Step 3. Set Calibration Numbers
1. Set three-position switch to calibrate (down) position)
2. Turn Gain Potentiometer to dial in calibration numbers.
3. If two sensors are wired, follow this procedure for both channels.
⇒
If you are using Helm Panel Software select the SET CAL NO. Menu. Adjust gain balance pot until
calibration numbers are correct for channel 1 and
channel 2.
Always make sure that the three-position switch is in ON (top) position for
Normal operation.
The remaining setup procedures can be accomplished with the Run Mode
bit in either Bypass, Peak or Monitor Parts Mode. However, the Bypass
Mode should only be used when setting calibration values or zero
balancing the sensor input.
Step 4. Set Machine Capacity Scale
The three position switch should be placed in the ON (top) position.
This setting is based off of one channel. It represents the maximum allowable load or tonnage from one sensor
location. Integer N10:14 should be set from your operator interface.

Setting Machine Capacity Scale using (1) two channel force module:
If 2 sensors are installed on the left and right sides of a 60 ton press, set the Scale to 30 (maximum capacity of
one sensor).
Use the following table as a reference for setting the Machine Capacity Scale for a single force module installation
with two sensors. Divide the press/machine capacity by the number of sensors (2) and set Scale to the result.

If 2 sensors are installed in the tooling rather than on the press structure, set the Machine Capacity Scale to the
highest load/tonnage of one sensor.
