DataView II (CD295) Dual Line Display
Temperature
1.234 deg C
Description
Value Units
The top line contains a string referred to as the ‘Description’, and the second
line contains both the value retrieved from a Public Variable in the datalogger
and a string referred to as ‘Units’. The value displayed on the second line can
be displayed with a user-selectable number of decimal places.
Together, the combination of ‘Description’, Public Variable, ‘Units’ and
number of decimal places, is referred to as a ‘screen’. The CD295 is capable of
holding and displaying up to 30 ‘screens’. There are no limitations on the order
of screens, or which Public Variables are displayed. Pressing the buttons on the
front panel of the DataView II will cause the next (or previous) screen to be
displayed.
The CD295 will attempt to collect a new value from the datalogger under the
following conditions:
• The user has changed ‘screen’
• The scan interval of the datalogger has expired
After some time (default 10 secs), the backlight will turn off, however the text
will remain visible until the unit enters sleep mode (default 120 secs).
Whenever one of the buttons on the front panel is pressed, these two timers
(Backlight timer and Power Down timer) are both reset. As a result, the
DataView II can be woken from sleep mode by pressing either of the buttons.
While in sleep mode the DataView II will continue to respond to PakBus
communications, however the LCD is turned off and no requests are sent to the
datalogger.
