[1]: 100 mV: the specifications are for AC input voltage of 35% to 120% of range in <20 kHz frequency; 1 V, 10 V, 100 V, 750 V: the specifications are for AC input voltage of 35% to 120% of range (750 V range is limited to 750 Vrms).

[2]: Specifications are for sine-wave inputs >5% of the range. For the 750 VAC range, it is limited to 8 x 107 Volts-Hz. For 5 kHz to 8 kHz, add 0.13% of range additional error

[3]: For 100 μA, 1 mA, 10 mA, and 100 mA ranges, the internal current sensing resistor needs to be cooled when measuring >1 A current for more than 15 minutes.

[5]: Specifications are for 4-wire resistance measurement or 2-wire resistance measurement using the "Relative" operation. ±0.2 Ω additional errors will be added in performing 2-wire resistance measurement without using the "Relative" operation.

[6]: The accuracy specifications are for the voltage measured at the input terminals only. The typical value of the test current is 350 μA. Variation in the current source will cause some variation in the voltage drop across a diode junction.
