Bidirectional measurement
DPM can measure the current in both directions or just one direction.
In typical applications using a battery bank as a base reference, the DPM data logs the discharging current (negative current) & discharging Ah or the charging current (positive current) & charging Ah.

This unique capability brings in related both the negative and the positive ampere hour, peak current & etc. values.
The support of bidirectional current measurement reduces the complication of wiring and several meters when in-and-out current measurement is needed.
Built-in Bluetooth for monitoring & download by smartphones
Each standard the DPM-3332 is capable of real-time monitoring of charging parameters and data download by using smartphones with installed Apps.
Large internal data storage
The extra large data bank allows for storing more data. It can store 30 hours of data at 30 sec sampling rate or 60 hours at 60 sec or 180 hours at 180 sec sampling rate. There are 20 groups of data with selective sampling rates available, each time the DPM is powered up a new group with a selective sample rate is formed.
Build-in USB for PC connectivity
This self-contained DC Power Meter has a built-in data adapter to download logged data directly to a PC via USB.
Downloading data is simple with only one connection to the micro USB port of the power meter and the USB port of the PC with the provided USB cable.

Typical Applications
