To calibrate the Sealey AK9623EV Vernier Caliper, ensure the caliper is clean and dry. Close the jaws completely and check the zero reading. If it's not zero, adjust the scale using the calibration dial. For precise calibration, use a calibrated gauge block.
Clean the caliper with a soft, lint-free cloth to remove dust and debris. Avoid using water or solvents. Regularly apply a light machine oil to the sliding surfaces to prevent rust. Store in a protective case when not in use.
To measure internal dimensions, use the smaller jaws located at the top of the caliper. Insert them into the object and expand until they touch the internal sides. Read the measurement on the scale.
Inaccurate measurements might be due to dirt on the scale, improper zero setting, or mechanical damage. Ensure the caliper is clean, recalibrate it, and inspect for any physical damage.
The Sealey AK9623EV Vernier Caliper does not have a direct switch for metric and imperial units as it is a manual caliper. You need to manually read the scale for the desired unit of measurement.
If the sliding movement is not smooth, clean the caliper's beam and apply a small amount of machine oil to the sliding surfaces. Check for any physical obstructions or damage.
To measure depth, extend the depth rod by sliding the main scale. Insert the rod into the hole or slot you wish to measure, ensuring the end of the caliper body rests on the surface. Read the measurement.
The maximum measuring range of the Sealey AK9623EV Vernier Caliper is 150mm or 6 inches.
Ensure the caliper is clean and free from debris, properly calibrated, and held perpendicular to the object being measured. Consistent pressure should be applied when taking measurements.
Yes, the Sealey AK9623EV can measure the outer diameter of round objects using its main jaws. For internal diameters, use the smaller jaws. Ensure the caliper is perpendicular to the object for accuracy.
