Handling the probe Connecting the probe Handling the probe The R&S RT-ZC30 can withstand a moderate amount of physical and electrical stress. To avoid damage, treat the probe with care: ● Prevent the probe from receiving mechanical shock. ● Avoid strain on the probe cable and route it carefully. Keep the cable away from heat sources, as bare conductors could be exposed if the insulation melts.
Turn off the power switch at the rear of the R&S RT-ZA13 probe power supply. 3. Connect the power cord. 4. Connect the power plug of the R&S RT-ZC30 to the power receptacle of the R&S RT-ZA13 probe power supply.
Setting up and demagnetizing 1. With the waveform measuring instrument input at ground, adjust the waveform to the zero position. 2. Connect the R&S RT-ZC30 current probe to the power supply as described in Chapter 3.2, "Connecting the probe to the power supply", on page 16.
4. NOTICE! Risk of circuit damage. Demagnetizing causes current to flow into the conductor, which may damage parts in the circuit to be measured. Do not demagnetize while the R&S RT-ZC30 is clamping a conductor to be mea- sured. Make sure that there is no conductor in the sensor aperture.

® Connecting the probe R&S RT-ZC30 Connecting the probe to the DUT 3. Align the sensor so that the current direction indication matches the direction of current flow through the conductor that you measure. The conductor should be in the center of the clamp aperture because the measurement may be affected by the position within the clamp aperture of the conductor being mea- sured.
® Connecting the probe R&S RT-ZC30 Considerations for measurements Disconnecting the probe from the DUT Once measurement has completed: 1. Pull the opening lever toward you. Remove the device from the conductor that you measure. 2. Disconnect the terminator from the waveform measurement instrument.

® Connecting the probe R&S RT-ZC30 Considerations for measurements Continuous input of current exceeding the rated maximum or repeated activa- tion of the safety function may result in damage to the device. ● Even if the input current does not exceed the rated continuous maximum cur- rent, continuous input for an extended period of time may result in activation of the safety circuit to prevent damage resulting from heating of the sensor.

® Connecting the probe R&S RT-ZC30 Considerations for measurements ● Acoustic resonance can occur depending on the amplitude and frequency of the measured current. This sound may also occur during demagnetizing oper- ation, but it is not a malfunction or probe failure.
