Dadmatrac electronics [p] ltd. Manufactures with battery voltage logger.
It is designed to log 7 channels of single ended dc voltage, from 0 to 20 volts. Salient features are as follows:
1. ambient temperature is also logged alongwith at each lap, measurement is done through a sensor mounted inside the logger.
2. at the channel voltage input there is a reverse polarity connection protection also.
3. all the data in the logger is stored in its nvram, thus ensuring data retention even in the absence of power.
4. in case the data logging process is incomplete, then the logger resumes logging from the lap no. Where it left.
5. a multiple number of such loggers may be used simultaneously, because each logger has its unique id no. For identification.
