The front cover cannot be turned open by 180 deg.

when there is no extra space between units.

(A) Polarity Indicator LED

(B) Ratio/Bias Display

(E) Zero Adj.

(F) Span Adj.

(D) UP/DOWN Control

Top: Ratio

Bottom: Bias

• 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 = K(Xi + B) (proportional)

Xo = K(Xi + 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 %
