1
Software limits. Actual range dependent on sensor type and system dynamics
2
Accuracy figures are the additional error the 685 adds to the measurement, and does not include the
sensor uncertainties.
3
At 25°C
4
Stability measurements done at 25°C. The number is ½ the peak-to-peak deviation from the average
over the measurement period.
