DESCRIPTION
The Rotur external calipers are ideal for measuring outside dimensions during turning operations. With a threaded adjuster and a robust retaining spring, you can effortlessly make precise adjustments. The '4' corresponds to model C0524.
Using your Rotur 4 - inch external caliper is easy. First, open the caliper wider than the object you want to measure. Then, gently place the caliper around the object. Use the threaded adjuster to make fine - tuning adjustments until the caliper fits snugly against the object. Read the measurement on the scale. When using, avoid dropping the caliper as it could damage the precision parts. After use, clean the caliper with a soft, dry cloth to remove any debris. Store it in a dry place to prevent rusting. If you notice any issues with the adjuster or the spring, it's best to have it checked by a professional.
