Battery Data Recorder
Alternative of the Pico M
The BTM D is an inexpensive data logging device designed primarily for battery capacity test and performance data collection. The main design goal is to keep the system as simple as possbile and make the installation as quick as possible.
The BTM D features logging of voltages (2 jars or jar and its strap), AC ripple and a jar temperature at the clip-point. Data logging function is triggered by significant voltage change. The trigger levels are user programmable. When data logging is activated, additional data records are also stored based on elapsed time. Timer period is also programmable.
The BTM D devices can store data of several discharge tests, total of 1200 records. Unlike other monitoring systems, this device is stand alone, does not require external power supply, complex wire-harness nor any data communication during logging period.
The BTM D devices can be installed in an arbitrary order. A single device installation takes only a few seconds, involving connecting two or three aligator clips to the jar posts.
- Simple clip-on, no excessive wiring required
- Small size, light weight, installed in seconds
- Fast sampling rate, independent of the jar count in the string
- No additional hardware required
- Large data storage capacity
- Two jars or a jar and its strap measurement options
- Universal operation from 16V dc down to 0.9V dc; well suited for Ni-Cd batteries
Collected data is transferred to a computer or a tablet via USB cable, after devices have been removed from the battery at a later time.
