9.Press Force 0 to change the setting from Off to On. The curve then passes through the origin of the coordinate system.

Note: This may have an adverse effect on the correlation coefficient (r2).

10.Press Table to display the table again.

11.When the table has been completed and the curve type has been chosen, press Done when the graph is displayed or Exit when the table is displayed. Go to section 6.1.1.4 on page 70.

Calibration by entering the formula

1. Press Enter Formula and press Next.

2.Press the formula key.

A list of available formulas (linear and 2nd and 3rd order polynomial) is displayed. Up to 4 coefficients can be entered, depending on the selected formula. Press the required formula.

3.Depending on the selected formula, the required coefficients (a, b, c...) are displayed. Press the coefficient keys and enter the corresponding values via the alphanumeric keypad. After each entry, press OK to confirm.

Note: The coefficients can have 5 digits and can have a positive or a negative sign.
