Calibration 2-7
6. Using the edit keys, adjust the display to agree with the new DMM voltage reading, then
press ENTER. The unit will then will then prompt for DVM full-scale calibration:
FULL SCALE DVM
ALL READY TO DO?
7. Press ENTER to complete DVM full-scale calibration.
8. Connect the digital multimeter volts input and characterized 4
Ω
resistor to the Model
2303 OUTPUT SOURCE terminals, as shown in Figure 2-3. Be sure to observe proper
polarity (SOURCE + to DMM INPUT HI; SOURCE - to INPUT LO).
9. Be sure the digital multimeter DC volts function and auto-ranging are still selected.

Connections for 5A current calibration
10. At this point, the unit will prompt for 5A full-scale calibration output:
SOURCE 5 AMPS
SET 1.90000 A
11. Using the edit keys, adjust the set value to 1.9000A, then press ENTER. The unit will
then prompt you for the DMM reading, which calibrates the 5A current limit:
SOURCE 5 AMPS
READ1 1.90000 A
12. Note the DMM voltage reading, then calculate the current from that reading and the
actual 4
Ω
resistance value: I = V/R. Adjust the Model 2303 current display value to agree
with the calculated current value, and press ENTER.
