1.  Specifications are for 1 hr warm-up and 6½ digits, slow ac filter.
2.  Relative to calibration standards.
3.  20% over range on all ranges except 1000 Vdc and 750 Vac 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.  750 V range limited to 100 kHz or 8 x 107 Volt-Hz.
6.  Typically 30% of reading error at 1 MHz.
7.  Specifications are for 4-wire ohms function or 2-wire ohms using Math Null. Without Math Null, add 0.2 Ω addition1a0l3e.6rror in 2-wire ohms function.
8.  Input > 100 mV. For 10 to 100 mV inputs multiply % of reading error x 10.
mm
9.  Accuracy specifications are for the voltage measured at the input terminals only. 1 mA test current is typical. Variation in the current source will create
some variation in the voltage drop across a diode junction.
