IEC Current
Harmonics Mode
Accuracy
Meets Class II Voltage and Current
measurements as specified in IEC 61000-
4-7:2002 Table 1.
IEC Flicker Pst
Accuracy
+/- 5% for Pst of 0.3 to 5.
Notes:
1. To meet the enhanced specification for 45-65Hz, the firmware version of
the product must be 4.22 or greater, and the “Adjustment Type” must be
“Full Enhanced”. The adjustment type can be viewed in the Unit
Configuration menu under System Configuration (see section 4.9).
2. Zext is the external shunt impedance used and must be less than or
equal to 10 Ohms.
3. For Watts, VA and VAr, voltage and current readings must also meet the
criteria stated for 45-65Hz measurements.
4. All the stated accuracies are based upon a minimum of a 30 minute
warm up period.
5. Common mode specification is only valid for hardware revision 11 or
greater and firmware version 4.13 or greater.
6. If no frequency is measured, then the signal is considered DC for the
purpose of accuracy.
7. Specifications are valid only when applicable voltage and current inputs
are > 10% of range. The exception is harmonics where the specification
is valid when the magnitude of the harmonic is >2% of range.
