Basic Operations for Magnetic Measurement
STEP 4. Calibration
Step 5. Click the
of the OPEN calibration data measurement, a √ mark appears on the left side of the
Open
NOTE
During calibration data measurement, the message "Wait-Measuring Cal Standard"
appears at the left end of the status bar at the bottom of the screen.
Step 6. Connect the 0 Ω(SHORT) standard to the 7-mm terminal of the test head (see Figure 3-33
on page 63).
Step 7. Click the
of the SHORT calibration data measurement, a √ mark appears on the left side of the
Short
Step 8. Connect the 50 Ω (LOAD) standard to the 7-mm terminal of the test head (see Figure 3-36
on page 64).
Step 9. Click the
of the LOAD calibration data measurement, a √ mark appears on the left side of the
Load
Step 10. Measure LOW-LOSS CAPACITOR calibration data, if necessary. Connect the
LOW-LOSS CAPACITOR to the 7-mm terminal of the test head (see Figure 3-38 on
page 65). Then click the
CAPACITOR calibration data. Upon completion of the LOW-LOSS CAPACITOR
calibration data measurement, a √ mark appears on the left side of the
button.
NOTE
When you measure a low loss magnetic material, measure LOW-LOSS CAPACITOR
calibration data. This allows high accuracy for high Q measurement at high frequencies.
Step 11. Click the
the measured calibration data and save it to the internal memory.
Step 12. Depending on the measurement points of the calibration/fixture compensation data
specified in the
the bottom of the screen will change, as shown in Table 4-4 on page 119.
