The front cover cannot be turned open by 180 deg.  
when there is no extra space between units.  
How to Set the Ratio  
Xo = KXi + B (proportional)  
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.  
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 %.  
The Polarity Indicator LED (A) is red when the set value is in  
positive range, green when in negative range.  
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 %.  
How to Set the Bias  
3) Apply the calculated zero point input again and check the  
output Xo.  
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.  
4) If the output has been shifted, go through (1) through (3)  
again.  
The Polarity Indicator LED (A) is red when the set value is in  
positive range, green when in negative range.  
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%
