5.4 Operating modes
The TrueBlend operates in three different operating modes:
• Gravimetric mode: all components are metered and weighed in sequence.
• Volumetric mode: all components are metered in sequence without weigh-
ing.
• Combined mode: a gravimetric cycle is followed by an adjustable number
of volumetric cycles.
