• For 2.5 element programmed units, degrade accuracy by an additional 0.5% of
reading.
• For 1A (Class 2) Nominal, degrade accuracy to 0.5% of reading for watts and
energy; all other values 2 times rated accuracy.
• For 1A (Class 2) Nominal, the input current range for accuracy specification is
20% of the values listed in the table.
2
For unbalanced Voltage inputs where at least one crosses the 150V auto-scale
threshold (for example, 120V/120V/208V system), degrade the accuracy to 0.4%
of reading.
3
With reference Voltage applied (VA, VB, or VC). Otherwise, degrade accuracy to
0.2%. See hookup diagrams 8, 9, and 10 in Chapter 4.
4
At least one Voltage input (minimum 20 VAC) must be connected for THD
measurement on current channels.
