Accuracy Specifications
Accuracy is expressed as ±(% of reading + number of last significant digits) for readings falling within 10% to 100% of full scale of range.
Valid after 30 minutes of warm up time, operation at 23 °C + 5 °C, <75% R.H. and slowest measurement speed.
880 only: When selecting a test signal level of 0.3V, the measurement accuracy is twice the accuracy listed in the table.
