1. Specifications are for 60-minute warm-up, integration setting of 10 or 100 NPLC, auto-zero on, AC slow filter. ACAL run within the last 2 days.
2. 20% over range on all ranges, except 1000 DCV, 750 ACV, 10 DCA, 3 DCA, 10 ACA, 3 ACA, and diode test have 0%.
3. Relative to calibration standards.
4. The 10 A range is only available on a separate front panel connector. Add 2 mA per amp for inputs greater than 5 Arms.
5. Add this for each °C outside TCAL ±5°C.
6. Add this for each °C outside the last ACAL ±2°C.
7. Add this for each °C outside ACAL ±2°C.
8. 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.
The 100 M and 1 G ohm ranges are 2-wire only. See the manual for low power ohms specification and measurement currents
9. For each additional volt over ±500 V add 0.02 mV of error.
10. 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.
11. See user manual for details.
12. 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.
13. The internal reference junction uses the U1180A or equivalent adapter. This has a typical performance of ±1.0°C.
This internal reference junction can be adjusted for better accuracy. An external reference junction can also be used.
14. Specifications are for sinewave input > 0.3% of range and > 1 mVrms. 750 ACV range limited to 8 x 107 Volt–Hz.For each additional volt over 300 Vrms
add 1 mVrms of error.
15. 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.
16. Specifications are for sinewave input > 1% of range and > 10 µArms.
17. Specifications are for sine wave input unless stated otherwise.
18. Square wave input specified for 10 Hz– 300 kHz for 1 second aperature. For shorter aperatures the minimun frequency requires > 2 cycles.
19. Input > 100 mV. For 10 mV to 100 mV inputs, multiply % of reading error x10. Amplitude 10 – 120% of range except 14 – 100% for the 750 ACV range.
Specifications are for 1-second gate time (7-digits).
20. 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.
21. The second burden voltage can be obtained by using the 10 A input range.
22. Sample rate (actual): 50.118 kHz (Aperture = 19.953 µs).
