DC NOTES
1. For the following ranges, add 4ppm to the range accuracy specification: 100mV, 10Ω, 100Ω, 10mA,
100mA, and 1A. Dry Circuit function add 40ppm.
2. Speeds include measurement and binary data transfer out the GPIB.
3. Speeds are for 60Hz (50Hz) operation using factory default operating conditions (*RST).
Autorange off, Display off, Trigger delay = 0.
4. Sample count = 1024, auto zero off.
5. Auto zero off, NPLC = 0.01.
6. Ohms, 17 (15) readings/second.
7. 1 PLC = 16.67ms @ 60Hz, 20ms @ 50Hz/400Hz. The frequency is automatically determined at
power up.
8. For signal levels >500V, add 0.02ppm/V uncertainty for the portion exceeding 500V.
9. Add 120ms for ohms.
10. Must have 10% matching of lead resistance in Input HI and LO.
11. For line frequency ±0.1%.
12. For 1kΩ unbalance in LO lead.
13. Relative to calibration accuracy.
14. Specifications are for 4-wire ohms. For 2-wire ohms, add 1Ω to "ppm of range" uncertainty. 10Ω
range is for 4-wire only.
15. Offset compensation on.
16. Sense LO input must be referenced to Input LO. Sense HI input must not exceed 125% (referenced
to Input LO) of range selected. Sense input has 100mV, 1V and 10V ranges.
17. When properly zeroed using REL function.
18. For rear inputs, add the following to Temperature Coefficient "ppm of reading" uncertainty: 1MΩ
25ppm, 10MΩ 250ppm, 100MΩ 2500ppm. Operating environment specified for 0°C to 50°C and
50% RH at 35°C.
