SAFETY
Symbol in This lanual
/f\ This symbol indicates where applicablecautionary or other i information istobe found.
Power Source
This equipment operates from a power source that does not apply more than 250V rms
between the supplyconductors or between either supply conductor and ground. A protective
ground connection bywayofthe grounding conductor inthe power cord is essential for
safe operation.
Grounding the Product
This equipment is grounded through the grounding conductor ofthe power cord. To avoid
electrical shock, plug the power cord into a properlywiredreceptaclebeforeconnecting
to the equipment input or output terminals.
Use the Proper Power Cord
Useonly the power cord and connector specified for your product.
Use the Proper Fuse
Toavoid fire hazard, usea fuse ofthe correct type.
Donot Operate in ExpIos i ve Atmospheres
Toavoidexplosion, donot operate this product inan explosive atmosphere.
Donot Remove Cover or Panel
Toavoidpersonal injury, donot remove the cover or panel.Refer servicing to
qualified personnel.
Voltage Conversion
If the power source isnot applied to your product,contact your dealer. To avoid
electrical shock, donot perform the voltageconversion.

2. SAFETY AND EQUIPMENT PROTECTION PRECAUTIONS
1) Check your line voltagebeforeuse.Theoscilloscopehasa fuseholderandvoltage
selector onthe left oftheAC inlet ontherearpanel.Thevoltage below theW lark
shows the1inevoltage setting of your osci1loscope.If your line voltageis
different from theoscilloscope setting, thereisa danger ofmalfunctioning.Do
not connect tothesupply until thevoltageselector matches thesupplyvoltage.
Setto100V.
2)Theosci1loscopeis equipped with internal components thatarehighly charged
electrically. For your ownprotection,donot remove thecasingforanyreason.
3)Donotusetheoscilloscopeinthefollowing locations.
•In direct sunlight
•Inextremelyhot and/or humid areas
•Inareasaffectedbyhigh levels of mechanical vibration
• Around areaswithstrong lines of magnetic forcesor impulse voltage
4) Make surethatthevoltageappliedto each inputterminal does not exceed the maximum
specified.
a CH1 andCH2inputterminals: 500Vp-por250V (DC+ AC peak, 1kHzor less)
^CH3andZ AXIS inputterminals:100Vp-por50V (DC+ AC peak, 1kHzor less)
Donot under anycircumstancesapplyvoltagetothe output terminals from external
power sources.
5)In order topreventtheCRT's fluorescentscreen from scorching,donotadjustthe
brightnesshigherthannecessary.Donotleavethespottingfunctiononforlong
periodsoftime.

6)TheInstrumentIs equipped with auxiliary support. Youcanuseiteither horizontally
or vertically. Donotplaceanyobjectonthetopoftheinstrumentorpositionitin
areas where the ventilation holesinthecasingareblocked.Any blockage wi11
cause the temperature ofthe internal components toincrease, resulting inpossible
damage.
7) Connect a ground wiretotheGNDterminalfor safety.
8)Ifthe power isturnedonandoffrepeatedly,the oscillscope maymalfunction. Once
the power isturnedoff,leave five seconds beforeturningthe power onagain.
9)The probes suppliedwiththeoscilloscopeareprecision parts. Handle them withgreat
care. [The probes suppliedwiththe CS-5230,CS-5260, or CS-5270 have terminalsfor
detecting readout signals. Donotuse them withanosci1loscopewithno probe
detection function. ]

High Sensitivity : Sensitivity upto1 mV/div.
fide Bands : The frequency range isDCto20MHz(-3dB)at
1 fflV and,2 mV/div range andDCto100MHz[DCto
40 MHzforthe CS-5230 or CS-5235, DCto60MHzfor
the CS-5260 or CS-5265] (-3dB) for 5 mV/div.
HDTV : A specially designed HDTV signal triggering circuit
offers stable and adjustment-freesynchronizationwith
the FRAMEand LINE signals from smal1 to large
amplitudes.
Ease of operation: The osci1loscope does notuse multi-function knobs.
Thus, an inexperienced person mayuse it easily.
Straightfowardswitchlayout onthe panel eliminates
errors even for complicated operations.
Three-channel vertical axis : Trigger signals maybe measured onCH3 withoutusing
thetrigger view function.
Stepless sensitivity control: The vertical axis sensitivity maybe changed from 1
mV/div to5 V/div continuouslywith a rotaryswitch.
High Speed Sweep : High speed sweeping is possible ata time base of5
ns/div(during x10MAG operation)
[10ns/div forthe CS-5230 or CS-5235],
High Accuracy:Accuracy is within 3% for both vertical ax i s
sensitivity and sweep time.
Fixed Synchronization: The fixed synchronizationfunctioneliminatestrouble-
some synchronization.
One Touch X-Y : Switching toX-Y operation is via a single switch.
Automatic TriggerSignalSelection: Triggersignal canbe selectedautomaticallyaccording
to the VERT MODE control sett ing by switching the
SOURCE control to VERT.
CHI OUTPUT : A channel 1 output terminal*is added forCHI input
signal monitoring.
High Stability, High Reliability : Hybrid integrated circuits are employed in al 1
circuits, realizing high standards in stabi1ity and
reliability.
Scale Illumination: The scale illumination function makes it possible to
take photographs of waveform datadisplayed ontheCRT
in a dark room.

Delay Time Position :A delay time position maybeset quickly and accu-
rately with coarse and fine controls.
[Thefollowingfeatures apply totheCS-5230,.CS-5280andCS-5270.]
Readout :The verticalaxis input sensitivity, sweep time and
other scalefactors are displayed in characters onthe
CRT.
Cursor Function :The voltage difference,current ratio, time difference,
time ratio, frequency andphase difference maybe
measured with two cursors. Theyare displayed onthe
CRTfor quick and accurate measurement.
