The emphasizes that the meter uses True RMS for accurate AC measurements on non-sinusoidal waveforms (e.g., VFDs, switch-mode power supplies). For pure sine waves, standard meters work, but for distorted signals, True RMS is essential. The manual specifies an accuracy of ±1.2% for 50/60Hz and ±3% for 40Hz–1kHz.
The ZM-7205A is a sophisticated driver designed for mid-power motor drive applications. It leverages large-scale integrated circuits to replace older hardware designs, resulting in high noise immunity and rapid response times. This driver is specifically designed for three-phase DC brushless motors equipped with Hall sensors or operating in a sensorless (no-Hall) mode.
