10. Press the
ENTER
key. The instrument will prompt for the zero current:
I (0)
1
= +0.000000 nA
Use

, ENTER or EXIT.
11. Set the Model 6430 current to 0 nA and press the
ENTER
key. The instrument will prompt for
the negative full-range current:
I(-FS)
1
= -2.000000 nA
Use
,

,
, ENTER or EXIT.
12. Set the Model 6430 current to -1.90000 nA.
13. Adjust the displayed current to match the Model 6430 current, and then press the
ENTER
key
to complete calibration of the present range.
14. Press the
EXIT
key to return to normal display.
15. Repeat steps 3 through 14 for the 20 nA to 2
μ
A ranges, using
as a guide. Be sure
to set the Model 6482 to the correct range using the RANGE
and
keys, and use the
corresponding Model 6430 currents for each range.
16. Connect the Model 5700A to the Model 6482 channel 1 INPUT connector, as shown in
.

MSR1
key, and then set channel 1 to the 20
μ
A current range using the
RANGE
and
keys (the 20
μ
A range has the following format: +00.0000
μ
A).
19. Press the
MENU
key, select
CAL
