rent ranges
[4] For sinewave input > 5% of range. For inputs from 1% to 5% of range and < 50 kHz,
add 0.1% of range additional error

[6] Specifications are for 4- wire ohms function or 2-wire ohms using Scaling to remove
the offset. Without scaling, add 1 Ω additional error in 2-wire Ohms function
[7] Input > 100 mV. For 10 mV inputs multipy % of reading error x 10
