Constant-current sources
CEBO-LC has two accurate built-in current sources (200A / 10A). Both are available on screw terminals.
The exact values of the Fixed Current Outputs are measured during factory calibration process and stored in
flash. You can find more information on how to access calibration data for the Fixed Currend Outputs in
chapter Programming References => C++ => Info.
Application example
To measure a resistor value, connect one terminal of the resistor to the Fixed Current Output and the other to
CEBO-LC GND.
Then, measure the voltage drop across the resistor with one of the Analog Inputs of CEBO-LC. In this
example: AI-0
Because all GND terminals are internally connected, you don't have to wire one GND screw terminal
externally to another one.
The resistor value R is calculated with Ohm's law:
