DC NOTES
1. Add the following to “ppm of range” uncertainty:1V and 100V, 2ppm; 100mV, 15ppm; 100Ω, 15ppm; 1kΩ–
<1MΩ, 2ppm; 10mA and 1A, 10ppm; 100mA, 40ppm.
2. Speeds are for 60Hz operation using factory default operating conditions (*RST). Autorange off, Display off,
Trigger delay = 0.
3. Speeds include measurement and binary data transfer out the GPIB.
4. Auto zero off.
5. Sample count = 1024, auto zero off.
6. Auto zero off, NPLC = 0.01.
7. Ohms = 24 readings/second.
8. 1 PLC = 16.67ms @ 60Hz, 20ms @ 50Hz/400Hz. The frequency is automatically determined at power up.
9. For signal levels >500V, add 0.02ppm/V uncertainty for the portion exceeding 500V.
10. Add 120ms for ohms.
11. Must have 10% matching of lead resistance in Input HI and LO.
12. For line frequency ±0.1%.
13. For 1kΩ unbalance in LO lead.
14. Relative to calibration accuracy.
15. Specifications are for 4-wire ohms. For 2-wire ohms, add 1Ω additional uncertainty.
16. For rear inputs, add the following to temperature coefficient “ppm of reading” uncertainty 10MΩ 95ppm,
100MΩ 900ppm. Operating environment specified for 0º to 50ºC and 50% RH at 35ºC.
