[1] Select 6 ½ digit resolution.
[2] The 2-wire ohms resistance verification test is optional (see “Gain Adjustment Considerations” on page 51). For 2-wire ohms using a
multiplexer for the input connections, an additional 4 Ω of error for the relay contacts must be added. Add a 1-second channel delay when
using Fluke 5700 in 2-wire compensated mode. This avoids response time issues with 2-wire compensation when 34980A’s current source
contains a pulse.
[3] Verify only, no adjustment required.
Q: Quick performance verification test points.
