This menu screen selects the parameter trend to be displayed. Use the "↑"
and "↓" keys to select the parameter you want to display then press " ↵"
to view that trend screen. ESC will take you back to the main menu.
Consult the Menu Tree diagram, Figure 6-2, of this section to find the
menu/submenu location of individual screens.

6.4.12 View Numerical Data

There are four pages to the Numerical Data screen: One each for Flow,
Internal Temperature, External Temperature & Pressure, and Network &
MIO Status data. It is designed to be a place to simultaneously view all of
the parameters for a given type of measurement, i.e., flow, internal
temperature and so on. This is a good place to do a daily check of the
monitor since all values are updated concurrently. If readings are taken
from multiple screens, some differences in the readings may occur due to
updates occurring while you are switching screens.
The NETWORK & MIO STATUS screen contains the Multi I/O Status
word and several network event counters that keep a tally of the number of
times each of the eight possible network errors occurs. These are specific
errors defined by the network protocol. Each time one of the errors occurs
at the Enhanced Remote Display node, an error message is issued and the
network status log value for that error is incremented by one. These errors
do not necessarily require corrective action but happen due to network
contention issues that are a normal consequence of the network topology.
A full description of these errors is beyond the scope of this manual. If
necessary, please consult Teledyne Monitor Labs technical support for
more information.

6.4.13 View Status History

This Screen has up to twelve pages depending on the number of system
status changes that have taken place. It stores the previous 100 non-zero
status word changes. Consecutive, identical non-zero status words cause
only one entry. After one hundred entries the log is first in, first out. The
most recent entries are at the top of the list on page one. Each entry
consists of a code, the date, and time it occurred. Status words can be
decoded as per the STATUS CODE HELP screen.
