2-12 Calibration
15. Disconnect the 4Ω resistor, then connect the characterized 30Ω resistor in its place. (See
Figure 2-5.)

Connections for 500mA range calibration
16. Make sure the DMM DC volts function and auto-ranging are still selected.
17. At this point, the unit will prompt to output approximately 500mA for 500mA range full-
scale calibration:
SOURCE 500 mA
ALL READY TO DO?
18. Press ENTER to output approximately 500mA. The unit will then prompt you for the
DMM reading:
SOURCE 500 mA
READ1 450.000 mA
19. Note the DMM voltage reading, then calculate the current from that voltage reading and
actual 30Ω resistance value. Adjust the Model 2303-PJ current display value to agree
with that value, and press ENTER.
