3 Operation
1. Connect this probe’s power supply cable to the probe power supply connector on the
YOKOGAWAmeasuringinstrument,700938,or701934.
2. Simply plug-in the BNC output connector to the vertical input of a oscilloscope, and connect the
auxiliary grounding terminal to a proper ground. If necessary, use a ground extention lead. Set
theoscilloscope’sinputresistanceto50Ω.
3. Connect the input to the circuits under measurement.
WARNING
• Toprotectagainstelectricshockthegroundsideoftheoutputcable(theshieldedsideof
the BNC connector) must be grounded.
• Makesuretoavoidanelectricshockwhenconnectingtheprobetotheobjectof

Note
• ConnecttheBNCconnectortotheinputterminaloftheoscilloscopeandfortwopoint
measurement (differential measurement), connect both input leads. Because the performance
declines in case you carry out measurements with only one input lead connected, make sure to
always connect both.
• Accuratemeasurementmaynotbepossiblenearobjectswithstrongelectricfields(suchas

6 This equipment is for measurement category I (CAT I). Do not use it with measurement category II (CAT II),
measurement category III (CAT III), nor measurement category IV (CAT IV).
CAT I applies to electrical equipment on a circuit that is not connected directly to the power source and
measurement performed on such wiring. CAT II applies to electrical equipment that is powered through a fixed
installation such as a wall outlet wired to a distribution board and measurement performed on such wiring. CAT
III applies to measurement of the distribution level, that is, building wiring, fixed installations. CAT IV applies to
measurement of the primary supply level, that is, overhead lines, cable systems, and so on.
7 Pollution degree applies to the degree of adhesion of a solid, liquid, or gas which deteriorates withstand
voltage or surface resistivity. Pollution degree 2 applies to normal indoor atmospheres (with only non-
conductive pollution).
