The DECS-400 uses auto-ranging to display up to four digits of resolution plus a decimal point. If needed,
a multiplier such as k for kilo (1,000) or M for mega (1,000,000) is used. Negative values with magnitudes
greater than 999.9 are displayed with three digits of resolution.

Setpoint

The setpoint field displays the setpoint for the active mode of operation. Table 4 lists the relationship
between the mode of operation and the setpoint field quantity.

Percent of Range

This field displays the setpoint expressed as a percentage of the available adjustment range. The
relationship between this field and the setpoint field is linear. For example, a setpoint adjusted to the
minimum value would be displayed as 0.0%, a setpoint adjusted to the middle of the adjustment range
would be displayed as 50.0%, and a setpoint adjusted to the maximum value would be displayed as
100.0%.
