[2] Relative to calibration standards
[3] 20% over range on all ranges except 300 Vac and 1 Aac 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.
[5] Typically 30% of reading error at 1 MHz, limited to 1x10
[6] Input > 100 mV. For 10 mV inputs, multiply % of reading error x 10.
[7] Specified only for inputs > 10 mA
