The AEMC SDL A302 Sentinel Data Logger is a three-channel current recording devices with Alkaline batteries and is designed for recording AC current up to 3000AAC through three integral 24" flexible current probes for each input.
Real-time display of waveforms and harmonics is available with the DataView® software, which is included. Programmable storage rate and storage modes, combined with simple one button operation, make this a versatile and easy-to-use data logger, perfect for a variety of applications.
Line tracking is performed such that 64 samples over one line cycle are taken. Frequency tracking is performed over the range of ±3Hz around the nominal line frequency (50 or 60Hz). Measurements are calculated from these 64 samples for all input channels. The Sentinel® records RMS values for each of the inputs at a rate
of up to four times per second. Measurements for each channel are taken sequentially. RMS calculations from the 64 samples are performed on each single line cycle measured for each input. DC measurements are also on all voltage models and probe dependent on current models.
The main advantage of the Sentinel® logger is its ability to perform a variety of recording tasks with easy and intuitive setup from a computer using the DataView® software, which is included. 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 facilitates the transfer of data from internal memory to the computer for analysis.
Three LEDs on the front panel (red, yellow and green) indicate recording and memory status at a glance. User selectable storage rate, recording length and recording modes are provided.
