The Simple Logger II Model L404 is a four-channel event data logger. It is a cost-effective, advanced design data logger incorporating features and functions not found in data loggers costing 2 to 3 times its price. Event data is stored only as the event occurs. It works with dry contact closure or 0-3 and 0-5VDC logic levels.
Internal memory allows storing over 50,000 events; more than enough for most data collection needs. Event measurement scaling is user-programmable. Battery operation and compact size allow for installation in tight locations without the need for external power. A series of front panel LEDs provide a quick status of the logger’s state and memory usage.
DataView application software is included, providing real-time viewing of measurement data, even while recording. Instrument configuration, data storage, and report generation from a pre-defined template or operator custom-designed templates are also standard features.
DataView Graphing & Analysis Software
The DataView software provides a convenient way to configure and control logging from your computer. Through the use of clear and easy-to-use tabbed dialog boxes, all Simple Logger II functions can be configured and tests can be initiated. Results can be displayed in real-time and stored in your PC or the logger. Standard or custom reports may be printed along with the operator’s comments and analysis.

3 Recording Modes
Start/Stop Mode
In this mode, the operator selects a storage rate from predefined values from 8 per second to 1 every day, then selects a start and stop time. Data is recorded at this rate until the memory is filled or the end recording time and date is reached. The logger then stops recording and goes into standby mode retaining the recorded date.
First In First Out Mode (FIFO)
The operator makes the data storage and recording length selections as described above. If the memory fills before the end date and time occurs, the logger will discard the oldest stored data point and add a new one. This process will continue until the end recording date and time is reached.
Extended Time Recording Mode (XRM)
This unique recording mechanism provides for continuous recording over a longer period of time without the need for the operator's selection of adjustments. The operator selects a starting storage range from predefined values from 8 per second to 1 every day and a recording length. The logger will store data at the rate selected until the memory is filled. The logger will then discard every other stored sample beyond the first one, freeing up half the memory for continuous recording. New samples will be stored at half the previous storage rate, matching the interval with the remaining stored data. This process will repeat each time the memory fills until the operator stops the recording manually, the end recording date and time is reached or the battery runs down.
