- Fully adjustable calibrated gain from 1 to 11000
- All bridge completion built-in, including 120- or 1000- and 350-ohm dummies
- Bandpass: 50 kHz (-0.5 dB); 125 kHz (-3.0 dB)
- Input
* Strain Gages: Quarter (120 ohm or 1000 ohm and 350 ohm), half or full bridge (50
to 1000 ohm). Dummy resistors installed
* Transducers: Foil or piezoresistive strain gage types

- Bridge Balance - Method: Counter-emf injection at preamp;
automatic electronic; dual range; can be disabled on front panel
- Shunt Calibration - Circuit (2-level, dual polarity):
* Single-shunt (for stress analysis) across any bridge arm, including dummy gage
* Double-shunt (for transducer) across opposite bridge arms
- Amplifier
* Gain: 1 to 11000 continuously variable
