Note: TL_BIAS = Vdd /2
The differential input of the resistor networks is:
= (V1 - V2) / (K+1)
where K=1M / 34.8k = 28.74.
The resistor network successfully divides the input by a ratio of (28.74+1) = 29.74.

Voltmeter provides resolution to 0.00006V for a source between
-30V to +30V.
It also displays the Thermocouple voltage
For connecting target voltage measurement
The short type K thermocouple is connected to P2 and P3 to
provide the current for temperature sensing.
The button (CSB1) selects the voltage source between the volt-
meter and the thermocouple. The voltage of the selected
source will be displayed on the LCD and on the PC.
LED D1 indicates Voltmeter is selected.
LED D2 indicates thermocouple is selected.
The kit can be powered by one AA battery.
To connect to PC or dual cell AA battery pack for power.
Allow programming, trace, and debug.
