DC, Resistance, and Temperature Accuracy Specifications
DC, Resistance, and Temperature Accuracy Specifications
[1] Specifications are for 1 hour warm up and 6½ digits, slow AC filter.
[2] Relative to calibration standards.
[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 4 additional error in 2-wire ohms function.
[5] 1 year accuracy. For total measurement accuracy, add temperature probe error.
[6] Thermocouple specifications are not guaranteed when 34907A module is present.
