Note: This table does not take into account possible distortion of the measured signal (THD) because of the physical limitations
of the current sensor (saturation of the magnetic circuit or of the Hall-effect cell). Class B under standard IEC61000-4-30.
15.4. CLASS B UNDER STANDARD IEC 61000-4-30
15.4.1. CONFORMITY OF THE DEVICE
The device and its Power Analyzer Transfer 2 operating software are compliant with class B of standard IEC61000-4-30 for the
following parameters:
 Industrial frequency,
 Supply voltage amplitude,
 Flicker,
 Supply voltage brownouts,
 Temporary overvoltages at industrial frequency,
 Supply voltage blackouts,
 Voltage transients,
 Supply voltage unbalance,
 Voltage harmonics.
Remark: To ensure this compliance, trend recordings (Trend mode) must be made with:
 A recording period of one second,
 The quantities Vrms and Urms selected,
 The quantities V-h01 and U-h01 selected.

15.4.3. UNCERTAINTY OF THE REAL-TIME CLOCK
The uncertainty of the real-time clock is 80 ppm at most (device 3 years old used at an ambient temperature of 50°C). With a new
device used at 25°C, this uncertainty is only 30 ppm.
