1.1 Features of the logger
Congratulations on purchasing the Accsense VersaLog series data loggers! These portable
battery powered data loggers allow recording information and saving measurements to a 4MB
flash memory for later retrieval.
The internal lithium battery provides up to 10 years of instantaneous logging operation when
sampling at interval of one minute.
Accsense VersaLog data logger can be manipulated by VersaLog SiteView Windows software
for data downloading, logging management, and property configuration. It has both TTL-
compatible serial port and USB interface for different communications requirements.
Accsense VersaLog data loggers feature a wide sampling interval range from 20 milliseconds to
12 hours, providing an alternative to data acquisition devices and paper chart recorders.
Accsense VersaLog data loggers provide alarm outputs controlled by the low and high
programmable alarm thresholds of each enabled channel. The alarm control outputs can be used
to turn on/off external alarm devices such as strobe lights, sirens or alarm telephone diallers.
Accsense VersaLog data loggers also have an excitation control output used to switch the power
supply of the external transducer/transmitter.
Accsense VersaLog data loggers contain one internal thermistor channel, and seven external
process signal channels. The 16-bit analog-to-digital converter makes the measurements more
precise and accurate.
Accsense VersaLog data loggers also have a rugged, splash-resistant aluminum enclosure, and
internal electronics are protected against moisture ingress by conformal coating.
