.12 Setting the 8939 STRAIN UNIT
For the channel to which the 8939 STRAIN UNIT is assigned, an auto
balancing must be executed through the range setup menu.
Auto balancing is a function by which the reference output level of the
converter is adjusted to the specified zero position.
Before the auto balancing is performed, the strain unit must be warmed up for
approximately 1 hour after power-on to stabilize its internal temperature.
The scaling function can be used to convert an output voltage from a sensor or
similar into a physical quantity. See Section 9.7.2.
Refer to Section 9.3 for the common settings.
