The AR-LXST100 is an input amp applied for strain gauges, strain gauge type sensors and DC inputs.

See Section 6 for the specifications.

Cautions on Using ST Amp

■ Calibration

It is suggested that you use the ST amp after turning on the power for 20 minutes or more, and then perform

manual calibration. In order to perform manual calibration for precise measurement, click the

button on the toolbar of the LX Navi.

■ Input Connection and Grounding

When using sensors:

Input Mode: Balanced (Bal) mode

Whenever possible, connect the LX frame ground (FG) to ground.

When using the AC supply 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 input amp is a high impedance of 1MΩ, it is possible 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 the interference by external noise,
