What is Transfer Measurement?
- An Instrument that is incapable of measurement is used to a establish and represent and unknown distance
- The unknown distance represented by the instrument is a transferred to an instrument that capable of showing measurement.
State all the Transfer Measuring Type. ( 3 of them)

- 6
- 12
- 18
- 24
What are all 3 types of Calipers?
- Spring Caliper
- Firm Joint Caliper
- Lock Joint Caliper
________ Caliper are used for very accurate work. ( Precisely using the adjustment nut )
Spring Caliper
______ Caliper has no fine adjusting nut.
Firm Joint Caliper
Using Caliper
A SENSE OF FEEL is a ability to transfer measurements between measurement tools consistently and without loss of accuracy.
_______ Gauge are used for measuring bores, slots and recesses and do not have a measuring scale.
Telescoping Gauge
Parts of Telescoping Gauge
- Plunger
* Locking Screw

What are the 2 types of Dial indicator holders? 
- Magnet Base
* attachment style
Two types of potential dial indicator errors.
- Spindle travel
* Cosine Error
_______ measurement is going to be always larger
Cosine Error
________ is used for checking bearing alignment or shaft deflection without dismantling the engine or compressor. 
Crankshaft Deflection Gauge
List the three measurements for which you primarily use telescoping gauge.
- Bores
- Slots
- Recesses
List the two dial reading styles.
- balanced
* continuous 
What is the advantage of dial bore gauge?
It can be moved in various position in the bore where different readings can be taken without making adjustment.
