Make a note of both values.

Start the return stroke.

Select the "System Options" system function key.

In the "System Options" submenu, select the "Calibrate analog Inputs"

command.

Select the "Analog Input 1".

Enter the noted value (in kN) into the "Value Machine" parameter.

Enter the noted value (in kN) into the "Value Reference" parameter.

Select "Calculate & Save" using the arrow key.

Confirm the entry by pressing the "Enter" key. The control calculates

the new calibration value from the two entered values and displays the
result.

Figure 11-3: "Force Calibration" submenu

Subject the force sensor again to a load.

Compare the measured value of the reference measuring system with

the measured value of the machine.

Repeat the calibration process if the values do not coincide.

The calibration affects the value of the force offset.

After the calibration, check whether the value has changed.

After a large change has taken place, set the force offset again. For

more information on setting the force offset, please see chapter
"11.1 Setting the force offset".

If there are large calibration errors, you can reset the calibration value to "1".

Select the "Calibration Init" command.

When using the optional analog output 2 to measure quality-relevant
dimensions, regular inspections or calibrations should be made.

Proceed as described at "Analog input 1".
