I wouldn't use the 50:1 voltage divider. a THCAD5 with a 5 volt full scale would be more suited to use with it. Instead just calibrate the THCAD to read 200 to 300 volts full scale with a resistor.
I have a Mesa 7i96s card with a THCAD - 10. Do I need a voltage divider for this? I purchased two resistors - 2.4M OHM 1/2W 1% AXIA (
digikey
) as well as a 50:1 voltage divider (
CNCpc
). Do I need both?
