Performing Statistical Computation with
the Measurement Value

Statistical computation with the measurement value can be performed. The data to be used for
the statistical computation is the one held in each measurement mode. OUT1 and OUT2 can
perform statistical computation independently.

Up to 90000 statistical data can be acquired. If the number exceeds 90000, the statistical
computation stops.

The statistical computation is performed and the statistical data is updated continuously.

The statistical data is cleared under the following six conditions:

• When the

key is pressed for three seconds

• When moving to the Measurement mode from the Setting mode, Tolerance Settings

mode, Program Change mode, or Communication mode

• When the statistics clearing command is received via the RS-232C interface
• When the clearing operation is performed on "LK-Navigator" software
• When a program No. is switched
• When the power is turned off

The upper OUT1 display shows the name of the statistical data, and the lower OUT2 display
shows the statistical data.

The statistical data consists of the following 11 items.

* M is displayed as "

1

" at OUT1, and as "

2

" at OUT2.

Refer to "Using the Hold Function (Measurement Mode)" (page 3-25).
