15.4. CLASS B UNDER STANDARD IEC 61000-4-30

15.4.1. INSTRUMENT CONFORMITY

The instrument and DataView PowerPad III Control Panel 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
To ensure this compliance, trend recordings (Trend mode) must be made with:
■ Recording period of one second
■ Vrms and Urms selected
■ V-h01 and U-h01 selected

15.4.3. REAL-TIME CLOCK UNCERTAINTY

The uncertainty of the real-time clock is 80 ppm at most (instrument 3 years old used at an ambient temperature of 122°F [50°C]).
With a new instrument at 77°F (25°C), this uncertainty is only 30 ppm.
