0000001801 POTENTIOMETER ADJUSTMENT

Potentiometer adjustment 1. Applied voltage: Vi 2. Boost pressure = P1kPa {P2 mmHg} 3. Set the control lever at the adjusting point. Position the dummy bolt against the lever and fix. 4. Assemble the potentiometer to obtain output voltage V1 (V) at the fixed position. 5. After mounting the potentiometer, remove the dummy bolt.
