ol Starting and stopping a series of measurements
 Select the first soft-key page of the standard screen.
 Press the START MEAS. SERIES soft key to start a series of
measurements. If the START SPC soft key is displayed on the
screen, press the SPC [MEAS. SERIES] soft key to open the SPC
menu, and then press the SPC [MEAS. SERIES] soft key to switch
to the SERIES OF MEASUREMENTS mode (see "Switching
between series of measurements and SPC mode" on page 42). If
the ND 287 is configured for two axes and the display mode X1:X2
is not active, then the ND records the values for both axes
simultaneously after the series of measurements has been started.
The ND can store up to 10000 values per axis. The measured-value
counter is shown on the left side of the message line. It shows the
number of the current value being measured and the total number
of values to be measured, e.g. 0/50.
 If required, you can switch the display mode during the series of
measurements by pressing the SELECT DISPLAY soft key (see
"Defining the display for a series of measurements" on page 46). The
currently active display mode is highlighted in the status display:
MIN, ACTL, MAX or DIFF.
 You can stop the current series of measurements at any time by
pressing the STOP MEAS. SERIES soft key. When the defined
number of measured values has been reached, the ND stops the
series of measurements automatically.
 The DYNAMIC RESET soft key appears only if you use the ENTER
key or an external signal for saving and if you have selected the MIN,
MAX or DIFF recording mode. If you press this soft key, the MIN,
MAX and DIFF values are reset to zero.
All parameters required for a series of measurements and the
possibility of analyzing a previously recorded series of measurements
are provided by the SERIES OF MEASUREMENTS menu.
