[3] 20% over range on all ranges except 300 Vdc and 1 Adc ranges
[4] Specifications are for 4-wire ohms function or 2-wire ohms using Scaling to remove the offset.
Without Scaling, add 1 additional error in 2-wire ohms function.
[5] 1 year accuracy. For total measurement accuracy, add temperature probe error.
