DC NOTES
1. 20% overrange except on 1000V and 3A.
2. Add the following to “ppm of range” uncertainty; 100mV 15ppm; 1V and 100V 2ppm; for Model 2750 1Ω and Dry Circuit Ω
40ppm; 10→1MΩ 2ppm, for Models 2700/2701 100Ω 30ppm, 20mA and 1A 10ppm, 100mA 40ppm.
3. ±2% (measured with 10MΩ input resistance DMM, >10GΩ DMM on 10MΩ and 100MΩ ranges). For Dry Circuit Ω, ±25% with
Input HI connected to Sense HI; with Sense HI disconnected add 30mV.
4. Relative to calibration accuracy.
5. For signal levels >500V, add 0.02ppm/V uncertainty for portion exceeding 500V.
6. Specifications are for 4-wire Ω, 1Ω, 10Ω, and 100Ω with offset compensation on. With 77XX plug-in modules, LSYNC on. With off-
set compensation on, OPEN CKT. VOLTAGE is 12.8V. For 2-wire Ω add 1.5Ω to “ppm of range” uncertainty. 1Ω range is 4-wire only.
7. Must have 10% matching of lead resistance in Input HI and LO.
8. Add the following to “ppm of reading” uncertainty when using plug in modules:
9. Add 1.5V when used with plug in modules.
10. For RATIO, DCV only. For AVERAGE, DCV and Thermocouples only. Available with plug in modules only.
11. Add 6µV to “of range” uncertainty when using Models 7701, 7703, and 7707, and 3µV for Models 7706 and 7709.
12. Auto zero off.
13. For LSYNC On, line frequency ±0.1 %. For LSYNC Off, use 60dB for ≥ 1PLC.
14. For 1kΩ unbalance in LO lead. AC CMRR is 70dB.
15. Speeds are for 60Hz (50Hz) operation using factory defaults operating conditions (*RST). Autorange off, Display off, Limits off,
Trigger delay = 0.
16. Speeds include measurements and binary data transfer out the GPIB or ASCII data transfer for Ethernet and RS-232 (reading ele-
ment only).
17. Sample count = 1000, auto zero off (into memory buffer).
18. Auto zero off, NPLC = 0.01 (Models 2700 and 2750), NPLC = 0.002 (Model 2701).
