IV. CALIBRATION PROCEDURE

(See Safety Warning, on page 1)

The SIMG is factory calibrated, but readjustments to the OFFSET and MAX trimpots can

be made to customize for a particular signal input requirement. It may be necessary to

repeat the calibration steps to achieve accurate settings.

A. Unidirectional Voltage Following Calibration

See figure 10 on page 12.

1. Apply 0V DC input signal (or connect SIG and COM terminals).

2. Monitor the KBMG output and adjust the OFFSET trimpot on the SIMG for the

desired minimum setting.

3. Apply the maximum voltage input signal.

4. Monitor the KBMG output voltage and adjust the MAX trimpot on the SIMG for the

desired maximum setting.

B. Unidirectional Potentiometer Operation Calibration:

See figure 11A, B or C on page 13.

1. Set potentiometer to 0% rotation (fully counterclockwise).

2. Monitor the KBMG output and adjust the OFFSET trimpot on the SIMG for the

desired minimum setting.

3. Set potentiometer to 100% rotation (fully clockwise).

4. Monitor the KBMG output voltage and adjust the MAX trimpot on the SIMG for the

desired maximum setting.
