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.

valid only for

high impedance.

For the Direct Path:

Gain Accuracy: ±0.2% (within ±10 °C of self-calibration

temperature)

Gain Accuracy: ±0.4% (0 °C to 55 °C)

DC Offset Error: ±30 mV (0 °C to 55 °C)
