3. C Meter This meter is designed and made for indoor use only Do not disassemble or attempt to repair the power meter If Startup screen does not appear immediate remove the power sources It is a good practice to have either input or output terminal connected on the supplied terminal block to prevent short circuited Double check on the correct polarity If either input or output connection is in wrong polarity there is no display on LCD g Damage to the Power Meter may result if wrong polarity power is applied h Never short leads connected to either set of leads i Do not exert pressure on the display to avoid damage to LCD display Dapp Controls and Indicators k Arrow Mark to show Input Source leads 2 LCD Display Constant displays V A and W Scrolling displays Amp Hour Watt Hour and Max Watt Hour Max amp Min Current Voltage and total time Power Meter connected 3 Arrow Mark to show Output Load leads 4 Scrolling display Any one of the scrolling displays can be stopped at your desired display and released by one quick press of the Reset button 9 7 8 9 Input Source leads External Power Jack for external power source 5 60V DC to extend measured voltage to 0 60V DC from 5 60V Pin imprint 5 GND RC 5V Positive 5V to 60V positive of external DC source GND Negative of external DC source RC This is for deleting stored data see Fig ONE Phone Jack for connectio
4. 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 30 A Watt and it also displays the Amp hour Watt hour Max Watt running time when Power Meter has been connected the maximum amp 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 amp Min Voltage amp Current values at 3 minutes interval 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 Future development for RS 232 or RS 485 communication modes is planned 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 Do not exceed 30A and 60V DC in application of D
