Bi-directional Digital DC Power Meter with built-in USB data logger & adapter
Bi-Directional DC Power Meter with built-in USB data logger & adapter.
The new DPM-3332 is an upgrade version of previous DPM series. It measures current in both direction, using a battery
as the reference, it measures the Charging and Discharging current.
DPM-3332 is a self contained with built in data adapter for data retrieval to PC* via USB port and for real time monitoring.
In addition to USB, it can be connected through optional Bluetooth* for Bluetooth model. The new EEPROM is increased
to 3,600 sets of data.
The direction of current is with reference to the receiving end (output) typically a battery. Current (charging) going to
battery is Positive (+) and current out of battery (discharging) is Negative(-).
The power meter is powered up by 5-60V dc from either side or an external USB power bank for extended measured dc
voltage range of 0-60V.
*Remark:
PC software, driver, software and Bluetooth manual can be downloaded from http://www.manson.com.hk/product/dpm-3332/

Precaution

a. Do not exceed 60A and 60V DC in application of DC Meter.
b. Do not apply 60A DC more than 5 second and non-repeatable within 60 second
c. This meter is designed and made for indoor use only.
d. Do not disassemble or attempt to repair the power meter.
e. If Start up screen does not appear, immediate remove all input and output connections power sources.
f. It is a good practice to have either input or output terminal connected on the supplied terminal block to prevent
possible short circuiting
g. Double check on the correct polarity. If either input or output connection is in wrong polarity, there is no display on
LCD.
h. Damage to the Power Meter may result if wrong polarity power is applied.
i. Never short leads connected to either input or output set of leads.
j. Do not exert pressure on the display to avoid damage to LCD display.

: Constant displays: V, A, and W.
: Two sets of values for most parameters, the positive value means current going into the
battery  and the negative value means current coming out of the battery .
Parameters : Time period in use , Ah (Amp Hour) , WH(Watt Hour) , Vp (max voltage), Ap
(max.current), Wp( max.Watt), Vm (min.Voltage), Negative : -Ah , -WH, -AP,-Wp back to
Time period in use.
Freeze Scrolling display : Hold and release of any scrolling display by quick press of RESET
button .
