Set DHXFormer Ratio
A step-up transformer is used in ESP applications. Program the transformer ratio in terms of the
volts out of the transformer for each volt in. For example, if a transformer is rated at 480 Volts
and you have selected a tap reading 2256 Volts, then set the transformer to 2256/480 = 4.70.
Use the up and down arrow buttons as needed to highlight DHXFormer Ratio. Press the Select

Use the left and right arrow buttons to select a digit. Use the up and down arrow buttons to
change the selected digit.
The selected digit is just to the right of the insert in the field.
