1. For DC: Specifications are for 60-minute warm-up, aperture of 10 or 100 NPLC, and auto zero on. For AC: Specifications are for 60-minute warm-up, slow
AC filter, sine wave.
2. 20% overrange on all ranges, except 1,000 V DCV, 750 ACV, 3 A AC, and diode test.
3. Relative to calibration standards.
4. Add this for each °C outside TCAL ± 5°C.
5. Specifications are for sine wave input > 0.3% of range and > 1 mVrms. 750 ACV range limited to 8 x 107 Volt–Hz.
6. Low-frequency performance: three filter settings are available: 3 Hz, 20 Hz, 200 Hz. Frequencies greater than these filter settings are specified with no
additional errors.
7. Specifications are for 4–wire ohms function or 2–wire ohms using math null for offset. Without math null, add 0.2 Ω additional error in 2-wire ohms
function.
8. Specifications are for sinewave input > 1% of range and > 10 µA AC.
9. Specifications are for the voltage measured at the input terminals. The 1 mA test current is typical. Variation in the current source will create some
variation in the voltage drop across a diode junction.
10. Actual measurement range and probe errors will be limited by the selected probe. Probe accuracy adder includes all measurement and ITS-90
temperature conversion errors PT100 Ro settable to 100 Ω ±5 Ω to remove the initial probe error.
11. Specifications are for 60-minute warm-up and sine wave input unless stated otherwise. Specifications are for 1-second gate time (7 digits).
12. Applies to sine and square inputs ≥ 100 mV. For 10 mV to < 100 mV inputs, multiply % of reading error x10.
13. Amplitude 10% to 120% of range and less than 750 ACV.
14. Square wave input specified for 10 to 300 kHz.
15. Specifications are for using Math Null zeroing. High dissapation factor capacitors may show different results than a single frequency measurement. Film
capacitors usually have lower dissapation factors than other dielectrics.
