1. See the first sentence in Table 11 for a complete explanation of accuracy.
2. AC conversion for Model 83 is ac coupled and calibrated to the rms value of a sinewave input.
3. AC conversions for Models 85 and 87 are ac coupled, true rms responding, and valid from 5% to 100% of range.
4. See note 3 in Table 11.
5. Below a reading of 200 counts, add 10 counts.
