Adding a new measuring point that is not using the RMS base units.

[James]

When adding a measuring point to RMS, the system considers the basic units to be the following:

a.Temperature: °C.
b.Pressure: hPa.
c.Differential pressure: Pa.
d.Flow velocity: m/s.
e.Particle: Particle count/m3.
f.Airflow: m3/h.
g.CO2: PMM

Should a measuring point be added, that does not correspond to the basic unit, then it must be added as an analog measuring point. The measurement point's value will automatically be calculated when selecting a unit under local settings.

In order to make this easier to understand, please see the table below, created using the example of a device delivering a value in °F that is not an RMS base unit, then a device that is delivering a value in °C, that is an RMS base unit.

Device value	Add MPT as	RMS (system settings)	Value shown in RMS
°F	Temperature	°C	°C
73,4		73,4	73,4
Device value	Add MPT as	RMS (system settings)	Value shown in RMS
°F	Temperature	°F	°F
		73,4*9/5+32
73,4		164,12	164,12
Device value	Add MPT as	RMS (system settings)	Value shown in RMS
°F	Analog		°F (input manually)
73,4		73,4	73,4
Device value	Add MPT as	RMS (system settings)	Value shown in RMS
°C	Temperature	°C	°C
23		23	23
Device value	Add MPT as	RMS (system settings)	Value shown in RMS
°C	Temperature	°F	°F
23		73,4	73,4
°C	°F
1	33,8
23	73,4

Hello,

When adding a new measuring point that doesn’t use the RMS (Root Mean Square) base units, it’s important to consider the type of measurement you’re dealing with and the context in which it will be used. RMS is a statistical measure used to calculate the effective value of an alternating current (AC) waveform, typically expressed in meters per second squared (m/s²) for acceleration.

If you’re working with a different type of measurement or a non-sinusoidal waveform, you might need to use a different method to represent the effective value accurately. For instance, if you’re measuring direct current (DC) or if the waveform is distorted with harmonics, you might need to use the True RMS value, which provides an accurate measurement of the actual effective value of any AC waveform, regardless of its shape.
