General PowMr 100/300A Voltmeter Meter Current Energy Meter Monitor

PZEM-015: Measuring Range 300A (use external shunt, can matched with 50A, 100A, 200A, 300A four kinds of shunt).Function description:Voltage:Measuring range: 0-200V. (when the test voltage is less than 8V, please use the independent power supply mode)Display format: less than 10V display as: 9.99Vless than 100V display as: 99.9Vgreater than 100V display as: 199VMinimum resolution:0.01VThe starting test voltage: 0.05VMeasurement accuracy:1%Current:Measuring range: 0-300A can set 50A, 100A, 200A,300A four range depend on the external shunt, the factory default is 100A.Display format: less than 1A display as: 999mA＜10A display as: 9.99A＜100A display as: 99.9A≥ 100A display as: 199AMinimum resolution: 1mAThe starting test current: 20mAMeasurement accuracy:1%Power:Measuring range: 0-60000WDisplay format: ＜ 10W display as: 9.99W＜ 100W display as: 99.9W＜ 1000W display as: 999W＜ 10000W display as: 9.99kW≥ 10000W display as: 19.9kwMinimum resolution: 0.01WThe starting test power: 0.2WMeasurement accuracy:1%Impedance:Impedance=Voltage/ CurrentMeasuring range: 0-1000ohmDisplay format: ＜ 100ohm display as: 99.9ohm≥ 100ohm display as: 999ohmWhen over the test range or the current is zero, it display "---"Minimum resolution: 0.1ohmMeasurement accuracy:1%Internal Resistance:Internal resistance= (Full voltage - Bring load voltage) / Bring load current, when the bring load voltage is larger than the maximum voltage, the internal resistance is zero.Measuring range: 0-999 milliohmDisplay format: 999 milliohm , when over the test range or the current is zero, it display "---".Minimum resolution: 1 milliohmMeasurement accuracy:1%Note:Before you test the internal resistance, you should preset the full voltage depend on the battery type, after it is fully charged youcan use it to test;if you do not fully charge it, you can set the battery without load voltage is the full voltage, then test; the internal resistance is not a fixed value, the more the battery discharged, the bigger the resistance.Capacity:Measuring range: 0-1000AHDisplay format:＜ 1AH display as: 999mAH＜ 10AH display as: 9.99AH＜ 100AH display as: 99.9AH＜ 1000AH display as: 999AHMinimum resolution: 1mAHMeasurement accuracy:1%Note:Battery capacity testing is a cumulative process of discharge current versus time, it need some time, the time is depend on the discharge current;Before you test the capacity, you should preset the full voltage and the cut-off voltage depend on the battery type, after it is fully charged you can use it to the discharge test; When the dump energy display blank, it means the discharge is over, this capacity display value is the battery's capacity.Dump energy:Dump energy is display via the battery symbol, totally 10 grids, every grid present 10% energy.Dump energy is calculated via the current battery voltage value, before test you should preset the full voltage and the cut-off voltagedepend on the battery type;every grid voltage = (the highest voltage - the lowest voltage) / 10.Accumulate energy consumption:Measuring range: 0-9999kWhDisplay format: ＜ 1kWh display as: 999Wh＜ 10kWh display as: 9.99kWh＜ 100kWh display as: 99.99kWh＜ 1000kWh display as: 999.99kWh≥ 1000kWh display as: 9999kWhOver the test range will become zero.Minimum resolution: 1WhMeasurement accuracy:1%Note: 1Wh=0.001kWh=0.001 KilowattRunning time:Measuring range: 0 ~ 999 hour (without load the time will not accumulate)Display format: 0:00:00 ~ 999:59:59Over the test range will become zero.Operating Instructions:Setting the full and cur-off voltagePackage included: 1 * DC Multimeter Battery Tester Monitor
