Measure the distance between each set of marks. If the difference between the mea-
surements is less than 4mm (0.16 inch or approximately 5/32 inch), cone error adjust-
ment is not required.
Storage Precautions
Always clean the instrument after use.
Use a clean cloth, moistened with a neutral detergent or water. Never use an abrasive
cleaner, ether, thinner benzene, or other solvents.
Always make sure instrument is completely dry before storing. Dry any moisture with a
soft, clean cloth.
Note:
If difference exceeds 4mm (0.16 inch), contact your Topcon dealer.
EXAMPLE:
A1 – A2 = 10mm
B2 – B1 = 12mm
12mm – 10mm = 2mm
2mm is less than 4mm so cone error
adjustment is not required.
