Embodiment Construction
[0031] exist figure 1 A high-resolution electronic precision balance is shown in , which in this example is capable of mass comparisons in all precision classes according to OIMLR111-1 and according to ASTME617-13.
[0032] The precision weighing device comprises a weighing cell 14 with a base 12 into which a weighing system 10 , not shown in detail, is mounted. Furthermore, the weighing cell 14 includes a weighing chamber 16 , which is formed by a draft shield with adjustable side walls 18 , a front wall 20 and a rear wall 22 . The weighing chamber 16 can be separated from the surroundings by means of a draft shield. The weighing pan 24 is used to support weighing objects.
[0033] Electronic evaluation system 26 embodied here as a separate component is electrically coupled via cable 28 to weighing cell 14 . A display unit 30 coupled to the evaluation system 26 serves both as a display and as a data input unit.
[0034] In particular, a processor 32 is installed in electr...
