Thats reason enough for us to give this WEN the heave-ho from our list. Determining the result should also be based on these standards. Its expensive and offers decimal readouts only, and it lacks a data port for transferring measurements to a computer. Calibrating a caliper means to assure that the caliper will still satisfy the Maximum Permissible Error (MPE). Fortunately, most of the features that contribute to the accuracy level of a pair of digital calipers also make them easier to use, such as polished stainless steel parts and a large, textured thumbwheel. Check if it was due to the battery, if theres a major problem with the LCD, it needs to be sent to repair services. By James Fitzgerald and Tom Scalisi | Updated Mar 31, 2022 9:53 AM.
