Page 5: Notes On Safety
® Notes on Safety R&S RT-ZC20 Notes on Safety Thank you for purchasing the R&S RT-ZC20 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 6 ® Notes on Safety R&S RT-ZC20 Risk of fatal injury ● To avoid electric shock and short circuits, never attach the clamp to bare, unisolated conductors. Make sure to measure at a location on an insulated wire where the insu- lation is sufficient for the circuit voltage.
- Page 7 ® Notes on Safety R&S RT-ZC20 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 8 ® Notes on Safety R&S RT-ZC20 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. ● This device should be installed and operated indoors only, between 0°C and 40°C (32°F to 104°F) and 80% RH or less.
- Page 9 ® Notes on Safety R&S RT-ZC20 ● To avoid damaging the sensor cable and power supply cable, do not bend or pull the cables. ● Avoid stepping on or pinching the cable, which could damage the cable insulation. ● Keep the cable well away from heat sources, as bare conductors could be exposed if the insulation melts.

Page 10: Product Description
® Product Description R&S RT-ZC20 Inspecting the Contents Product Description Product Overview The R&S RT-ZC20 is an AC/DC current probe. It allows the user to make current measurements from DC to 100 MHz. By clamping on the conductor to be mea- sured, the current waveform is captured easily without interrupting the electric cir- cuit. -

Page 13: Putting Into Operation
® Putting into Operation R&S RT-ZC20 Preparing the Measurement Putting into Operation Preparing the Measurement Voltage check When using a different power supply than the R&S RT-ZA13 probe power supply, before turning on the power, make sure that the voltage of the used power supply matches the supply voltage indicated in the data sheet "R&S RT-Zxx high voltage and current probes". - Page 14 ® Putting into Operation R&S RT-ZC20 Preparing the Measurement 4. Check that the conductor being measured is not clamped when supplying power to the R&S RT-ZC20. When power is turned on, a demagnetizing wave- form is initially applied to the output. This is intentional in the design, and not a fault.

Page 16: Demagnetizing And Zero Adjustment
® Putting into Operation R&S RT-ZC20 Demagnetizing and Zero Adjustment Demagnetizing and Zero Adjustment Risk of circuit damage ● Do not demagnetize while the R&S RT-ZC20 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. -

® Putting into Operation R&S RT-ZC20 Connecting the Probe to the DUT 7. If zero adjustment is not possible, turn the coarse adjustment trimmer to bring the trace within the range of adjustment by the zero adjustment dial, see Chapter 2.4, "Description of the Probe", on page 11. - Page 18 ® Putting into Operation R&S RT-ZC20 Connecting the Probe to the DUT 4. Press the opening lever until the UNLOCK indication disappears. Make sure that the sensor head is properly closed. If the sensor head is not properly closed, accurate measurement is not possi- ble.
- Page 19 ® Putting into Operation R&S RT-ZC20 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 20 ® Putting into Operation R&S RT-ZC20 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 21 ® Putting into Operation R&S RT-ZC20 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 22 ® Putting into Operation R&S RT-ZC20 Connecting the Probe to 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.
