WARNING
• Themaximuminputvoltageforisolatedinputismorestrictlylimitedthanfornon-isolated
input.Thisisduetothefactthat,unlikenon-isolatedinputinwhichGNDisprotectedby
aprotectivegroundingpotential,theGNDforisolatedinputisfloating(insulated),soany
protection via protective grounding is disabled.
• Whenusingthisprobeforisolatedinput,youmustuseitwith42Vorlessforboththe
HandLsides.Inparticular,theGNDshellhasexposedmetalsothereisahighriskof
electricshock.EvenwhenahighpotentialonlyexistsontheHside,highvoltagecanstill
occurontheLsidecreatingaverydangerouscondition.
• Evenwhenthevoltageofthenon-isolatedinputiswithinthemaximum,toensurethat
currentflowstotheprotectivegroundingcircuittheprotectivegrounding(fromthepower
supply’s3-prongterminal)ofthemainunitmustbeenabled,andforplug-inmodules,the
module attachement screws must be securely fastened.
• Thisprobehasa10:1-1:1switch.Besuretoheedthefollowingcautionswhenswitching
the probe.
• Confirmtheoscilloscope’smaximuminputvoltagewhenswitchingtheprobeto1:1.
Accidentallyintroducingexcessiveinputcandamagetheinputsection.
• Donotswitchtheprobewhilevoltageisbeinginput.Thisisextremelyhazardous.
