4.4
Calculation function
Please refer to various operations of the following Sections 4.4.1 to 4.4.6. Simultaneous setting is
possible.
However combination of scaling calculation and decibel calculation cannot operate and set
simultaneously.
4.4.1
SMOOTHING (Moving average) calculation
Average count
Is selectable in range of 2 to 100 (positive integer).
*In case trigger is SINGLE, after it reaches the set average count,
required trigger sample quantity is obtained.
4.4.2
NULL (Difference) calculation
Calculation
Calculation result =RAW value-NULL value
RAW value
Measured value of function at that time
NULL value
Value set by following "NULL value setting".
Setting
Calculation ON/OFF
On/Off are set by [ NULL ] key or NULL menu of each function.
*When turning on with the NULL key, the measured value at that time
is set to NULL value of each function.
NULL value setting
It is possible to set it by three kinds (DEFAULT value, measurements,
and a numeric input) when setting according to the NULL menu of each
function.
Numerical setting by NULLVAL menu of each function manually.
With multiplier (p, n, μ, m, k, M, G, T), effective figures 7 digits
4.4.3
Scaling calculation
*This cannot be set with section 4.4.4 decibel calculation (dB calculation) simultaneously.
Calculation formula
Two kinds of the following can be selected.
• Display value = (Measured value -A) *B/C
• Display value = D/Measured value
Constant
The 4 constants of A, B, C, D are set.
Valid digit
7
Multiplier
8 types of p, n, μ, m, k, M, G, T
