Abstract
It is suggested for a balance with one or several weighing cells (1-4, 31) with a total of at least eight wire strain gauges (D.sub.1 -D.sub.4, S.sub.1 -S.sub.4), four of which (D.sub.1 -D.sub.4) are expanded under load and four (S.sub.1 -S.sub.4) compressed under load, in which the eight wire strain gauges are connected together circularly in series so as to form a single Wheatstone bridge which is supplied with voltage along a diagonal (12, 13) (vertical diagonal) and the output signal is taken off along the other diagonal (14, 15) (horizontal diagonal) that a signal is additionally tapped off along the upper horizontal chord (16, 17) and along the lower horizontal chord (18, 19). This makes possible a corner-load adjustment for the balance utilizing the additional signals.
