Figure 6-10 How to connect load standard
Step 3. Click the LOAD button in the calibration window and measure the load calibration data.
Step 4. Turn the connector nut outside the load standard counterclockwise as viewed from the top
and remove the load standard from the 7-mm terminal.
8. How to measure DC open/short/load calibration data
To use the dedicated open/short/load standard to measure DC resistance (Rdc), execute
additional DC open/short/load calibration as follows:
Step 1. Connect the DC open standard to the 7-mm connector on the test head.
Step 2. Click the DC OPEN button in the calibration window and measure the open calibration
data.
Step 3. Remove the DC open standard and connect the DC short standard in its place.
Step 4. Click the DC SHORT button in the calibration window and measure the short calibration
data.
Step 5. Remove the DC short standard and connect the DC load standard in its place.
Step 6. Click the DC LOAD button in the calibration window and measure the DC load calibration
data.
Step 7. Remove the DC load standard from the 7-mm terminal.
9. How to measure low-loss capacitor calibration data
Step 1. Firmly connect the low-loss capacitor to the 7-mm terminal on the test head by turning the
connector nut clockwise as viewed from the top (
Figure 6-11).
CAUTION Do not turn the knob of the LOW-LOSS CAPACITOR. Lightly hold the knob to prevent
the inner coaxial electrodes from moving when turning the outer connector nut of the
LOW-LOSS CAPACITOR.
