DC NOTES
1. Add the following to “ppm of range” uncertainty:1V and 100V, 2ppm; 100mV, 15ppm; 100W, 15ppm;
1kW– <1MW, 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 1kW unbalance in LO lead.
14. Relative to calibration accuracy.
15. Specifications are for 4-wire ohms. For 2-wire ohms, add 1W additional uncertainty.
16. For rear inputs, add the following to temperature coefficient “ppm of reading” uncertainty 10MW 95ppm,
100MW 900ppm. Operating environment specified for 0° to 50°C and 50% RH at 35°C.
