Measuring LOW-LOSS CAPACITOR Calibration Data

The LOW-LOSS CAPACITOR calibration should be performed for high Q (or low D:
dissipation factor) measurements at high frequencies. The LOW-LOSS CAPACITOR
calibration allows high accuracy for phase measurements. This calibration can be skipped
if you do not need it for your purposes.
Step 1. As shown in Figure 3-38, turn the LOW-LOSS CAPACITOR clockwise with the provided
torque wrench to connect it securely to the 7-mm terminal.
CAUTION
Do not turn the nob of the LOW-LOSS CAPACITOR. Lightly hold the nob to prevent the
inner coaxial electrodes from moving when turning the outer connector nut of the
LOW-LOSS CAPATITOR.
