Frequently Asked Questions - HC-W88 Vevor
How to change the battery of the Vevor HC-W88 digital caliper?
To change the battery, remove the battery cover at the back of the display using a small screwdriver. Remove the old battery and insert a new LR44 button cell respecting the polarity. Close the cover and check that the screen lights up.
Why doesn't the screen light up after a few months of use?
This is usually due to a discharged battery. Replace the LR44 battery. If the problem persists, check that the metal contacts are not oxidized. Clean them gently with an eraser or a dry cloth.
How to switch from measurement in millimeters to measurement in inches?
Use the mm/inch button to change the display unit. The selected unit appears on the screen (mm or inch). This function allows you to quickly switch between the two systems without loss of precision.
How to perform an internal measurement with this caliper?
Use the upper, smaller jaws for internal diameter measurements. Place the tips into the opening then tighten gently until contact. Note the displayed value. Remember to zero with the jaws closed before measuring.
How to reset the display to zero before a measurement?
The ZERO button sets a new reference point. Close the jaws or place at the origin point then press ZERO to clear the value. This is useful for comparative measurements.
How to clean the caliper after use?
Wipe the surfaces with a soft, dry cloth. For stubborn marks, use a slightly damp cloth then dry immediately. Never use solvents or acids that could damage the display or measuring surfaces.
What is the accuracy of this caliper?
The accuracy is ±0.02 mm for the range of 0 to 150 mm, which corresponds to the standard accuracy class for a mechanical and digital measuring instrument. The displayed resolution is 0.01 mm.
Can I measure depths with this device?
Yes, thanks to the depth rod located at the end of the ruler. Place the end of the rod at the bottom of the hole and the base of the caliper on the surface, then read the value. The depth rod is extendable and lockable.
What to do if the display shows unstable values?
Check that the battery is in good condition and that the contacts are clean. Also ensure that the caliper is clean and that the measuring faces are not damaged. Recalibrate if necessary by closing the jaws and pressing ZERO.
How to store the instrument to prevent rust?
Wipe it, then apply a thin layer of protective oil on the stainless steel surfaces. Store it in its box away from humidity and temperature variations. Avoid shocks and never leave the instrument with the jaws closed under tension.
