Function Details
Math Expression
•
Voltage Coefficient (VOLTCOEF)
•
Varistor Alpha (VARALPHA)
In the following formula, [
c
] specifies the channel used for the measurement.
However B2980 supports 1 only at this time. For example, the current
measurement scalar data is given by CURR1 or CURR.
For the predefined math variables used in the following formula, see
Used in the Expressions” on page 226
MXPLUSB
Adjust scale and offset for the current measurement data using the following
formula.
MXPLUSB = M * CURR[
c
]
B
where, M and B are the predefined math variables.
MRECPXPLUSB
Adjust reciprocal scale and offset for the current measurement data using the
following formula.
MRECPXPLUSB = M / CURR[
c
]
B
where, M and B are the predefined math variables.
RATIO
Calculates ratio between the current measurement data and predefined math
variable data TARGET using the following formula.
RATIO = CURR[
c
] / TARGET
PERCENT
Calculates the percentage of the current measurement data for the predefined
math variable data TARGET using the following formula.
PERCENT = CURR[
c
] / TARGET * 100
DEVIATION
Calculates deviation of the current measurement data from the predefined math
variable data TARGET using the following formula.
DEVIATION = (CURR[
c
]
TARGET) / TARGET
PERDIV
Calculates percent deviation of the current measurement data from the predefined
math variable data TARGET using the following formula.
PERDIV = (CURR[
c
]
TARGET) / TARGET * 100
LOG10
Calculates base 10 logarithm of the current measurement data using the following
formula.
