* The WCL488 Series offers the selectable full-scale ranges for current and voltage. When a
full scale is selected it changes the full scale of the meter, the current sample, the front panel
adjustments, IEEE controlled adjustments and the analog programming input. This provides an
increase in accuracy and resolution. There are three standard full-scale current ranges and three
standard full-scale voltage ranges.
