PrecautionstoObserveBeforeUsingtheHT-5200
・ Besuretoreadthisinstructionmanual.
ToensurethatyougetthemostoutoftheHT-5200,andoper-
ateitsafely,besuretoreadthisinstructionmanual.
・ Avoidsuddenchangesintemperature.
AvoidbringingtheHT-5200suddenlyfromahotlocationinto
acoolone,orviceversa,asthiscancauseinternalcondensa-
tionwhichcanleadtofailures.
・ Takecarethatwateranddustarenotallowedtoenter
theinsideoftheHT-5200.
AvoidusingtheHT-5200inlocationsthatwouldsubjectitto
excessivedust,water,andhighhumidity.
・ DonotdroptheHT-5200orotherwisesubjectitto
shock.
TheHT-5200containsprecisionelectronicscomponents.Do
notdropit,andavoidsubjectionittosevereshock.
・ Takecarethatthelensofthelightprojector-receiver
isnotdamaged.
Damagetothislenswillcausealossofperformance.
・ WipedirtfromtheHT-5200usingeitheradryclothor
onemoistenedjustslightly(wetandwrungoutwell)
withaneutraldetergent.
Neverwipedirtoffusingthinners,benzene,orothervolatile
liquidsoralcohol.
・ IftheHT-5200istobeleftunusedforalongtime,re-
moveitsbatteries.
Removebatteriestopreventdamagefromfluidleakingfrom
wornbatteries.
・ Donotapplyanyvoltagestothepluseoutputcon-
nector.
・ NeveruseanyACadaptorotherthanthePB-703(op-
tion).

WARNING
SAFETYPRECAUTIONS
・ WhenusinganACadaptorortheAX-1200pulseoutputcable,
takecarethatthecabledoesnotbecometangledaroundthe
rotatingbody,asthiscanbeextremelydangerous.
・ Whenusingacontactadaptortightenthemountingscrewse-
curelybyhandtoholditsecurelytotheHT-5200.
・ Whenusingacontactadaptortomakerpmmeasurements,be
extremelycarefulwithsafetyprecautions.
Particularcareisrequiredinmakingmeasurementsover10,000
r/min.Whenusingthecircumferentialringtomeasuretan-
gentialspeed,takecarewithmeasurementsathighspeed.(For
details,refertopage29.)
・ Thecontacttipandcircumferentialringareexpendableitems
thatwear.Measurementwithacontacttiporcircumferential
ringwhichhasbecomedeformedorhascrackedisextremely
dangerous.Replacesuchitemswithnewones.
・ Itisdangeroustouseacrackedcontactadaptor.Replacesuch

5. MEASUREMENTPREPARATION
5.1 Non-ContactMeasurements
① WhenusingtheHT-5200forthefirsttime,installbatteries.
(Thisappliestocontacttypemeasurementsaswell.)
② Applyareflectivemarktotherotatingbodytobemeasured.
(RefertoSection9:PrecautionsforNon-ContactMeasure-
mentsfordetailsonapplyingthereflectivemark.)
A) Cleananyoil,water,anddustoffofthesurfacetowhich
thereflectivemarkistobeapplied,andapplythemarkto
aflatpartofthesurface.
B) Ifthesurfacetowhichthemarkisappliedisshiny(e.g.,a
platedsurface),eithermakemeasurementsatananglere-
movedfromtheperpendiculartothissurface,orpaintthe
surfaceblackbeforeapplyingthereflectivemark.
③ Pressthepowerswitchandshinethelightfromthelightpro-
jector-receiver(detectionsection)ontothemark,verifyingthat
theinputsignalindicatorlampflashes.(Athighrpm,thelamp
willappeartobelightedcontinuously.)
A) Toensureproperdata,makeeachmeasurementforatleast
3seconds.
B) Maintainaproperdistancebetweenthereflectivemarkand
thedetectionsectionoftheHT-5200.(RefertoSection9:
PrecautionsforNon-ContactMeasurementsfordetailson

holeoftheHT-5200,andtightenthescrewoftheadaptorse-
curelyintothethreadedtripodmountingholeoftheHT-5200.
(Theprotrusionoftheadaptorissensedintheguideholeto
automaticallyswitchtheHT-5200fromnon-contactmeasure-
menttocontactmeasurement.)
② TurnthepoweroftheHT-5200on,androtatethedetection
shafttoverifythatthedisplaycomeson.
③ MounttheKS-300ContactTip,andusetheUNITswitchto
selectthemeasurementunits(r/min,r/s,orms).
④ Pressthecontacttipupagainsttherotatingshafttobemea-

centeroftheshaftend.Whendoingthis,
holdtheHT-5200so
thatitsaxisisparallelwiththatoftheshaftbeingmeasured.
A) DonotattempttousetheHT-5200withshaftsnothaving
acountersunkdepressionattheend.
B) Measurementerrormayoccur,dependinguponthemate-
