PR/SR balances
If you wish, you can set the display to zero with the tare key Πbefore placing the sample on the pan.
If the parameter "+/–%" is activated in the menu under "+/–Stats" (section 6.1.5), all weighing results
appear in percent of the nominal weight. Switching to the weighing unit is possible.
You can classify your samples according to the measured weight using the Input/Output Module LC-IO
attached to the balance (section 7.3). The outputs will be activated according to the following table:
Active output no. when weight value (wv) is
1 (for 0.3 sec) entered by pressing "M+" or automatically
2 stable
3 wv < Nominal – 2* (–Tol)
4 Nominal – 2* (–Tol) ≤ wv < Nominal – (–Tol)
5 Nominal – (–Tol) ≤ wv < Nominal
6 Nominal ≤ wv ≤ Nominal + (+Tol)
7 Nominal + (+Tol) < wv ≤ Nominal + 2* (+Tol)
8 wv > Nominal + 2* (+Tol)
