Keithley 6430 User Manual

18-30 Performance Verification
4. Verify ohms measurement accuracy for each of the resistance values listed in
Table 18-15. For each measurement:
• Connect the BNC shorting cap to select the appropriate resistance value.
• Select the appropriate ohms measurement range with the RANGE keys.
• Verify that the Model 6430 resistance reading is within the limits given in the
table.
2TΩ and 20TΩ range accuracy
1. With the power off, connect the characterized 1TΩ resistor directly to the Remote
PreAmp IN/OUT HIGH jack as shown in Figure 18-10. (Use a male triax-to-triax
adapter.)
