The measurement board must be printed using the PCB file (Source file repository), with components soldered onto
it by following the steps described below and illustrated in the following figure :
* Step no. 1: test divider bridge
Pour chacune des voies de mesure, nous avons installé un pont diviseur il est necéssaire de tester la valeur des résistance
pour corriger les coefficients (coeff_p0, coeff_p1, coeff p2, coeff_p3) dans le code Ohmpi.py.
* Step no. 1: installation of the 1-Kohm resistors with an accuracy of ± 1%.
* Step no. 2: installation of the 1.5-Kohm resistors with an accuracy of ± 1%.
* Step no. 3: test divider bridge

n_{\mathrm{offset}} = \sum_{k=0}^{N-1} s_k n_k
* Step no. 2: installation of the 1-Kohm resistors with an accuracy of ± 1%.
* Step no. 3: installation of the 1.5-Kohm resistors with an accuracy of ± 1%.
* Step no. 4: installation of both the black female 1 x 10 header and the 7-blue screw terminal blocks
* Step no. 5: installation of the 50-Ohm reference resistor ± 0.1%
* Step no. 6: addition of both the ADS115 directly onto the header (pins must be plugged according to the figure) and the LM358N operational amplifiers (pay attention to the direction).
