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)

Gain Accuracy: ±0.4% (0 °C to 55 °C)

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