The AEMC L562 TRMS AC Voltage Current Data Logger is a two-channel Volt/Amp data logger. The choice of data storage modes and storage rates allows the operator to effortlessly configure the logger to optimize memory usage for the application at hand. Extended Recording Mode (XRMTM) and delayed start time are just two of the many application friendly features.

The Simple Logger® II Model L562 records TRMS at a rate of up to eight times per second. The measurement process is performed no more than eight times per second. TRMS calculations are performed on a single line cycle. This means that the input(s) are ignored between measurement intervals. The main advantage of the logger is its ability to perform a variety of recording tasks with easy and intuitive setup from a computer using DataView® software.

Analog information on the input is sampled and converted to a digital signal. This digital signal is processed and stored along with scale and time information. An optically isolated Universal Serial Bus (USB) port provides for the transfer of data from the instrument’s internal memory to the computer for analysis.

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 or 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.
