Offering high bandwidth and exceptional performance, the WT3000 is designed for energy efficiency measurements and enables products with standby power modes to be tested according to IEC 62301 Ed 2.0 and EN50564. It supports 50/60 Hz (10/12 cycles) harmonic, inter-harmonic and flicker measurement and analysis, as required by IEC61000 standards.

For the evaluation of motors and inverters, a special version is available that enables the motor and total efficiencies to be measured simultaneously.  The Transformer Version has enhanced accuracies at low PF.
