Calculation Functions
•
NULL calculation
Display value (NULL) = Measurement value - NULL constant
•
Smoothing calculation
Display value (SM) = Moving average over a specified number of measurements
•
Comparator calculation
Display (HIGH)
HIGH setting value < Measurement value
Display (LOW)
Measurement value < LOW setting value
Display (GO)
LOW setting value
Measurement value
HIGH setting value
•
Scaling calculation
Display (SCL) = (Measurement value - B)/A
C
A, B, and C are constants. (Setting values)
•
MAX and MIN calculation
Display value (MAX) = Maximum measurement value after the calculation starts
Display value (MIN) = Minimum measurement value after the calculation starts
Display value (AVE) = Arithmetic mean after the calculation starts (Remote output only)
•
dB and dBm calculation
dB display = 20 log (Measurement value/D)
dBm display value = 10 log ((Measurement value)
2
/D)/10
-3
D is a constant. (Set by the user)
•
Statistical calculation
Number of samples
Display value (SAMPLE) = Number of measurement values in the specified
range of the measurement memory
Maximum value
Display value (MAX) = Maximum measurement value in the specified range
of the measurement memory
Minimum valu
Display value (MIN) = Minimum measurement value in the specified range
of the measurement memory
Average value
Display value (AVE) = Average value in the specified range of the measure-
ment memory
Standard deviation
Display value (SIGMA) = Standard deviation in the specified range of the
measurement memory
Dispersion
Display value (P-P) = ((Maximum measurement value) - (Minimum measure-
ment value)) in the specified range of the measurement memory
