  • Page 14: Notes On Safety

    Notes on Safety R&S RT-ZC30 Notes on Safety Thank you for purchasing the R&S RT-ZC30 current probe. To obtain maximum performance from the device, please read this manual first, and keep it handy for future reference. Risk of physical injury This device is designed to comply with IEC 61010 Safety Standards, and has been thoroughly tested for safety before shipment.
  • Page 15 ® Notes on Safety R&S RT-ZC30 Risk of fatal injury ● To avoid electric shock, do not remove the device's cover. The internal components of the device carry high voltages and may become very hot during operation. ● To avoid electric shock and short circuits, never attach the clamp to bare, unisolated conductors.
  • Page 16 ® Notes on Safety R&S RT-ZC30 Risk of fatal injury ● This device is made for use with the R&S RT-ZA13 probe power supply. ● When using a measurement instrument that does not provide isolation between its input terminals and chassis or other input terminals, please pay attention to the following points.
  • Page 17 ® Notes on Safety R&S RT-ZC30 Risk of instrument damage ● To avoid damage to the device, protect it from vibration or shock during transport and handling, and be especially careful to avoid dropping. ● To avoid damage to the device, do not place the device on an unstable table or an inclined place.
  • Page 18 ® Notes on Safety R&S RT-ZC30 ● Keep the sensor head closed when not in use, to avoid accumulating dust or dirt on the mating core surfaces, which could interfere with clamp performance. ● Avoid stepping on or pinching the cable, which could damage the cable insulation.

  • Page 19: Product Description

    Product Description Product Overview The R&S RT-ZC30 is an AC/DC current probe. It allows the user to make current measurements from DC to 120 MHz. By clamping on the conductor to be mea- sured, the current waveform is captured easily without interrupting the electric cir- cuit.

  • Page 27 ® Measuring Procedure R&S RT-ZC30 Preparing the Measurement Risk of instrument damage ● Check that the conductor being measured is not clamped when supply- ing power to the device. A demagnetizing waveform may be generated when power is supplied, causing damage to components connected to the circuit being measured.

  • Page 28: Demagnetizing And Zero Adjustment

    Demagnetizing and Zero Adjustment Risk of circuit damage ● Do not demagnetize while the R&S RT-ZC30 is clamping a conductor to be measured. Demagnetizing causes current to flow into the conductor, which may damage parts in the circuit to be measured.

  • Page 29: Connecting The Probe To The Dut

    ® Measuring Procedure R&S RT-ZC30 Connecting the Probe to the DUT Risk of instrument damage When opening the sensor head, always operate the opening lever. Subject- ing the sensor head to force from the directions shown in the figure while it is locked may damage the clamping mechanism.
  • Page 30 ® Measuring Procedure R&S RT-ZC30 Connecting the Probe to the DUT If the sensor head is not properly closed, accurate measurement is not possi- ble. ● To measure DC or low-frequency current, multiple windings may be used to increase relative sensitivity (10 windings multiplies the mea- sured current by a factor of 10).
  • Page 31 ® Measuring Procedure R&S RT-ZC30 Connecting the Probe to the DUT Risk of instrument damage due to continuous input current ● The maximum continuous input range is based on heat that is internally generated during measurement. Always keep the input current below this level.
  • Page 32 ® Measuring Procedure R&S RT-ZC30 Connecting the Probe to the DUT Risk of instrument damage due to continuous input current ● At high ambient temperatures, the built-in safety circuit may activate at current input levels below the rated continuous maximum current.
  • Page 33 ® Measuring Procedure R&S RT-ZC30 Connecting the Probe to the DUT ● Immediately after powering on, this device may be subject to an appre- ciable offset drift due to the effect of self-heating. To counteract this, allow the device to warm up for about 30 minutes before carrying out measurements.

  • Page 34: Disconnecting The Probe From The Dut

    ® Measuring Procedure R&S RT-ZC30 Disconnecting the Probe from the DUT At high frequencies, common mode noise may affect measurements taken on the high voltage side of circuits. If this occurs, reduce the frequency range of the waveform measuring instrument, or clamp onto the low-voltage side of the circuit, as appropriate.

  • Page 35: Troubleshooting

    ® Measuring Procedure R&S RT-ZC30 Troubleshooting Risk of instrument damage ● To prevent wire breaks, do not pull on the cord to disconnect the output connector from the waveform measurement instrument. Always grip the terminator and pull the unlock lever toward you before disconnecting the connector.
