[3] Specications are for amplitude of sine wave input > 5% of range. For inputs from 1% to 5% of range and <50 kHz, add 0.1% of range extra error. For 50 kHz
to 100 kHz, add 0.1% of range extra error.
[4] Plus 0.025 V of error per 1 V after the rst ±400 VAC.
[5] Specications are for sine wave input > 5% of range. 0.1% errors will be added when the range of input sine wave is 1% to 5%.
[6] 30 seconds OFF after 30 seconds ON is recommend for the continuous current that higher than DC 7 A or AC RMS 7 A.
