GettingStarted The P5205hasseveral featuresand accessoriesthat make probing andmeasurement a simplertask. Take a moment tofamiliarize yourselfwiththese itemsandtheiruses. Differential Inputs.The inputsare ratedtosafely accept a maximum of1,000V CAT IIbetweeneither RMS input andearthgroundanda maximum difference of 1,300V(DC+ peakAC)betweenthe inputs. NOTE.The input safetyratingsare validforboth attenuationrange settings. However, foruseful measurements, the input shouldbe kept tothe operatinglim

GettingStarted Installation Install the P5205probe asfollows: 1. Connect the output ofthe probe tothe TEKPROBE input ofthe oscilloscope orothermeasurement instrument. The measurement instrument input must have a groundreference. NOTE. Use the 1103 TEKPROBE Powersupply if the instrument does not have the TEKPROBE interface. 2. Select the properrange setting. Forhigherresolutionandless noise whenmeasuringsignalsbelow130V, switchthe attenua- tionto50X. Ifthe overrange indicatorlightsorflashes, the
