Accuracy of these measurements depends on the DMM used for performing the current/voltage measurements. DMM’s
tend to have more accuracy with small values when measuring current than when measuring voltage. For that reason,
when measuring standby current, it may be necessary to remove the bypass resistors and measure current directly
between the pins of the headers.
