LDX-3A

5.0: Setting up the Transducer and LDX-3A (continued)

M-1633/0905

STEP 3 - Setting Bi-Polar Full-scale Output

1. Move the transducer to the position where maximum LDX-3A output is required.

2. If the polarity of the output is wrong, move the Polarity (FR) links to the R position (see link diagram).

3. Move the RANGE link between 1 and 6 until the LDX-3A output is near the required value.

4. Adjust the Fine Gain control to give the required output.

5. A bi-polar output has now been set, proceed to step 5. If a uni-polar output is required, proceed to step 4.

Example: ±10Vdc is required from a ±1mm transducer. Set the transducer to the +1mm position and set the output to

10V.

If your transducer is known to be outside of the standard sensitivity range, the X2 or DIV2 links will have to be used.

See section 5.3.
