Function:Track–Definesthecurrentfunction.Inthiscase,theTrackfunction.
Z‐Rel–DefinestheZeromode.SensorZerocanbe referencetoanabsolutezeroorarelative
zero,indicatedrespectivelybyZ‐AbsandZ‐Rel.
Nov11,2013&4:11:34PM‐Thesevaluesrepresentthe
currentdateandtime.Theyareupdated
inrealtime.
BatteryIndicator–Avisualindicationofhowmuchchargeremainsinthebattery.
0.0000–Representsthecurrentliveloadonthesensor.Thisvalueisupdatedinrealtime.
lb–Representstheselectedengineeringunitsforthe
sensor.
High,PassandLow–Limitindicators,showinginrealtime,thestatusoftheloadonthesensor.
Menu–ClickingMenuentersthePMAC3000Menu.SeetheMenusection.
+Peak–Representstheother5functions.ClickingthisbuttonwillchangetheFunctionmodeto
whichever function is displayed in the button.The function displayed in the button, and
thereforeactivatedbythebutton,isselectedinthePMAC3000Menu.SeetheMenusection.
Tare–ClickingTarewillzerothesensor.InZ‐Absmode,thezerowillbetakenfromtheabsolute

+Peak,‐Peak&+/‐Peak
ThePeakfunctionssamplethesensoratarateof10,000readings/second.InallPeakfunctions,
theprocessstartswhenareadingisgreaterthanorequaltotheuserdefinedsensorThreshold
valueandendswhenthereadingstaysbelow80%oftheuserdefinedsensorThresholdvalue for
morethan100milliseconds.SeeFigures6&7.Upontheexpirationofthe100millisecondtimer,
theprocessisconsideredcomplete andthe peakvaluewillbedisplayed.Also,atthistime,the
limitswillbeevaluatedanddisplayed.Ifthereadingrisesabove80%oftheuserdefinedsensor
Threshold value before the 100 millisecond timer has expired, the process is not considered
completeandwillcontinue.
