SmartReader Plus 4 Logger Application Notes (pdf)
Fast Sampling with Battery Pack or External 120 Volt Power Supply
For sampling rates faster than once every 8 seconds, the Smart Reader Plus data loggers require the use of an external 120 volt power supply (#PS-201) or fast sampling battery pack (#BP-101).
The fast sampling battery pack has replaceable "AAA" batteries and 8" (20cm) cable attached, with a male stereo jack on the end. The stereo jack is plugged into the communication port on the Smart Reader Plus data logger.
The 120 Volt Power Supply is required when network length is greater than 50' , more than 3 loggers are on the network, or for sampling rates greater than 8 seconds on the SmartReader Plus Loggers.
