Verification Box Assembly
This Verification Box provides more accurate voltages than a direct connection to
the 5520A. The 5520A uses a divider with a 50 Ω output impedance when
sourcing <330 mV. Due to variations in the 1730 input impedance, the actual
applied voltage is less than the programmed voltage. Using an external divider
where the parallel resistance is ~30 Ω allows calculation of the applied voltage
with confidence that the 1730 input loading will not significantly impact the
applied voltage.
Fluke recommends using a verification box that has a divider with 30 Ω across
the 1730 input and 10 kΩ in series with high side of the input. See Table 5 for
instructions on how to make the verification box.
