Overview

The CR23X-4M could store over 2,000,000 data points.

The CR23X-4M Micrologger® was a portable, self-contained package. It consisted of measurement and control electronics, communication ports, keyboard, 2-line alphanumeric display, power supply, and a battery-backed clock. The CR23X-4M measured most sensor types directly, communicated via modems, reduced data, controlled external devices, and stored both data and programs in either non-volatile Flash memory or battery-backed SRAM.

Detailed Description

The CR23X-4M is a self-contained, rugged data logger that can measure most sensor types directly, communicate via modems, reduce data, control external devices, and store both data and programs in either non-volatile Flash memory or battery-backed SRAM.

The CR23X-4M has an integral, 2-line, alphanumeric display and power supply. A battery-backed, real-time clock and 4M of nonvolatile data storage is included. The CR23X-4M Microloggers are available with a sealed rechargeable battery base, an alkaline base, or in a low-profile version without batteries.

Frequently Asked Questions

Number of FAQs related to CR23X-4M: 2

  1. A practical maximum is to connect one multiplexer per every two control terminals on the data logger. Control terminals can be shared between multiplexers to increase the number of connected multiplexers. Sharing terminals, however, requires more complex wiring and programming. Users who would like to connect more than one multiplexer per every two control terminals are advised to contact a sales or support engineer at Campbell Scientific for assistance.

  2. E08 errors are occasionally created by voltage surges or transient voltages. Section 3.9 of the CR23X manual explains in greater detail what a watchdog is and possible causes.  If these are happening frequently, it is likely an issue with the system  that needs to be resolved. The first step in this resolution process would be to check the system power (inputs and outputs) and verify it is within the expected tolerances as outlined in the Specifications page (OV-23) of the CR23X Micrologger Operator's Manual
