1. Specications are for 60-minute warm-up, integration setting of 10 or 100 NPLC, auto-zero on, AC slow lter. 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. These specications are for typical performance.
5. The 10 A range is only available on a separate front panel connector. Add 2 mA per amp for inputs greater than 5 Arms.
6. Add this for each °C outside TCAL ± 5 °C.
7. Add this for each °C outside the last ACAL ± 2 °C.
8. Add this for each °C outside TCAL ± 2 °C.
9. Specications 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 specication and measurement currents
10. For each additional volt over ± 500 V add 0.02 mV of error.
11. Specications 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.
12. See user manual for details.
13. 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.
14. 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.
15. Specications are for sinewave input > 0.3% of range and > 1 mVrms. 750 ACV range limited to 8 x 10
7
Volt–Hz. For each additional volt over 300 Vrms add
1 mVrms of error.
16. Low-frequency performance: three lter settings are available: 3 Hz, 20 Hz, 200 Hz. Frequencies greater than these lter settings are specied with no
additional errors.
17. Specications are for sinewave input > 1% of range and > 10 µArms.
18. Specications are for sine wave input unless stated otherwise.
19. Square wave input specied for 10 – 300 kHz for 1 second aperature. For shorter aperatures the minimun frequency requires > 2 cycles.
20. 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.
Specications are for 1-second gate time (7-digits).
21. Specications 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.
22. The second burden voltage can be obtained by using the 10 A input range.
