2. Use the transformer power supply circuit stipulated in the figure below for allowable load shorted time measurement and output noise voltage
3. The output noise voltage values shown are peak values read with a VTVM. However, an AC stabilized (50 Hz) power supply should be used to
measurement.
minimize the influence of AC primary side flicker noise on the reading.
