30ppm, 1K→1MΩ 2ppm, 10mA and 1A 10ppm, 100mA 40ppm.
3. ±2% (measured with 10MΩ input resistance DMM, >10GΩ DMM on 10MΩ and 100MΩ
ranges).
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, 100Ω with offset compensation on, 77xx plug-in module with
LSYNC and offset compensation on. With offset compensation on OPEN CKT. VOLTAGE is
12.8V. For 2-wire Ω add 1Ω additional uncertainty.
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 1V 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 6μ V to “of range” uncertainty when using Models 7701, 7703, and 7707, 3μV for Models
7706, 7709, and 7710.
12. Auto zero o ff.
13. For LSYNC On, line frequency ±0.1%. For LSYNC Off, use 60dB for ≥ 1PLC.
