Compliance Current Accuracy - Keithley 2302 Instruction Manual

Compliance current accuracy

Follow the steps below to verify that Model 2306/2306-VS/2306-PJ compliance current
accuracy is within specified limits. The test involves setting the compliance current to specific
values and determining the actual current by measuring the voltages across a characterized 1Ω
resistor with a precision digital multimeter.

With the power supply's output off, connect the digital multimeter and characterized 1Ω
resistor to the Model 2306 OUTPUT #1 SOURCE terminals, as shown in
Be sure to observe proper polarity (SOURCE + to INPUT HI; SOURCE - to INPUT
LO). Be sure to use 4-wire connections to the resistor terminals.
