技术说明
紧凑型的集成套CR3000，含有测量控制电子单元、通讯端口、16-键键盘、LCD显示器、供电电源以及手提把手，非常便携。一体式LCD显示器128x64像素绘图式或8行字符数值显示的功能。
CR3000有3种底座选项：碱性电池底座、可充电电池底座、无电池底座。CR3000的功耗非常低，配一块太阳能板给它的电池充电，就可以让CR3000一直工作，从而不需要交流电源。为了减小非精确测量的可能性，当主电源低于 9.6 V时，CR3000会暂停工作。
内部的操作系统包括数据采集器编程所需的测量、处理、输出指令。编程语言为CRBasic，使用类BASIC语法。测量指令包括：电桥设置、电压输出、热电偶、脉冲/频率信号。处理指令包括：代数运算、统计及用于现场处理的超越函数。输出指令按时间段处理数据，或控制外部设备。

Additional Compatibility Information
传感器
CR3000 包含数种类型的通道，可支持几乎每种可用的传感器，包括：热电偶、SDI-12 传感器、和 4 到 20 mA 传感器等。定制的ASIC (特定应用相关的集成电路) 芯片扩展了CR3000的脉冲计数、控制口和串行通讯的功能。CR3000的 I/O 端口 (控制口) 可以成对分别作为接收和发送使用，允许与串口传感器和设备进行通讯。
测量和控制外设
CR3000 可兼容我们所有当前的 CDMs (需要一个 SC-CPI接口模块)，SDMs，扩展板，振弦接口模块，端子输入模块和继电器等。
通讯
CR3000 与 PC 之间的通讯可以通过多种方式进行，包括：直接通讯，以太网接口 (NL100, NL115, NL120)，多子站总线 modem，直拽 modem，电话 modem (固话、数字手机网络和语音合成电话)，射频电台通讯，和卫星发射器 (Argos、高数据速率的 GOES 以及 Meteosat)。
查看数据可通过集成的键盘显示器，iOS 或 Android 设备 (需要 LoggerLink软件)，CD295 DataView II 显示器，Archer-PCon 现场 PC，或用户提供的 PDA (需要 PConnect 或 PConnectCE 软件) 进行。
兼容的外部数据存储设备包括 CFM100，NL115 和 SC115。
机箱
CR3000 能够被安放在 ENC12/14、ENC14/16、ENC16/18、ENC24/30 或 ENC24/30S 防护机箱内。
供电
CR3000 一般由自身的碱性电池或可充电电池供电电源 (见 订购栏)。当使用可充电电池时，它内部的 7 A h 密封可充电电池需要通过汽车电瓶 (需要 DCDC18R)、太阳能板或交流充电源来充电。
CR3000 还可以搭配不带电池的底座，这时需要用户提供直流电源。当系统的功耗要求较大容量的电池时，或当要求数据采集器的所占空间更小重量更轻的优点时，优先使用不带电池的底座。
软件
CRBasic 是用于 CR3000的全套编程语言，可支持简单或复杂的编程指令，以及多种内置的数据删减处理方法。CR3000所兼容的软件包括：
- Short Cut 快捷软件
- PC200W
- PC400 (1.3 或更高版本)
- LoggerNet (3.2 或更高版本)
- RTDAQ (1.0 或更高版本)

下载
CR3000 OS v.32.07 (4.39 MB) 15-05-2024
Execution of this download installs the CR3000 Operating System and Compiler on your computer. It also updates the CR3000 support files for the CRBasic Editor.
Note: The Device Configuration Utility is used to upload the included operating system to the datalogger.
Upgrading from versions prior to version 28 of the Operating System will reset the datalogger’s CPU drive. This is due to a change in the format of the file system from FAT16 to FAT32. In order for the datalogger to operate correctly, as part of the upgrade, the CPU drive is formatted to FAT32. Any programs stored and running from the CPU drive will be lost. It is not recommended to update the datalogger’s Operating System over a remote connection where program control regulates the communication equipment (turning it on or off, etc.). In these cases, an on-site visit and a backup using DevConfig’s backup utility is necessary to update the datalogger’s Operating System.
Watch the Video Tutorial: Sending an OS to a Local Datalogger.
In all cases where the datalogger is being updated from an Operating System prior to 28, the use of DevConfig’s backup utility is recommended due to the CPU drive being formatted using the new FAT32 format.
Device Configuration Utility v.2.30 (46.9 MB) 02-10-2024
A software utility used to download operating systems and set up Campbell Scientific hardware. Also will update PakBus Graph and the Network Planner if they have been installed previously by another Campbell Scientific software package.
Supported Operating Systems:
Windows 11 or 10 (Both 32 and 64 bit)

Look for a stamp on top of the battery. The stamp may be in a date format of YYMMDDXX where:
- YY is the year.
- MM is the month.
- DD is the day.
- XX is the manufacturing plant.
This indicates the age of the battery.

是，使用下面的步骤：
- 使用键盘，按下面菜单操作：Configure, Settings (配置，参数) | Display (显示) | Timeout (min) (超时，分钟):.
- 选择 Enter (回车键)。
- 键入想设置的超时分钟数值。
- 再次选择 Enter (回车键)。
-
Yes, but only if all the other data loggers are PakBus devices, such as the CR800, CR850, and CR1000.
-
No. The CR23X program must be translated into CRBasic using the Translator software or by hand.
-
Yes. Contact Campbell Scientific for replacement pricing and availability.
-
The RS-232 port is used for communication with computers, modems, and radios. It is also used for communicating with, and retrieving data from, serial sensors.
- The RS-232 port on CR3000 and CR5000 dataloggers is electrically isolated.
- The RS-232 port on the CR800, CR850, and CR1000 is not isolated. For these data loggers, it may be preferable to connect ac-powered PCs to the CS I/O port instead of the RS-232 port to avoid ground loops on some measurements.
-
Use the PreserveVariables() instruction to ensure that all variables reflect the last known value if the data logger experiences power loss.
-
With the CR1000, CR800, CR850, and CR3000, connection between RS-232 ports is possible. The connection requires a null modem serial cable to cross the transmit and receive lines.
-
No. The NL120 is used for one device only.
-
Yes. The simplest method is to use conditional program statements that execute most of the code based on time. For example, the data could be scheduled to log at 6 a.m. and finish at 8 p.m. using CRBasic instructions such as TimeIntoInterval(). Another option is to use an IfThen/EndIf construction that does a logical test of light-level measurements based on a light sensor. An additional option is to use calculated sunrise and sunset times along with a combination of RealTime() and Case instructions.
