Computation
Averaging
(See section 8.1 for the procedure)
When the averaging function is used, the specified number (average count) of measured
values are averaged to derive the final displayed value. Therefore, the measured results
are more stable.
There are two averaging modes, block average and moving average.
Block average: The specified average count of measurements is carried out in a single
source measure cycle. The GS610 displays the result obtained by
summing the measured values and dividing the sum value by the
average count. Therefore, the measurement time takes average count
times as long.
Moving average: The GS610 measures once in a single source measure cycle. The
GS610 displays the result obtained by summing the average count of
measured values and dividing the sum value by the average count. If
the number of measurements does not reach the average count, the
average over the number of measurements is displayed.

The average count can be set in the range of 2 to 256.
When the averaging function is enabled, the average indicator on the left side of the
GS610 illuminates.
NULL Computation
(See section 8.2 for the procedure)
In NULL computation, a difference with respect to a given value can be displayed. The
NULL value is set to the measured value when the NULL computation is turned ON.
From that point, the GS610 displays the results obtained by subtracting the NULL value
from the measured values.
Displayed value = Measured value – NULL value
When the NULL computation is switched from OFF to ON, the measured value at that
point is automatically entered as the NULL value. However, this value can be changed
afterwards.
When the NULL computation is enabled, the NULL key illuminates.
Computation Using Equations
(See section 8.3 for the procedure)
Computation can be performed using equations provided in a text file. In computation
using equations, four arithmetic operations, trigonometric functions, and so forth can be
performed on variables such as source values and measured values as well as
constants.
For example, if an equation “m=I*V” is applied, the GS610 calculates and displays the
power.
The equation can be selected from the definition files in the MATH directory on the
internal GS610 ROM disk (see section 2.9, “USB Storage Function). For the definitions
files, you can use built-in computation files that are available when the GS610 is shipped
from the factory (or when the disk is formatted (see section 4.3, “USB Storage Function”)
and user-defined computation files that you create such as on a PC.
If the definition file contains an equation with variables A, B, and C, the values for A, B,
and C can be entered from the GS610 panel soft keys. Computation using equations
can be used not only to perform computation using measured values, but also to create
the next source value from the calculation.
