Section 17: Calibration Model 6482 Dual-Channel Picoammeter / Voltage Source Reference Manual
Step 6. Channel 1 current calibration adjustment
Follow these steps to calibrate channel 1 current measurements. Table 17-14 summarizes
channel calibration currents and commands.
1. Connect the Model 6430 to the Model 6482 channel 1 INPUT connector, as shown in
Figure 17-9.
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 1, 2 nA range:
:SENS1:CURR:RANG 2e-9
4. Send the following command to calibrate the positive full-range current point:
:CAL:PROT:SENS1 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:SENS1 0
7. Set the Model 6430 current to -1.90000 nA.
