Computation (Uniquely for DA100 with /M1 option)
The DA100 can execute computations with the measured data of each input channel
taken as a variable. The results can be displayed or saved. The following operators can
be used for computation.
Basic operators
Type Operator Example Description
Addition + 001+002 To obtain the sum of the measured data of channel 001
and channel 002.
Subtraction - 002-001 To obtain the difference of the measured data of
channel 002 and channel 001.
Multiplication * 003*K1 To multiply constant K1 to the measured data of channel
003.
Division
/ 004/K2
To divide the measured data of channel 004 by constant
K2.
Power ** 005**006 To take the power of measured data of channel 005 with
the measured data of channel 006.
Absolute
value ABS() ABS(001) To obtain the absolute value of the measured data of
channel 001.
Square root SQR() SQR(002) To obtain the square root of the measured data of
channel 002.
Common
logarithm LOG() LOG(003) To obtain the common logarithm of the measured data
of channel 003.
Natural
Logarithm LN() LN(004) To obtain the natural logarithm of the measured data of
channel 004.
Exponent EXP() EXP(005) To make the measured data of channel 005 to be x and
obtain e
x .
* +/- can be used as signs as in -(001).
