Task 7 Millivolt/Volt Calibration
If you are using mV/V Calibration for your calibration type, complete
the following procedure. If not, complete Task 5 Gain/Delta K
Calibration on page 135 or Task 6 Gain/Linearization Calibration
on page 142.
Millivolt/volt calibration is used for transducers that have two different
slopes (positive and negative).
In this calibration process, system software calculates conditioner Delta
K Gain and Gain values from previously measured mV/V values under
both tension and compression.
The slope and gain values are derived from, and are relative to, the
output of the load cell transducer as follows:
Where:
Compression is specified using the Neg Compression or Pos
Compressive entry box on the Calibration submenu or tab.
Tension is specified using the Neg Tension or Pos Tension
entry box on the Calibration submenu or tab.
Positive Tension
Slope (mv/V)
Negative Compression
Slope (mV/V)
Delta K Gain
Compression mV/V
Tension mV/V
