Section 17: Calibration
9. Repeat steps 3 through 8 for the 20 nA to 2 μA ranges using
to:
•
•
10. Connect the Model 5700A to the Model 6482 channel 2 INPUT connector, as shown in
Figure
11. Select the Model 5700A V/R amperes function and set the output current to 1.90000 μA, and
then turn on the Model 5700A output.
12. Send the following command to select the channel 2, 20 μA range:
:SENS2:CURR:RANG 2e-5
13. 13. Send the following command to calibrate the positive full-range current point:
:CAL:PROT:SENS2 1.9e-5
14. Set the Model 5700A current output to 0 μA.
15. Send the following command to calibrate the zero current point:
:CAL:PROT:SENS2 0
16. Set the Model 5700A current to -19.0000 μA.
17. Send the following command to calibrate the negative full-range current point:
:CAL:PROT:SENS2 -1.9e-5
18. Repeat steps 11 through 17 for the 200 μA to 20 mA ranges using
sure to:
•
•
Step 8. Program calibration dates
Use following commands to set the calibration date and calibration due date:
:CAL:PROT:DATE <yyyy>, <mm>, <dd>
:CAL:PROT:NDUE <yyyy>, <mm>, <dd>
Note that the year, month, and date must be separated by commas.
Step 9. Save calibration constants
Calibration is now complete, so you can store the calibration constants in EEROM by sending the
following command:
:CAL:PROT:SAVE
NOTE
Step 10. Lock out calibration
To lock out further calibration, send the following command after completing the calibration
procedure:
:CAL:PROT:LOCK
17-38
Select the appropriate range using the :SENS2:CURR:RANG <Range> command.
Send the appropriate calibration current values with the :CAL:PROT:SENS1 <Current>
command.
17-10.
Select the appropriate range using the :SENS2:CURR:RANG <Range> command.
Send the appropriate calibration current values with the :CAL:PROT:SENS2 <Current>
command.
Calibration will be temporary unless you send the SAVE command.
