I brought 3 new sets of brander digital caliper (150mm). When I use a
25 mm +/- 0 um 20 C length of micrometer standed bar for my verification on the caliper, the 3 sets of caliper give me 3 different reading ; 24.99 mm, 25 mm, 25.01 mm. I conducted this testing in a room temp. 28 C at 70 humidity. Can any person let me know which set of caliper is reliable ? ThanksRegards
