DatalogReadings
TheRPM33canloguptoten(10)“readingsets”foreachmeasurementsession(foreachunitof
measuredisplay).Areadingsetconsistsoffour(4)values:
 Initialreading(readingrecordedwhenMEMbuttonispressed)
 Maximumreading(MAXiconshown)
 Minimumreading(MINiconshown)

Averagereading(AVGiconshown)
Thistotals400storedreadings(4valuesperreadingset*10readingsetspermeasurement
session*10unitsofmeasuredisplays)
AmeasurementsessionstartswhentheMEASUREbuttonispressedandendswhenitisreleased.
LoggingstartswhentheuserpressestheMEMbuttonmomentarilyandendswhentheMEAUSURE
buttonisreleased.ThenumbershownontheLCDinthelowerrighthandcorner(data0–9)
indicatesthecurrentmemorylocation.Seeexampletime‐linediagrambelow.

1. PressandholdtheMEASUREbuttontobeginameasurementsessionasdescribedearlier.
2. WhileholdingdowntheMEASUREbutton,presstheMEMbuttonmomentarily.Thereading
onthedisplayatthetimeoftheMEMbuttonpress(initialreading)willbestoredinthe
currentreadingsetandtheMIN/MAX/AVGtrackingwillbegin.Notethereadingsetmemory
locationonthelowerrighthandcorneroftheLCD.
3. TheMIN/MAX/AVGreadingsarecalculatedoverthecourseofthemeasurementsession
(startingfromwhentheMEMbuttonispressedandendingwhentheMEASUREbuttonis
released).MIN/MAX/AVGreadingsarestoredinthesamereadingsetasthe‘initialreading’.
4. ReleasetheMEASUREbuttontoendthemeasurementsession.
5. Now,momentarypressesoftheMEMbuttonstepthroughtheinitialreading,MAX,MIN,
andAVGreadingsstoredinthecurrentmemorylocation.Notethatsubsequentpressesof
theMEMbuttonstepthroughtheremaining ninememorylocations;besuretonotethe
memorylocationnumberwhenreviewingdatatoavoidconfusion.
6. Whenrecallingdata,pressandholdtheMEMbuttontoquicklyjumpfromonereadingsetto
another.Thereadingsetnumber,onthelowerright,scrollswhiletheMEMbuttonisheld.
