AR-LXPA100 is a PA amp applied for some inputs such as voltage output accelerometer, etc.
See Section 6 for the specifications.
Cautions on Using PA Amp
■ Calibration
It is suggested that you use the 0.01 V range of the LX PA amp after turning on the power for 10 minutes or
more, and then executing manual calibration. In order to execute the manual calibration for precise
measurement, click the button on the toolbar of the LX Navi. Also it is recommended that you use the
balanced input mode for precise measurement. Also, the balanced input mode is recommended for precise
measurement.
■ Input Connection and Grounding
When using a battery-powered sensor or IEPE sensor
Input Mode: Balanced (Bal) mode
Whenever possible, connect the LX frame ground (FG) to ground.
When using the AC-powered sensor amp
Input Mode: Balanced (Bal) mode
Always connect the frame ground (FG) of the input signal source and the LX frame ground (FG) to ground.
■ Handling a reserved input terminal
Since the input impedance of the input amp is a high impedance of 1MΩ, there is a possibility that external
disturbance noise will be mixed with the data. You can set the maximum of the input range or short-circuit
the input to prevent interference by external noise.
