The 350 Phase Meter has a frequency range of 10Hz to 2MHz. 1 mV to 2 V rms or 50 mV to 100 V rms in two switch selected ranges. Input impedance of 1 Mohms shunted by 26 pF. DC voltage output is proportional to measured phase angle at 10 mV/degrees. Accuracy of phase out signal of ±(0.1 degree + 0.3%) of phase angle measured full scale.
