TAI Model 6400A SO
1. Voltage method - preferred method.
Digital type Multi-meters (DMM) are ideally suited for this type of measurement because of
their high input impedance - usually 10M ohm or greater. The total load resistance should be
between a 200ohm (min) to 1000 (max), precision load resistor of .1% tolerance or better is
recommended.
2. Current method.
Although current is constant in a series circuit, accuracy in this type of measurement is usually less
precise than with the voltage method due to the type of circuitry used in digital multi-meters. Connect a
load resistance (between 200 - 1000ohm) in series with the DMM.
