Overview: This meter is mainly used to test all kinds of battery's voltage, discharge current, discharge power, discharge impedance, internal resistance, capacity, dump energy, energy consumption and running for time, and display the measurement data through LCD screen. PZEM-013: Measuring Range 10A (Built-in Shunt) Function description Voltage Measuring range: 0-200V. (when the test voltage is 8V, please use the independent power supply mode) Voltage Minimum resolution:0.01V. Voltage The starting test voltage: 0.05V Voltage Measurement accuracy:1% Current Measuring range: 0-10A. (Type: PZEM-013) Current Minimum resolution: 1mA Current The starting test current: 10mA Current Measurement accuracy:1% Power Measuring range: 0-2000W Power Minimum resolution: 0.01W Power The starting test power: 0.1W Power Measurement accuracy:1% Impedance = Voltage/ Current Impedance Measuring range: 0-1000 (When over the test range or the current is zero, it display "---") Impedance Minimum resolution: 0.1 Impedance Measurement accuracy:1% 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. Internal Resistance Measuring range: 0-999m (Display format: 999m, when over the test range or the current is zero, it display "---".) Internal Resistance Minimum resolution: 1m Internal Resistance Measurement accuracy:1% (Note:Note: Before you test the internal resistance, you should preset the full voltage for depend on the battery type, after it is fully charged you can 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.) 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 voltage for depend on the battery type; every grid voltage = (the highest voltage the lowest voltage) / 10. Accumulate energy consumption Measuring range: 09999kWh (Over the test range will become zero.) Minimum resolution: 1Wh Measurement accuracy:1% (Note: 1Wh=0.001kWh=0.001 Kilowatt) Running for time Measuring range: 0 ~ 999 hour (without load the for time will not accumulate) Display format: 0:00:00 ~ 999:59:59 (Over the test range will become zero.) Working mode This meter has two modes: normal display mode and dormant mode. In normal display mode, short press the button to enter the dormant mode, in order to reduce the whole machine power consumption, the backlight and LCD display will be turned off in dormant mode. In dormant mode, short press the button will switch to the normal display mode. Note: The meter will stop all measurement functions in dormant mode, so please do not switch to dormant mode if normal measurement is performed. Power consumption Normal working state: 0.03-1.2 W Sleeping state: 0.5mW-0.5W (The power consumption is related to the test voltage value, the higher the voltage,the greater the power) Working temperature -20C ~ +60C.

Item color displayed in photos may be showing slightly different on your computer monitor since monitors are not calibrated same. Please allow 1-3mm slight deviation due to manual measurement. Thank you! Package included: 1 * for DC Multimeter 0-200V 0-10A Battery Tester Monitor
