6.5. RATIO 1:1
6.5.1. Model 9330 /100 M
to Model 9330 /100 M
Step 1. Set up the 6675A in High Ohms measurement mode. Do not emerse the
two resistors in oil. Attach the 100 M Standard Resistor to Rs and the
Resistance Transfer Standard configured as 100 M to Rx
Step 2. Set test voltage = 990 Volts
Step 3. Set reversal rate = 120 seconds
Step 4. Start measurement and record ratio =
R
a
Step 5. Interchange resistors and repeat test
Step6. Record ratio=
