The majority of the gain should be assigned to the Input Amplifier, with the Scaling Amplifier used for
fine-tuning. If the filter is enabled, a gain of x2 is automatically introduced.
The input amplifier has a gain range of ×100 to ×1250; the filter gain ×1 or ×2; and the scaling amplifier
has a range of ×1 to ×10. For the strain gage example, if we round off our gain to ×420, any of these
possible settings will work.

For Option C, the LPF gain is typically x2.
For gains of x1 (if the filter is enabled), the following apply:
DBK16
- For a gain of x1 (if the filter is enabled),10K
Ω
resistors R44 and R46 must have been previously
removed (for the low and high channels, respectively).
DBK43A
- For a gain of x1 (if the channel filters are enabled), removal of the following 10 K
Ω
resistors
applies: Ch0 – R144, Ch1 – R244, Ch3 – R444, Ch4 – R544, Ch5 – R644, Ch6 – R744, Ch7 – R844.
