RVR-52 Voltage, Pulse, Event Data Logger can measure and record input voltage from 0 to 6.5V.
You can choose to record the voltage measurement as the instantaneous value for the each recording interval span or as the average value for each recording interval span.
The average value for recording intervals under 15 seconds will be calculated as the average of the measurements from every 1 second. The average for intervals over 20 seconds will be calculated as the average of the measurements from every 2 seconds.

Pulse Measurement: 30 Counts per Second
RVR-52 Data Logger can measure up to 30 counts (30Hz) per second when the input voltage range is between 0-30V and there is a continuous pulse of more than 15 seconds. When measuring pulse, the largest number of counts for one recording interval is 32,000 counts. You can select from rising signal (Lo-Hi) or falling signal (Hi-Lo) and count when one or the other occurs.
Event Time Recording
RVR-52 Data Logger can record the time of any event; a rising (Lo to Hi) or falling (Hi to Lo) waveform that occurs for more than 1 second at an input voltage range of between 0-30V.
