Related to volume flow (MV = measured value).
These values are related to the pulse / frequency output.
The additional typical measuring deviation for the current output is ±10 μA.
For information refer to Measuring accuracy on page 14.
Repeatability ±0.1% of MV, minimum 1 mm/s
Long term stability ±0.1% of MV
