Scaling Configuration
The second step of the channel configuration guide: configure the scaling
parameters.
Figure 2-5 Scaling Configuration
Note: for multiplexer channels that are using the “SENSOR” function and the DIO
and TOT channels of the multifunction module, the configuration guide does not
contain scaling configuration. Also note that the multiplexer channels that are not
using the DMM module, the configuration guide also does not contain “Scaling
Configuration”.
The M300 provides a scaling function. This function has three scaling coefficients (A,
B and C) for all the readings of the channel selected. The formula for the scaling
function is as follows.
Scaling Reading = A×(x-x1)
2
+B×(x-x1)+C
Wherein, x is the reading measured. x1 is the correction value (can be a reading
measured at certain time or a value defined by user). Substracting x1 from all
readings can correct the zero point of the fitting curve.
You can configure the scaling function for all the multiplexer channels (except
channels using the “SENSOR” function or when external DMM is connected). Before
applying the scaling function, you must configure the measurement parameters of
the channel. After applying the scaling function, if the measurement function is
modified, the scaling function will be disabled and the scaling coefficients will be
reset.
