4. Desired display readings are:
4mA = ".0000"
12mA = ".2500"
This example is not as straightforward as the previous three. Notice that
12mA is exactly halfway between 4mA and 20mA. If we assume the input
could go up to 20mA, the display reading would then be 2 x .2500 or
".5000". From Table 1, select DIP-switch setting #7 and enable DP1 via
SW3 of switch S2. Apply 4mA and adjust R3 so the display reads ".0000".
Apply 12mA and adjust R7 so the display reads ".2500".
