DISPLAY MODE SELECTION
Use the up/down arrow buttons to highlight the required display
mode. Once the required display mode is highlighted, operation of
the scroll button causes the recorder to leave the ‘Go to View’ menu
and to display channel values in the selected mode. See Section 4.4
for a description of the various display modes.
Alternatively the up and down arrow buttons can be used from any of
the display modes to cycle through the available modes in the order
listed in the figure.
Notes:
1. If an option (e.g. ‘Steriliser’) is not fitted, its display mode
is not available for selection.
2. Some display modes must be enabled in Instrument.
Display configuration before they become available.
4.3.4 History
This top level menu item allows the user to switch from real-time
trending to review mode, where channel values, messages, alarm
triggers etc. can be viewed back as far as the last significant
con.figuration change. History mode is discussed in Section 4.5
4.3.5 Faceplate Cycling on/off
For the purposes of this document the channel whose faceplate is currently displayed and whose ‘pen’
symbol is visible is called the ‘Active’ channel.
By default, the recorder scrolls through all the channels in the display group, with each channel becoming
the active channel in turn. This top level menu ‘Faceplate Cycling’ item allows the user to inhibit this
scrolling action such that the currently active channel remains active permanently, or until a manual scroll
is performed using the scroll button (or until Faceplate Cycling is re-enabled).
‘Faceplate Cycling’ is highlighted by using the up/down arrow buttons. Once highlighted, the status can
be changed from ‘On’ to ‘Off’ or vice-versa using the scroll button. Operation of the ‘Page’ button returns
the user to the trend display.
4.3.6 Operator Notes
This area allows up to 10 notes to be created when logged in as Engineer, using either the text entry
techniques described in Section 4.6, or ‘iTools’ described in Section 6. Once logged out, operating the
scroll button whilst a note is highlighted calls a selection box allowing the user either to send that note to
the chart, or to write a Custom Note.
CUSTOM NOTE
The Custom Note is written using the text entry techniques described in Section 4.6. Once the note is
complete, operation of the page button calls a confirmation display. The down arrow is used to highlight
‘Yes’, and when the scroll key is then operated, the message is sent to the chart. This custom message is
not retained for further use, so if it is required on a regular basis, it is suggested that one of the Operator
Notes 1 to 10 be configured (Engineer access level required) so that it may be used instead.
Note: Each note can contain up to 100 characters.
4.3.7 Demand Archiving
This allows a user, with a high enough access level, to archive a selected portion of the recorder history,
either to a ‘memory stick’ plugged into the USB port at the rear of the recorder (Local Archiving), or to a
pc, by means of the FTP protocol (Remote Archiving). The archived data remains in the flash memory of
the instrument. When the flash memory is full, new data causes the oldest file(s) to be discarded.
The up and down arrow keys are used to navigate to the required field.
