• For 2.5 element programmed units, degrade accuracy by an additional 0.5% of reading.
• For 1A (Class 2) Nominal, degrade accuracy by an additional 0.5% of reading.
• 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 autoscale 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.
