5.4.1 Scale and offset

The Scale and Offset values displayed in Menu 2.1 are the actual numbers used in the
calculation of displayed Tension (unless a lookup table is being used).

The menu for setting scale and offset values,

2.1 TENSION CAL METHOD 1

, is

shown below. Select Item 2 and enter the full-scale Tension sensor output in the
specified units. The full-scale value corresponds to the load at 20 mA on a 4-20 mA
device, or to the load at 5.00 V, on a 0-5 Vdc device. Then select Item 3 and enter
the Tension offset. The offset corresponds to the load at 4 mA on a 4-20 mA device,
or to the load at 0.0 V, on a 0-5 Vdc device.

5.4.2 Two point live calibration

The two point live calibration method allows the Tension input to be calibrated using
actual weights or measured line Tensions in the field. The two-point live calibration
automatically calculates the Scale and Offset values described in section 5.4.1, based
on the applied weights. When you perform a two-point live calibration, the previous
Scale and Offset values are automatically updated to reflect the new calibration. This
eliminates the chance of conflicting calibration values in the two modes. If the exist-
ing numbers are significant, they should be recorded before beginning this procedure.

The menu for using the two point live calibration functions,

2.2 TENSION CAL

METHOD 2

, is shown below. Two known Tension loads are required to perform

this calibration. Ideally these loads are near each end of the normal working load
range, but not at either full-load or zero load.
