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%
