DPM-3232

Digital DC Power Meter with Data logging capability

User Manual

Introduction

As a digital DC power meter, it measures the real time DC Voltage (5-60V), DC Current (0-60A), Watt, and it

also displays the Amp-hour, Watt-hour, Max. Watt, running time when Power Meter has been connected, the

maximum & minimum values of voltage and current during the measuring period. There is one pair of leads

for source input and another pair for load output, the power meter can either be powered by the input or the

output which ever has a minimum 5V DC. The Power Meter can also be powered by an external DC voltage

of 5 to 60V DC if DC voltage range of 0-60V is desired.

Once the Power Meter is powered up it starts to data logged Amp hour, Watt-hour, Max. & Min. Voltage &

Current values at selectable interval from 30 seconds to 3 minutes.

Up to 1,500 sets of data are stored in the Power Meter Memory (EEPROM) even when the Power Meter is

off power. The data can be retrieved by a PC using our optional Data adapter (USB type) and software

program.

The last set of data such as Ah, Wh, Max. current, Max. Watt, (and sometimes Max. and Min. Voltage) can

be displayed when only either the source or the load is connected to a dc source of 5 to 60V.

The power supply can either be mounted to the Snap-On bracket or any ferrous metal surface magnetically.

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 Startup screen does not appear, immediate remove the power sources.

f. It is a good practice to have either input or output terminal connected on the supplied terminal block to

prevent short circuited.

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 set of leads.

j. Do not exert pressure on the display to avoid damage to LCD display.

Operations and Displays Installation of the DC Power Meter. 1. First connect the leads to the side that provides the d.c. power to the meter and check for displays in the LCD. If no display in LCD then check for reverse polarity. 2. Last set of data will appear on the LCD, you can clear the old data by pressing the Reset Button twice, allow second press for about 5 seconds. 3. Connect the remaining leads to complete the installation of DC Power Meter. Set data logging time interval (with firmware version 1.

8. In case the setting is correct, then PRESS and HOLD “RESET” button to confirm the value. It will show OK to confirm sampling time setting. Then the DPM go to operation mode. DISPLAYS A. On the first power up the display shows the firmware version and factory preset data port mode. B. Measured Data Displays C. The Volts, Amp and Watt are continuously shown, all other data are shown in a cyclic order at about 3 second interval.

Display duration time after power ON Reset DPM There are two ways to clear all the previous stored data. 1. Press and hold the Reset button until the LCD display show “Press again 5 seconds to reset”, then release the Reset button quickly, press again and hold 5 seconds to delete the data. 2. Use the external power source connections see Fig.ONE connect the remote I/O black wire (marked RC at the DPM to source’s negative terminal for 3 seconds and then release. It will clear previous data record.) Fig.
