RATIO functions
The Model 6482 has built-in RATIO functions to calculate the following:
•MSR1/MSR2
•MSR2/MSR1
MSR1/MSR2
This function computes the ratio between the channel 1 measurement function (MSR1) and the
channel 2 measurement function (MSR2):
RATIO = MSR1/MSR2
Where: MSR1 = Channel 1 measurement function
MSR2 = Channel 2 measurement function
MSR2/MSR1
This function computes the ratio between the channel 2 measurement function and the channel 1
measurement function:
RATIO = MSR2/MSR1
where: MSR1 = Channel 1 measurement function
MSR2 = Channel 2 measurement function
DELTA functions
The Model 6482 has built-in DELTA functions to calculate the following:
•MSR1-MSR2
•MSR2-MSR1
MSR1-MSR2
This function computes the difference between the channel 1 measurement function and the
channel 2 measurement function:
DELTA = MSR1-MSR2
Where: MSR1 = Channel 1 measurement function
MSR2 = Channel 2 measurement function
MSR2-MSR1
This function computes the difference between the channel 2 measurement function and the
channel 1 measurement function:
DELTA = MSR2-MSR1
Where: MSR1 = Channel 1 measurement function
MSR2 = Channel 2 measurement function
