0.25-7″ PI Tape | Outside Diameter, Stainless Steel
Description
The PI tape [PN: T-03-937] is made of 716 stainless steel. It measures the OUTSIDE DIAMETER, and has a range of 0.75″ to 7″.
Features
- Gage Member: 0.25″
- Offset: 0.5″
- Material: 716 Stainless Steel
- Thickness: .006″
- Tolerance: ± .001”
Instructions
- Make certain the tape and object to be measured are both clean.
- Each line on the gage member represents 0.025″ of diameter, while each line on the vernier represents 0.001″.
- Wrap the tape around the object to be measured. The vernier scale should be just below the gage member. Tighten the tape around the object with 5 pounds of tension for O.D. tapes.
- Locate the “zero” on the vernier scale and note the highest value achieved on the gage member above it (the highest value to the left of the zero).
- Next, observe the vernier scale’s value at the point where it lines up exactly with a marked division line on the gage member.
- Finally, to obtain the diameter of the object, simply add the two values together.
- When using a standard O.D. tape on an I.D. surface, add the double the tape thickness to the reading to arrive at the I.D. of the part. It is suggested that direct I.D. tapes be used for inside diameter readings.
- As a suggestion for checking very large diameters – pieces of masking tape can be used to hold the tape in the proper parallel position.
- Tape resolution is 0.001″.
Care
- Tape is delicate. Handle with care. Keep tape clean and dry.
- After each use, wipe clean and apply a light rust preventative oil. Store in tape container and in a low moisture environment. Do not oil or use solvents to clean this product.
- Spring steel must be stored in a low moisture environment to prevent rust. No periodic adjustments are needed.
- Make sure the tape has not been stepped on or kinked, which may destroy the tape tolerance.
