❓ Frequently Asked Questions (FAQs)
Q1: What is the difference between Vernier and Digital Calipers?
Vernier calipers require manual reading; digital calipers display measurements electronically.
Q2: How often should the caliper be calibrated?
Typically annually, based on usage and internal QC policy.
Q3: Can this caliper measure depth?
Yes, it includes a depth measurement rod.
Q4: Is stainless steel better than carbon steel?
Stainless steel provides better durability and corrosion resistance.
