  • How to Set the Ratio Turn the Ratio/Bias Selector (C) to the top. The Ratio/Bias Display (B) shows the current ratio (0.10 – 4.00). Press UP/DOWN Control (D) until the display shows a desired set value. The Polarity Indicator LED (A) is red when the set value is in positive range, green when in negative range.
  • How to Set the Bias Turn the Ratio/Bias Selector (C) to the bottom. The Ratio/Bias Display (B) shows the current bias (0 – 100%). Press UP/DOWN Control (D) until the display shows a desired set value. The Polarity Indicator LED (A) is red when the set value is in positive range, green when in negative range.
  • Fine Calibration Equation: Xo = KXi + B (proportional) Xo = KXi + B + 100 % (inverted) 1) Calculate the input signal Xi which results in 0 % output. Apply the calculated input and adjust with Zero Adj. (E) the output Xo to 0 %. 2) Calculate the input signal Xi which results in 100 % output. Apply the calculated input and adjust with Span Adj. (E) the output Xo to 100 %. 3) Apply the calculated zero point input again and check the output Xo. 4) If the output has been shifted, go through (1) through (3) again. The unit is factory set and calibrated to the following ratio and bias values. Proportional characteristics: ratio (K) = 1, Bias (B) = 0% Inverted characteristics: ratio (K) = -1, Bias (B) = 0%
