Calculation Functions
•
NULL calculation
Display value (NULL) = Measured value - NULL constant
•
Smoothing calculation
Display value (SM) = Moving average over a specified number of measurements
•
Comparator calculation
Display (HIGH)
HIGH setting value < Measured value
Display (LOW)
Measurement value < LOW setting value
Display (GO)
LOW setting value
Measured 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 measured value after the calculation starts
Display value (MIN) = Minimum measured value after the calculation starts
Display value (AVE) = Averaged value after the calculation starts (Remote output only)
•
dB and dBm calculation
dB display = 20 log (Measured value/D)
dBm display value = 10 log ((Measured value)
2
/D)/10
-3
D is a constant. (Set by the user)
•
Statistical calculation
Number of samples
Display value (SAMPLE) = Number of measured values in the specified range
of the measurement memory
Maximum value
Display value (MAX) = Maximum measured value in the specified range of
the measurement memory
Minimum value
Display value (MIN) = Minimum measured value in the specified range of the
measurement memory
Average value
Display value (AVE) = Averaged 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 measured value) - (Minimum measured
value)) in the specified range of the measurement memory
•
Calculation between 2 measurements
Display value (M1+M2) = Left side display: M1 + Right side display: M2
Display value (M1-M2) = Left side display: M1 - Right side display: M2
Display value (M1*M2) = Left side display: M1 * Right side display: M2
Display value (M1/M2) = Left side display: M1 / Right side display: M2
