What Is a Digital Vernier Caliper?

Digital vernier caliper is a length measuring tool that displays the measured value digitally. It is an instrument for measuring length, inside and outside diameter. Digital vernier caliper grating, capacitive measuring system and the like.

Digital vernier caliper common resolution is 0.01mm, tolerance of ± 0.03mm / 150mm. There are also high-precision digital calipers with a resolution of 0.005mm, and the allowable error is ± 0.015mm / 150mm. There are several multipurpose resolution was 0.001mm micrometer caliper, a tolerance of ± 0.005mm / 50mm. Digital vernier caliper high efficiency, clear visual readings.

Mainly for thickness measurement, leather, rubber, paper and various paper fabric sheet metal, plastic plate or the like.

The engraved surface is matte chrome, laser engraved or black chrome photoengraved.

Made of stainless steel or high-quality carbon steel.

It has four functions of measuring inner diameter, outer diameter, depth and step. .

When measuring the outer diameter, the two outer measuring surfaces should be attached to the measured surface.

When measuring the inner hole size, the measuring jaw should be measured in the diameter direction of the hole.

When measuring the depth, the depth ruler should be perpendicular to the bottom surface of the workpiece to be measured.

Before use, loosen the fastening screws on the ruler frame, pull the ruler frame smoothly, and wipe the measuring surface and guide surface with a cloth.

Check the "zero" position: Push the ruler frame slightly to merge the two measuring surfaces of the caliper claws. Observe that the "zero" engraving line of the cursor and the "zero" engraving line of the ruler should be aligned. Qi. Otherwise, it should be sent to the measurement room or relevant departments for adjustment.

After using the caliper with depth ruler, the measuring claw should be combined. Otherwise, the thinner depth ruler is easily deformed or even broken when exposed. After use, the caliper must be cleaned and oiled and put back in the caliper box (or bag). Do not place the caliper on a magnetic object. It is found that the caliper is magnetic and should be demagnetized before use.

When moving the ruler frame and the micro-movement device, loosen the fastening screws.

Do not use the caliper as a caliper or screwdriver or use the tip of a measuring claw as a scribing tool, compass, etc.
