How does the scale and offset work in Display Scalar?

By default the display scalar is set to x1 and one unit of measure on the input equals one unit of measure on the display. As an example if you have a Volt Meter model and ’Display Scalar’ is set to x1, then 1 volt on the input would equal 1 volt on the display. 

You can use scale to multiply the displayed value and offset to add to the displayed value: 

  • If you want 1 volt on the input to equal 10 volts on the display, then enter 10 in the Scale box. 
  • If you want the displayed value to be the input value plus 3 volts, enter 3 in the Offset box.

If you set both a scale and an offset, the APM will apply the offset first followed by the scale. For example, applying a scale of 0.01 and an Offset of 2 will result in the values below. Applying 20V to the meter the displayed value would be (20V + 2) x 0.01 = 0.22V.
