FAQs
Does this gauge include metric and imperial measurements?
This specific model (CT1190) is primarily calibrated for metric measurements ranging from 0.05mm to 1.0mm.
Can I use this for measuring spark plug gaps?
Yes, it is designed specifically for setting and checking spark plug gaps accurately.
What should I do if a blade gets bent?
If a blade is slightly bent, you can attempt to straighten it carefully with pliers, but for high-precision tasks, it is recommended to replace the tool to ensure accuracy.
How do I know which blade is which?
Each individual leaf in the Neilsen set is clearly stamped with its thickness measurement for easy identification.
Is this suitable for professional workshop use?
Yes, its robust construction makes it suitable for both professional mechanics and serious automotive hobbyists.
Troubleshooting
Blade feels stuck in the gap
Do not force the blade; use a thinner blade first to verify the gap size, then work up to the correct thickness.
Surface rust appearing on blades
Gently clean the blades with fine steel wool or a scouring pad, then coat with a thin layer of machine oil.

Setup, Compatibility & Care
Using the gauge requires no complex setup; simply unfold the blade that matches your required measurement. It is compatible with virtually all internal combustion engines requiring manual clearance adjustments. To ensure longevity: always wipe the leaves clean with a lint-free cloth after each use to remove oil and grime. Apply a very light coat of machine oil before storing to prevent oxidation, and always fold the leaves back into the protective casing to prevent warping or snapping.
