This section of the manual contains maintenanceinformation or use n preventivemaintenance,orrectivemaintenance,r troubleshooting f the 214.

PREVENTIVE AINTENANCE

General

Preventivemaintenanceconsists of cleaning, visual

inspection, lubrication, etc. When performed on aregularbasis,preventivemaintenance an prevent nstru-ment breakdownan d may improve he reliabilityof thisinstrument. Th e severity of environment o which th e214 is subjectedwill determine he frequency of main-tenance. A convenient time to perform preventivemaintenances preceding ecalibration f the instrument.

Avoid the use of chemical cleaning agents whichmight damage the plastics used in this instrument.Avoid chemicals which contain hydrochloric acid,

sodium hydroxide, or sulfuric acid.

Cleaning

The 214 should be cleaned as often as operatingconditions equire.Accumulation f dirt in the nstrumentcan cause omponentbreakdown.

The high-impact lasticcovers rovideprotectionagainstdust in the interior of the instrument.Loosedustaccumu-lated on thesecovers an be removedwith a soft cloth orsmallbrush.Th e brush s alsouseful or dislodging irt onand around he exteriorcontrols.Dirt that remains an beremovedwith a soft cloth dampened n a mild detergent

and watersolution.Abrasive leaners houldnot be used.

Cleaninghe interiorshouldonly be occasionally eces-sary.The bestway to clean he interior is to blow off theaccumulated ust with dry, low-velocityair. A soft-bristlebrushor a cotton-tippedapplicator s useful or eleaningnnarrowspaces r fo r cleaningmoredelicate omponents.

Lubrication

Generally, here are no components n the 21 4 tharequire lubrication. No lubrication should be used othe contacts or rotary parts of the rotary switches. Threliability of potentiometers hat are not permanensealedcan be maintainedby lubricationwith a lubricathat does not affect electrical characteristics(e.Tektronix Part No. 006-2574-00).Do not over-lubrica

Visual nspection

The 214 should be inspectedoccasionally or sudefects as broken connections, mproperly seated ranstors, damaged ircuit boards,and heatdamaged arts.Thcorrectiveprocedure or most visibledefects s apparehowever, particular care must be taken if heatdamagcomponents re found. Overheating sually ndicates thtrouble in the instrument; herefore, orrectinghe causethe overheating s important to preventrecurrence f thdamage.

CRT CareTo prolong the useful life of the Storagescreen, h

following precautions hould be observedwhen operatithis nstrument:

1. Care must be taken in the degreeof writing-beaintensity that is used,particularlywhen usingslow sweerates,X-Y displays,or the STORE mode. Too-highbeaintensitymay permanently amagehe CRT screen.

2. Avoid repeated seof the sameareaof the screena particulardisplay is beingStoredrepeatedly, hange h

Troubleshooting Equipment

Th e malority of troubleshooting o be done on th214 can be accomplishedwith a 20,000 ohms/volt VOMsuch as a Triplett Model 630-NA or a SimpsonMod262. Use a dynamic transistor estersuchas a TektronType 577 Transistor-Curve racer to check the semconductor devicesused in the 214. To check waveformin thid instrument,use a test oscilloscope ith a DC t500 kilohertz frequency response nd one millivolt t50 volt/division eflection actor.

1. Install a 270 otnrs reslstor for R388, turn the 214 on , se t SEc/DIv to .5 s,

and set IMENSITY to maximum (fully c1ocl,:wlse).

2. The traces !.ril-l- shorr as dots. Set CH I POS to place the CH I dot to the tophorlzontal graticule llne and set CH 2 POS to place the CH 2 dot to the bot-tom horizontal gratlcule Line.

3. Check that no more than 1.5 divisions of unblanked trace extends vertlcallyf rorn each dot.

4. If each unblanked trace exceeds 1.5 vertlcal divisions, turn off the 214'lnstall the next larger size for R388, recheck and.repeat steps 2 through4 until unblanked traces are no more than 1.5 diviolons high whlle main-taini.ng mlnimum lntenslty change when svrltching sweep speed from 5 ms to
