8.2 Stirring rate
The stirring rate can be adjusted in steps from –15 to +15.
The approximate rotational speed for the internal magnetic stirrer
(depends on the product version) can be calculated with the following for-
mula:
Rotational speed/min (r/min) = 125 · Stirring rate
Example:
Configured stirring rate: 8
Rotational speed in revolutions per minutes = 125 · 8 = 1,000
2000
1500

The information on the separately connectable 802 propeller stirrer can be
found in the "802 Stirrer" manual.
8.3 Balance
The sample size and the associated unit can be sent from a connected bal-
ance. The sample size is transmitted as a number with up to ten characters
(including algebraic sign and decimal point).
Sample size and unit are sent as a single character string. They are separa-
ted by a space character. The string is terminated with the ASCII charac-
ters CR and LF.
If the balance sends a negative sample size (e.g. when you are reweighing
a sample), then the algebraic sign is adopted. The algebraic sign is, how-
ever, ignored for the calculations.
