NOTES
• Theabsolute sparkplug voltage readingwill dependon theposition of thepick-up,
theparticularcharacteristicsofthewire,etc..Thereforetheplacementofthepick-up
relativetothewireshouldbekeepasconsistentaspossibleforallthemeasurements
inordertocomparevoltagereadingsbetweenseveralcylinders’sparkplugwires.
•Sparkburntime,dwellangleandRPMmeasurementsarenotsensitivetotheexact
positionofthepick-uprelativetothesparkplugwire,butthepick-upmustbepositioned
sotheinstrumentiscapableofdetectingthesignal.
• When several spark plug wires are routed or bunched close together, the
capacitivepick-upmayreceivesignalsfromtwoormorewiressimultaneously,which
couldcauseerroneousmeasurements.Inthesesituationsitisnecessarytoseparate
thewireundermeasurementfromtheothers,inordertoreduceinterferenceandobtain
anaccuratemeasurement.
8. RECHARGING THE INSTRUMENT
1-Ifstilloperating,turntheinstrumentpoweroff.
2-Locateandlifttherubbercap(attachedtotheprotectiveholsterandlocatedbesides
theBNCconnector)torevealthemicroUSBreceptacle.

3-InserttheUSBchargercable’smicroUSBplugintothereceptacleoftheinstrument
matchingtheorientationoftheconnectors.
4-InserttheUSBtypeAconnectorofthecableintotheUSBportofthesuppliedUSB
powerchargeradapter,andplugthepoweradapterintoanACpoweroutlet.
5-Uponstartofchargingthebattery,thedisplaywillshowthecharginginprogressicon
andthescreenwillturnoffafterafewseconds.
