Relay Contact Resistance Measurement in Mili Volt.

A relay having 8 N/O and 8 N/C contact . We have to pusses 100mA Current through the contact and measure the contact resistance of the relay in mV(e.g 3.25mV or 4.30mV etc,when contact position). It will show in a 16X4 line LCD . at a time 8 will show in the 1st & 2nd line that is N/O, 3rd & 4th that is N/C. Display as well as 8+8 pcs Dual color(G-R) Led should be connected. when in the permissible range(programmable by user) the led shows Green,beyond range is Red.Also display (1st line A1, 2nd line 3.98V). Or (1st line A1, 2nd line 4.10V). A1 and voltage reading will blink as user programmed upto 4 volt range.also Red led glow.
