2.1 Description
The Simple Logger
®
II Bluetooth Series of loggers are four channel
recording devices powered by alkaline batteries.
Frequency tracking is performed such that 64 samples over one line cycle
are taken. Frequency tracking is performed around the nominal frequency
of 50/60Hz. Harmonic measurements are calculated from these 64 sam
-
ples (harmonics are only available from the
Simple
Logger
II
Control
Panel within the DataView
®
software).
The Simple Logger
®
II records at a rate of up to eight times per second.
Samples are taken at a user defined storage rate. This means that the
input(s) are ignored between measurement intervals.
The SLII’s battery operation allows operation without the need for external
power. A series of front panel LEDs provide a quick status of the logger’s
state, memory usage and low battery indication.
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, Bluetooth communication and long battery life.
Analog information on the input is sampled and converted to a digital
value. This digital signal is processed and stored along with scale and
time information. An integrated Bluetooth module provides for the transfer
of data from the instrument’s internal memory to the computer for analysis.
