603 calculates energyon thebasis of theformulastated inEN1434‐1, whichusesthe international
temperaturescaleissuedin1990(ITS‐90)andthepressuredefinitionof16bar.
Inasimplifiedformtheenergycalculationcanbeexpressedas:Energy=Vxxk.
Thecalculatoralwayscalculates
energyinWh,andthenconvertsthevaluetotheselectedmeasuringunit.
EWh=
Vx
 xkx1000
EkWh= EWh/1,000
EMWh= EWh/1,000,000
EGJ= EWh/277,800

Bothinthedisplayandduringdatareadingeachenergytypeisuniquelydefined,e.g.

Heatenergy:E1=V1(t1‐t2)k

Coolingenergy:E3=V1(t2‐t1)k


 k istheheatcoefficientofwater,calculatedaccordingtotheformulaofEN1434andOIMLR75‐1:2002.
