Whenconnectingtheprobewithanyinputchannelforthefirsttime,itisrequiredto
maketheadjustment,matchingtheprobewiththeinputchannel.Probewithoutbeing
compensatedandcalibratedwillcausemeasurementerrorormistake.Toadjustprobe
compensation,followthestepsbelow:
1. Settheprobemenuattenuationcoefficientas10×,placetheswitchontheprobeat
10×andconnecttheoscilloscopeprobewithCH1.Connecttheprobeendtothe

5. AutomaticSettingofWaveformDisplay
Theoscilloscopehasautomaticsettingfunction.Accordingtoinputsignals,
automaticallyadjusttheverticaldeflectionfactor,scanningtimebaseandtriggermode
untilthemostappropriatewaveformisdisplayed.Inautomaticsetting,thefrequencyof
themeasuredsignalisrequiredtobe≥50Hzandthedutyratiois>1%.

Applyautomaticsetting
1.Connectmeasuredsignaltosignalinputchannel.
2.PressAUTOkey.Theoscilloscopewillautomaticallysetitsverticaldeflectionfactor,
scanningtimebaseandtriggermode.Iffurthercarefulobservationisrequired,adjustment
canbeconductedagainafterautomaticsettinguntilthewaveformdisplayreachesrequired
