Maximum (Max) and Minimum (Min) Range Values
When the range mode is Manual, you can set the maximum (Max) and minimum (Min) values within the following
range.
–9.999 T to 9.999 T
• The output is 0 V if a measurement function is not selected or if there is no numeric data.
• If a scaling factor such as a VT ratio, CT ratio, or power coefficient is applied to a voltage, current, or power
value and scaling is enabled, the WT1800 produces 100% output (5 V) when the scaled measured value is
the same as the scaled rated value (measurement range × scaling factor).
• For Σ functions, the WT1800 produces 100% output (5 V) when the measured value is equivalent to the
value that is measured when all of the elements in the group are at their rated values. When the elements
have different scaling factors, the WT1800 produces 100% output (5 V) when the scaled measured values
are the same as the scaled rated values (measurement range × scaling factor).
