The 6105A and 6100B both meet all accuracy requirements of power quality testing to the IEC 61000-4 series of standards. The 6100B can be used to type test 0.1% to 2% energy meters. The 6105A is used when you need the highest accuracy available for calibrating secondary standard meters, energy revenue meters, and type test applications. The 6105A proved the accuracy required for secondary standards such as those produced by Radian Research, Zera, and MTE.
The instruments produce a variety of complex signals including flicker, harmonics, dips and swells, interharmonics, fluctuating harmonics, and simultaneous application.
