A-2. SOP #15 Gage Calibration & Verification

1. All Gages are Calibrated once a year and have a Calibration Sticker

2. Verify Calipers and Micrometers w/ Certified Gage Blocks (field verification with Pin Gages)

3. Verify Pin Gages w/ (verified) Calipers or Micrometers

4. Any doubt – Kick it out(return for calibration)

B-1. Care and Maintenance

1. KEEP the Gage CLEAN• Solvents & Oils attract dirt

• Dirt can cause an inaccurate reading

• Water causes rust & shorts the electronics

2. “ZERO OUT” the Gage often

3. If the Gage is dropped?• Do not use – Must be re-calibrated

• Request a new gage

4. Store Gage in the proper case+

B-2. Specifications

Dimensions1. Of part

2. Of nonconformingcriteria 2

B-3. Techniques for Use

1. Determine the Unit of Measure

2. Gage should be perpendicular to the Part

Unit of Measure Displayed As

Inches 1 in. or 1”

Millimeter 1 mm

Microns 1 µm or 0.001 mm

Do not use this area.

Perpendicular

B-3. Techniques for Use, continued

3. Gage should be flush with the Part• Important: Too much pressure may damage the

device or the part.

4. Measurements should be Repeatable

Flush = NO

C-3. Proper use of Gage Blocks

C-3. Proper use of Gage BlocksGage Verification

• To ensure equipment is working properly.

IMPORTANT:If gloves are not used, the Gage Block must be wiped with a clean cloth after use.

Example – Caliper verified at1.0 in” with a 1.000” Gage Block

C-3. Proper use of Gage BlocksTypes of Measurements

• Creating Go/No Go Gages for a precise measurement.

Example – Gage set at 1.05” with two Gage Blocks equaling the

measurement.

Gage Blocks Blocks are Stationary

C-4. Proper use of Pin Gages

C-4. Proper use of Pin GagesTypes of Measurements

1. Go/No Go Gages

2. Hole sizes

3. Gap sizes

4. Gage Verification(while at a project location)*

* Pin Gages are

Not Calibrated
