handle until needle shows number moment wanted or happened click noise to lock moment of click type
