AUTOMATIC DISTORTION METER AC MILLIVOLT METER The GAD-201G distortion meter is aimed at total harmonic distortion (THD) and AC voltage The GVT-427B/417B Series is a compact analog AC millivoltmeter ideal for low level voltage measurement at audio frequency range, from 20 ~ 20kHz. Frequency and voltage are displayed measurements with a remarkable 300 V full scale sensitivity. The GVT-427 has dual independent simultaneously on dual meters, with measurement range automatically switching over full scale. channels that can be used simultaneously or separately for measurement. Voltage scale is separated The frequency keys cover 400Hz, 1kHz, and 10kHz for commonly used measurement frequencies. into 12 ranges, easily accessible by the large rotary selector. The wide measurement range, frequency The output terminals can feed basic waveforms (X) and harmonic distortion (Y) to an external (10Hz ~ 1MHz) and voltage (-70dB ~ +40dB), provides ample headroom for most applications. monitoring device. Residual distortion, including hum and noise, is kept to a minimum level of 0.03%, making the GAD-201G ideal for high-end audio applications.
