f ) OLED Screensaver (SS) Time Out Feature (Numerical entry)
This menu selection defi nes a time interval in seconds from the moment the local Esc
button or joystick interface was last used (or, if neither was used, from the power up
event) to the moment the Screensaver is activated. Each time the user activates the
local Esc button or the joystick interface, the OLED brightness reverts to normal
“Operational Brightness Level” and the internal timer resets to zero, starting a new
delay cycle. The default setting is 900 seconds (15 minutes).
g) OLED Screen Saver Brightness (Numerical entry)
Using OLED Screen Saver Brightness settings, the user can adjust the desired level of
the OLED brightness during "Low Brightness" screensaver mode (when the screen
saver is active). The brightness has 127 different levels.
NOTE: If Screensaver mode is active and has been changed, new settings will
be activated in the next Screensaver cycle (after the Esc button or joystick
interface was activated to disable the currently active screensaver). The OLED
“Screensaver Brightness Level” parameter is only applicable for “Low
Brightness” Screensaver mode. In “Vertical Scrolling” mode, the normal
operational brightness level will be activated. If OLED display is not used in the
user application (e.g., the instrument is installed in a remote enclosure), we
recommend setting the Screensaver mode to "OLED Off".
h) Flow Rate Precision (Tabular entry)
The DPC Flow Controller calculates Flow Rate Precision automatically, based on
selected units of measure and current gas full scale fl ow rate to keep best reading
precision. By default, the Flow Rate Precision is set to “Normal”. In cases where more
digits after the decimal point are required, the user can change decimal point precision
to the “Elevated” level (one more digit after the decimal point).
NOTE: In some cases, selecting “Elevated” precision may result in unstable
readings (the last digit constantly changes). In such cases, we recommend
switching the decimal point precision to the “Normal” level.
6.4.15.4 Submenu “Communication Port Settings”
This menu selection allows the conifi guration of a main digital communication interface
type (RS-232 or RS-485), speed (Baud rate) and device RS-485 bus address and termination
mode (only applicable for RS-485 interface).
The following settings are available for “Communication Settings” (see Figure 19):
