Operating System/Logic Control
e on-board operating system includes measurement,
processing, and output instructions for programming
the datalogger. e programming language, CRBasic,
uses a BASIC-like syntax. Measurement instructions
specific to bridge configurations, voltage outputs,
thermocouples, and pulse/frequency signals are
included. Processing instructions support algebraic,
statistical, and transcendental functions for on-site
processing. Output instructions process data over
time and control external devices. ese instructions
include averages, maximums, minimums, standard
deviations, histograms, rain ow histograms, level
crossings, and Fast Fourier Transfers (FFTs).
Data Storage Capacity
Data and multiple programs are stored on-board in
battery-backed SRAM. Data is stored in a table for-
mat. Up to 900,000 low-resolution data points can
be stored in its CPU memory. Storage capacity can
be increased by using a PC or CompactFlash card.
CR5000
Measurement and Control System
The CR5000 Measurement and Control System is a self-contained, low power, rugged datalogger that is capable of a maximum
throughput of 5 kHz. Standard operating range is -25° to +50°C; an optional extended range of -40° to +85°C is available.
Keyboard—allows on-site program
editing and command entries.
128 x 64 Backlit LCD—
provides a graphical or 8-line
numeric data display.
Computer RS-232
provides a
ted DCE port
-pin electrically isola
CS I/O Port—connects data
transfer peripherals.
PCMCIA Card Slot—accepts
a single Type I, Type II, or
Type III card or the CFI adapter
and a CompactFlash card.
Removable Input/
Output Connections—
Individually con gured
for ratiometric resistive
bridge, thermocouple,
switch closure, high
frequency pulse, low-
level ac, serial sensors,
and more.
