EX) 2mV/V

Vout : Output voltage of amplifier when the maximum output of transducer

is inputted

: Bridge proper voltage

: Amplifier gain

: Output sensitivity of transducer (mv/V)

For shunt compensation, error can be occurred by wiring, bridge resistance or

proper voltage while stress analysis is being done. So shunt compensation is

very important when you set the amplifier gain. Also when you use the analogue

transducer (force, torque and pressure etc), please fully understand the size of

transducer and the form of output so that you can select correct amplifier gain

accordingly.

4-11. Filter control

As standard, ST-AM210 has 2 pole standard low-pass filter installed.

Controllable switch is located on the front side of amplifier and the signal noise is

10Hz, 100Hz, 1kHz, 10kHz. Wide-band can be controlled by band pass. This cut-

off frequency is normally originated in 30% (-3dB) of output. For control, please

turn the rotary selector switch located on the front side of the amplifier.
