带有内置键盘和显示的研究级功率
Overview
CR850是一个较小的研究级数据记录仪，它在其集成软件包的一部分中包括板键盘显示。它旨在用于较小的配置，其中测量传感器较少。每个CR850都会从传感器读取输入，然后通过通信外围传输数据；大多数传感器和电信设备都是兼容的。可以将多个CR850配置为网络，也可以单独部署。这个坚固的数据记录器可以在苛刻的远程环境中提供独立的操作。

Detailed Description
The CR850 consists of measurement electronics encased in a plastic shell with an integrated wiring panel, 16- character keyboard, and display screen. The display can show 8 lines x 21 characters (64 x 128 pixels). Custom menus are supported allowing customers to set up choices within the data logger program that can be initiated by a simple “toggle” or “pick list”. Its keyboard and display screen is used to program the data logger, manually initiate data transfer, and display data.
The CR850 uses an external power supply. Low power consumption allows the it to operate for extended periods on a battery recharged with a solar panel—eliminating the need for AC power. The CR850 suspends execution when primary power drops below 9.6 V, reducing the possibility of inaccurate measurements.
The on-board operating system includes measurement, processing, and output instructions for programming the data logger. The 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.

Additional Compatibility Information
Sensors
With several channel types, the CR850 is compatible with nearly every available sensor, including thermocouples, SDI-12 sensors, and 4 to 20 mA sensors. A custom ASIC chip expands its pulse count, control port, and serial communications capabilities. The CR850's I/O ports can be paired as transmit and receive, allowing serial communications with serial sensors and devices.
测量和控制外围设备
CR850与我们的所有CDM兼容（需要SC-CPI），SDMS，多路复用器，振动线接口，终端输入模块和继电器。
Communications
The CR850 communicates with a PC via direct connect, NL201 Ethernet Interface, multidrop modems, short haul modems, phone modems (land line, digital cellular, and voice-synthesized), RF telemetry, and satellite transmitters (Argos and High Data Rate GOES).
可以在其板载键盘显示屏上查看数据，使用键盘，用户支持的iOS或Android设备（需要LoggerLink），CD295 Dataveiew II显示或用户提供的PDA（PCONNECT或PCONNECTCE软件））。
The SC115 is the only compatible external data storage device. The CR850 does not have a peripheral port and is therefore not compatible with the CFM100, NL115, or NL120.
Enclosures
The CR850 and its power supply can be housed in any of our standard enclosures.
Power
Any 12 Vdc source can power the CR850 datalogger. Power supplies commonly used with the CR850 are the BPALK, PS100, and PS200. The BPALK provides eight non-rechargeable D-cell alkaline batteries with a 7.5 A h rating at 20°C.
Both the PS100 and PS200 consist of a sealed rechargeable 7 A h battery and a charging regulator. Their battery should be connected to a charging source (either a wall charger or solar panel). These two power supplies differ in their charging regulator. The PS100 has a standard regulator and the PS200 has a micro-controller-based smart regulator. The PS200's regulator provides two-step constant voltage charging and temperature compensation that optimize battery charging and increases the battery’s life.
Also available are the BP12 and BP24 battery packs, which provide nominal ratings of 12 and 24 A h, respectively. These batteries should be connected to a regulated charging source (e.g., a CH100 or CH200 connected to a unregulated solar panel or wall charger).

CR800 OS v.32.05 (4.33 MB)01-06-2020
执行此下载将在计算机上安装CR800操作系统和编译器。它还更新了CRBASIC编辑器的CR800支持文件。
Note:This OS has crossed the 2 Meg CR800 size limit for remote download。必须通过与设备配置实用程序直接连接将操作系统下载到2兆CR800。所有操作系统下载方法均由4 MEG CR800支持。
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.
在所有在28之前从操作系统更新数据词架的情况下，建议使用DevConfig的备份实用程序，因为使用新的FAT32格式进行了格式化的CPU驱动器。

Yes.
-
Yes, using theDisplayMenu/EndMenu()andMenuIteminstructions.
-
No. The display has its own OS that is not programmable using CRBasic.
-
Baler2.2 was developed before the release of the CR800 and, therefore, does not work with it.The latest version ofBalerdoes work with the CR800 and can be found in the Downloads section ofthe Baler product page。
Note:作为新版本的Balerare released, upgrades to older versions may not work. The notes associated with the upgrade or patch indicate which previous version needs to be installed before installing the upgrade.

过载保护的上限是有限的evice on the wiring panel, which is a 1.5KE20CA. The key limit is for constant dc voltages; it starts to become leaky as the voltage increases and reaches the range of its nominal surge clamp voltage of 20 V. It is possible to damage that component if the voltage is continuously held near its clamp voltage, causing it to dissipate a lot of power.
There are also other issues of internal heat generation, which could increase measurement errors at high temperatures—especially if powering sensors or peripherals from the data logger.
这就是为什么引用16 V的限制的原因，该限在铅酸电池的正常运行电压范围内。如果电压略高于此，尤其是在冷时，则不会引起问题。

Use the CRBasic Editor inLoggerNetorPC400。
-
Yes. Many customers use the Iridium satellite transceiver.
-
LoggerNet在Linux版本中可用（lnlinux).
-
Yes. The CR800 and CR850 are compatible with exactly the same options as the CR1000 but with a lower channel count.
-
No, unless the internal lithium battery is below 2.7 Vdc. The lithium battery helps preserve the data, program, and clock setting when the 12 Vdc battery is removed.
