 You can use the provided `calibration/calibration.py` script to run a very simple overlay for pump adjustment. Within the file, you can define your used pins (`pinvector`) and the default volume flow provided by the manufacture (`volumeflow`) for the calibration. You can use water and a weight scale for the process. Use different volumes (for example 10, 20, 50, 100 ml) and compare the weight with the output from the pumps. In the end, you can adjust each pump volume flow by the factor:
 
-$\dot{V}_{new} = \dot{V}_{old} \cdot \dfrac{V_{expectation}}{V_{output}}$
+Vnew = Vold \* expectation/output
+
+<!-- $\dot{V}_{new} = \dot{V}_{old} \cdot \dfrac{V_{expectation}}{V_{output}}$ -->
