  1. Specifications are for 1 hr warm-up and 61/2 digits, Slow ac filter
  2. Relative to calibration standards
  3. 20% over range on all ranges except 300 Vdc and ac ranges and 1 Adc and ac current 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 1 x 108 V Hz
  6. 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
  7. Input > 100 mV. For 10 mV inputs multiply % of reading error x 10
  8. Specified only for inputs >10 mA
  9. For total measurement accuracy, add temperature probe error
  10. Thermocouple specifications not guaranteed when 34970A module is present
