- Page 1 User Manual XFVP Medium Voltage Fiber Isolated Voltage Probe Revision 5 www.saker-mv.com BR-XFVP-Rev 5.
- Page 2 DIMENSIONS INTRODUCTION The XFVP probe is a novel voltage probe that provides high voltage isolation via fiber optic cables. Not only is this approach advantageous from the voltage isolation point of view, but is also immune to typical radiated interferences and capacitances created when using long coaxial measuring cables.
- Page 3 It is always recommended that the probe head be installed over a tripod mount and secured When manually positioning the probe head keep in mind the unit is physically joined to the receiver unit, moving the probe head may send the receiver into the floor www.saker-mv.com BR-XFVP-Rev 5.

- Page 5 External patch cables that interface the user system with the SMB connector can be made by the user. Saker recommends the use of good quality SMB connectors, for example reference R114082000 from Radiall. Please read the accessories PDF to find more about these. The unterminated SMB cable leaves freedom of choice for the user to make additional terminations.
- Page 6 Set the oscilloscope vertical scale at an appropriate scale given the conversion ratio of the Ω XFVP and attenuator (see specifications section) in question. A 50 termination is necessary for calibration to take place successfully.

Take measurements as needed. During interpretation of results or during adjustments to the DUT place the probe in standby again.

- Page 10 It is advisable to install a voltage detector/indicator on the measured line that provides visual and clear indication about the presence of potentially dangerous voltages. SAKER offers the MVD and MVDZ series of medium voltage presence detectors. LOW BATTERY CONDITION The probe head will measure the voltage of the batteries to warn the user in case of a low battery condition.

- Page 12 PERFORMANCE VERIFICATION XFVP probes are shipped from Saker and both probe head and receiver are tested as a system and adjusted to meet the DC gain, offset and frequency specifications. Accuracy is automatically maintained by two internal precision voltage references and a software algorithm so there is no provision for manual user adjustment.
