Calibration 19-19
4. From the calibration menu, select GAIN, then press ENTER. The instrument will
prompt you for Remote PreAmp gain calibration:
PREAMP GAIN CAL
10uA 1uA 100nA 10nA 1nA
100pA 10pA 1pA
5. Select the 100nA range, then press ENTER. The unit will prompt you as follows:
I-CAL
Press ENTER to Output +000.00nA
6. Press ENTER. The unit will prompt you for calculated current:
DMM RDG: +000.0000nA
Use , ▲, ▼, , ENTER or EXIT.
7. Note the DMM voltage reading, then calculate the current from the voltage reading and
the actual characterized calibration standard resistance value: I = V/R. Adjust the Model
6430 display to agree with the calculated current value, then press ENTER.
8. The unit will prompt you as follows:
I-CAL
Press ENTER to Output +085.00nA
