Step 5. Interchange resistors and repeat test
Step 6. Record ratio = R
b
Unit under test passes when:
6.4. RATIO 10:1
6.4.1. Model 9330 /10 k
 to Model 9350 /(100 k Configuration)
Step 1. Set up the 6675A in Normal Ohms measurement mode with the two
resistors in a temperature controlled oil bath. Attach the 10 k Standard
Resistor to Rs and the Resistance Transfer Standard configured as 100 k
to Rx
Step 2. Set test current = 0.10 mA
Step 4. Set reversal rate = 120 seconds
Step 5. Start measurement and record ratio = R

6.4.2. Model 9350 /(1K  Configuration) to Model 9330 /10 k
Step 1. Set up the 6675A in Normal Ohms measurement mode with the two
resistors in a temperature controlled oil bath. Attach the Resistance
Transfer Standard configured as 1k  to Rs and the 10 k Standard
Resistor to Rx
Step 2. Set test current = 0.316 mA
Step 4. Set reversal rate = 60 seconds
Step 5. Start measurement and record ratio = R
