Section 17: Calibration
8. Send the following command to calibrate the negative full-range current point:
:CAL:PROT:SENS1 -1.9e-9
9. Repeat steps 3 through 8 for the 20 nA to 2
μ
A ranges using
to:
•
Select the appropriate range using the :SENS1:CURR:RANG <Range> command.
•
Send the appropriate calibration current values with the :CAL:PROT:SENS1 <Current>
command.
10. Connect the Model 5700A to the Model 6482 channel 1 INPUT connector, as shown in
.
11. Select the Model 5700A V/R amperes function and set the output current to 1.90000
μ
A, and
then turn on the Model 5700A output.
12. Send the following command to select the channel 1, 20
μ
A range:
:SENS1:CURR:RANG 2e-5
13. Send the following command to calibrate the positive full-range current point:
:CAL:PROT:SENS1 1.9e-5
14. Set the Model 5700A current output to 0
μ
A.
15. Send the following command to calibrate the zero current point:
:CAL:PROT:SENS1 0
16. Set the Model 5700A current to -19.0000
μ
A.
17. Send the following command to calibrate the negative full-range current point:
:CAL:PROT:SENS1 -1.9e-5
18. Repeat steps 11 through 17 for the 200
μ
A to 20 mA ranges using
as a guide. Be
sure to:
•
Select the appropriate range using the :SENS1:CURR:RANG <Range> command.
•
Send the appropriate calibration current values with the :CAL:PROT:SENS1 <Current>
command.
Step 7. Channel 2 current calibration adjustment
Follow these steps to calibrate channel 2 current measurements.
summarizes channel
calibration currents and commands.
1. Connect the Model 6430 to the Model 6482 INPUT channel 2 connector, as shown in
2. Select the Model 6430 V/R amperes function and set the output current to 1.90000 nA, and
then turn on the Model 6430 output.
3. Send the following command to select the channel 2, 2 nA range:
:SENS2:CURR:RANG 2e-9
4. Send the following command to calibrate the positive full-range current point:
:CAL:PROT:SENS2 1.9e-9
5. Set the Model 6430 current output to 0 nA.
6. Send the following command to calibrate the zero current point:
:CAL:PROT:SENS2 0
7. Set the Model 6430 current to -1.90000 nA.
8. Send the following command to calibrate the negative full-range current point:
:CAL:PROT:SENS2 -1.9e-9
