4. Select the Accept Input softkey or touch the screen anywhere inside the
directory window other than the selected parameter box to return the control
knob to its scrolling function.
Note that setting a pair of limits backward (setting an upper limit lower than its
lower limit) will always display an error flag on the Auto mode display. Alarm
Limits may be set inside Caution Limits, but then only Alarm Limit violations
will be flagged.
The limit file used by Auto mode is designated in the configuration file
(Channel_A/B/C Configuration) for each channel. A file from the Selected
Measurements directory is used in conjunction with a file from the Auto_Limit
Files directory to provide Auto mode with a list of desired measurements and
limits for those measurements.
You can specify the zero carrier pulse location and/or whether or not you wish to
use it as a reference and define the locations of test signals on VITS lines (or in a
full field signal) within a file in the Measurement Locations directory. The files
found in this directory contain information used by both Auto and Measure
modes. The measurement locations file used by Auto and Measure modes is
designated in the configuration file (Channel_A/B/C Configuration) for each
channel. The System Default file is the only file available for selection when the
instrument is shipped. Any additional files you create to customize your
applications will be available for selection.
The files used to designate which subset of measurements you wish Auto mode
to perform are found in the Selected Measurements directory.
The files found in this directory contain a list of all the measurements Auto
mode can perform. The purpose of the files is to allow you to select a subset of
measurements you wish to perform from the entire list of measurements
available. A selected measurements file is used in conjunction with an auto limit
file to provide Auto mode with a list of desired measurements and the limits at
which those measurements generate caution and alarm messages.
Note that the mnemonic of each measurement name used in remote operation is
listed to the left of the measurement name.
The Selected Measurements system default file is the only file available for
selection when the instrument is shipped. Use the Create File softkey to create a
new file you can customize.
Selecting or deselecting a particular measurement is simple. After opening the
desired file, use the control knob to scroll the file so the desired measurement is
highlighted. Note that the labels Selected and Not Selected are printed below the
directory window. Touch the highlighted line on the Selected side of the screen
