Accuracy
DC Accuracy For the Low-Gain or High-Gain Amplifier Path:
±0.2% of Amplitude ± 0.05% of Offset ± 500 µV
(within ±10 °C of self-calibration temperature)
±0.4% of Amplitude ± 0.05% of Offset ± 1 mV
(0 °C to 55 °C)
All paths are
calibrated for
amplitude and
gain errors. The
Low-Gain and
High-Gain
Amplifier Paths
also are
calibrated for
offset errors.
Calibrated for
high impedance
load.
For the Direct Path:
Gain Accuracy: ±0.2% (within ±10 °C of self-calibration
temperature)
