4. Line up the holes of the multi-scale option module with the holes located on the right side of the notch on
the option-mounting bracket.
5. Install the (4) aluminum standoffs in the holes with the (4) screws on the underside of the bracket
(labeled ETH). Refer to Figure 2-4 for configuration.
6. Position the multi-scale option module on the standoffs so the ribbon cable points away from the notch
on the option-mounting bracket. Install the (4) hex nuts to secure the option board.
7. If more than one SBM module is being used, connect the 6" option ribbon cable from J1 to J2 of the next
option.
8. The last option in the chain will use a 22-30-35454 10" ribbon cable (optional) to connect the option
module to the main board.
9. Reinstall the enclosure bottom plate.

ARAMETERS
Multi-scale setup parameters beginning at P108 → P142 are used to setup the multi-scale option module.
Each scale is selected as an instance, 1 → 4 on the Model 675 and 1 → 2 on the Model 672. Refer to page
3-39 for complete configuration details.

ALIBRATION
A printout of the A/D calibration information accompanies each multi-scale option module on a sheet inside
the anti-static bag with the circuit board. These parameters must be entered into the Module 672/675 in
order for it to read the scale input accurately. A sample printout appears below:

The values indicated in bold define the A/D calibration values for the multi-scale option module. They must
be keyed into and stored in their respective parameters for accurate operation. The serial number (P61122)
is intended to allow you to associate these setup parameters to a specific multi-scale option module. Contact
GSE with the part number and serial number of the multi-scale board if the calibration sheet is misplaced.
Refer to page 5-8 for complete details on A/D calibration.
