I am using for testing the quality of brand new battery chargers a battery simulator from Amperis, with this set the charger can inject up to 200 A. I wonder if someone knows a battery simulator that can be injected more current, since the Amperis battery simulator is not prepared for beeing...
Since the voltage drop is the ohmic resistance times the current you may choose to meter the electric resistance. For low resistance measurement the best way is to use the 4-wire method or an ohmmeter that meters that way. This link may be helpful to you...
I completely agree with John Snell. The emissivity tables that you can find in hundreds of places, sometimes even in the internal memory of the infrared camaras, are not reliable. If you need accuracy you better measure the temperature with a contact thermometer and adjust the emissivity in the...
