when the sliding piece is moved not veeeery slow. For this price I expect no tool that absolutely and 1/100 accurately measures, but the normal handling pushed together, on Zeroing and measuring, should already work. From the first Auseinderziehen I had a strange feeling that the distance the measuring surfaces and the display in the display lights. First thought I I had done something wrong, but the error was easily reproducible. If the theory is moved in slow motion right display. But, as already mentioned, in normal "operating tempo" "shifts" to the zero position so that the back closed, the previously zeroed display value, Caliper, anything, but not zero indicates. Maybe a Monday device? Go back !
