1.6 Functions of the 4-CH, Medium-Speed Strain Input Module (-B12, -B35, and -NDI)
Initial Balancing (Initial Unbalance Value Adjustment)
When configuring a bridge circuit with a strain gauge, the bridge circuit will not
necessarily be balanced even if the strain of the circuit under test is zero due to the slight
deviation in resistance of the strain gauge, and the measured value may not be zero (the
value in such cases is called the initial unbalanced value.)
Therefore, when taking measurements you must first balance the bridge and, if the strain
is zero, obtain a measured value of zero. This is called initial balancing (setting the initial
unbalanced value to zero).

With the MX100, initial balancing is performed in the ±10000 µ strain range.
Initial balance: The value when the command is executed is taken as the initial
unbalanced value, and the measured value is set to zero.
Reset: The value set during initial balancing is reset to zero. The initial
unbalanced value is used as-is for the measured value.
Note
If the measuring range is changed, the initial balancing is reset.
After a range change, you must redo initial balancing.
