Section 5.5.11 Adjustment of Analog Input and Output Boards
3BSE 002 415R701 Rev A 5-75
Adjustment Possibilities on Circuit Boards
Table 5-3 shows the adjustments possible on the various analog input and output boards.
Key to the signs:
Z - Zero, G - Gain, B - Balance, S - Symmetry, V - Variable gain, L1/L2 - Limits
5.5.11.1 Channel Adjustment on DSAI 130
Channel adjustment consists of the following operations:
• Zero-point adjustment Z
• CMRR-balancing (Common Mode Rejection Ratio) B (= suppression of CMV).
Adjustment is normally not necessary except in exchange of components in this circuit.
• Full scale adjustment G.
