2-8 Calibration
13. The Model 2303 will then prompt for another DMM reading, which is used for 5A mea-
surement calibration:
SOURCE 5 AMPS
READ2 1.90000 A
14. Again, calculate the current from the new DMM reading and 4
Ω
resistor value. Adjust
the 2303 current display reading to agree with the new current, then press ENTER.
15. Disconnect the 4
Ω
resistor, then connect the 3k
Ω
resistor in its place. (See Figure 2-4.)

Connections for 5mA 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 5mA for 5mA range full-scale
calibration:
SOURCE 5 mA
ALL READY TO DO?
18. Press ENTER to output approximately 5mA. The unit will then prompt you for the
DMM reading:
SOURCE 5 mA
READ1 4.50000 mA
