 Figure 5 shows the general diagram for the electronic measurement board developed. This figure also displays the test 
 circuit used to test the board in the laboratory, which mimics the behavior of a soil subjected to current injection.

 Electrical resistivity measurements
 ===================================
 
 To measure electrical resistivity with Raspberry Pi, an ADS1115 was introduced, as proposed by Florsch [7]. The ADS1115
-is a 16-bit ADC (Analog-to-Digital Converter), with an adaptable gain. Its value has been set at 1 in this study. The 
+is a 16-bit ADC (Analog-to-Digital Converter), with an adaptable gain. Its value has been set at 2/3 in this study. The 
 input signal value could lie between - to + 6.114 V. The ADS1115 is mounted on a board adapted from an in-house design. 
 Figure 5 shows the general diagram for the electronic measurement board developed. This figure also displays the test 
 circuit used to test the board in the laboratory, which mimics the behavior of a soil subjected to current injection.
