DPM 3221 Digital DC Power Meter with Data logging capability User Manual Introduction The DPM 3221 digital DC Power Meter measures and displays in real time DC Voltage 0 60V DC Current 0 200A with a 200A 50mV external shunt and Watts 0 12000W It also displays Amp hour Watt hour maximum or peak Watts running time since Power Meter start up and minimum and maximum values of voltage and current during the measuring period The power for the meter can either be from the source or the load whichever has a minimum 5V DC available only voltages between 5V and 60V can be measured when powered in this way The Power Meter can also be powered by an external DC voltage of 5 to 60VDC which then allows a voltage measurement range of 0 60V Once the Power Meter is powered up it starts to display and log the Voltage and Current It also displays Wattage Amp hours Watt hours Max amp Min Voltage and Current and peak Watts The logged data values are recorded at 3 minute intervals Up to 1 500 sets of data can be stored in the Power Meter s Memory EEPROM so even when the Power Meter is powered down data is retained The data can be retrieved by a PC using the optional Data Adapter DPA 3051 and a software program provided Unless reset the last set of data values Ah Wh peak Current peak Watts and sometimes min and peak Voltage is retained and displayed when the DM 3221 is powered up A new group of data up to 20 is created each tim
