CR1000 Manual - Campbell Scientific

Section 5. System Overview
CRBasic programming in the CR1000 facilitates creation of custom menus for the
external keyboard / display.
Figure Custom Menu Example (p. 70) shows windows from a simple custom menu
named DataView. DataView appears as the main menu on the keyboard display.
DataView has menu item Counter, and submenus PanelTemps, TCTemps and
System Menu. Counter allows selection of one of four values. Each submenu
displays two values from CR1000 memory. PanelTemps shows the CR1000
wiring-panel temperature at each scan, and the one-minute sample of panel
temperature. TCTemps displays two thermocouple temperatures., Custom
Keyboard and Display Menus (p. 508), and Keyboard Display (p. 70). The
CR1000KD can be mounted to a surface by way of the two #4-40 x .187 screw
holes at the back.

5.1.5 Power Requirements
Read More! See Power Sources (p. 82).
The CR1000 operates from a power supply with voltage ranging from 9.6 to 16
Vdc, and is internally protected against accidental polarity reversal. The CR1000
has modest-input power requirements. In low-power applications, it can operate
for several months on non-rechargeable batteries. Power systems for longer-term
remote applications typically consist of a charging source, a charge controller, and
a rechargeable battery. When ac line power is available, an ac/ac or ac/dc wall
adapter, a charge controller, and a rechargeable battery can be used to construct a
UPS (uninterruptible power supply). Contact a Campbell Scientific applications
engineer for assistance in acquiring the items necessary to construct a UPS.
Applications with higher current requirements, such as satellite or cellular phone
communications, should be evaluated by means of a power budget with a
knowledge of the factors required by a robust power system. Contact a Campbell
Scientific applications engineer if assistance is required in evaluating power
supply requirements.
