This document describes the specification of the PZEM-013/015 DC multifunction battery tester, 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 time, and display the measurement data through LCD screen.
PZEM-013: Measuring Range 10A (Built-in Shunt)
PZEM-015: Measuring Range 300A (use external shunt, can matched with 50A, 100A, 200A, 300A four kinds of shunt).
Function description
Voltage
Range 0 200v ( when test under 8V, please use the independent power supply mode)
The starting test voltage: 0.05V
Accuracy: 1%
Display format
<10V display as 9.99V
<100V display as 99.9V
>100V display as 199V
Current
Range: 0 10A (Type: PZEM-013)
0-300A(Type: PZEM-015) can set 50A 100A 200A 300A , 4 range depend on the external shunt, 100A in default
The starting test voltage: 10mA (Type: PZEM-013)
20mA(Type: PZEM-015)
Accuracy: 1%
Display format
<1A display as 999mA
<10A display as 9.99A
<100A display as 99.9A
>100A display as 199A
Power
Range: 0 2000W (Type: PZEM-013)
0-60000W(Type: PZEM-015)
The starting test voltage: 0.1W (Type: PZEM-013)
0.2W(Type: PZEM-015)
Accuracy: 1%
Display format
<10W display as 9.99W
<100W display as 99.9W
<1000W display as 999W
<10000W display as 9.99kW
>10000W display as 19.9kW
Inpedance=Voltage/Current
Range 0 100Ω
Accuracy: 1%
Display format
<100Ω display as 99.9Ω
>100Ω display as 199Ω
Internal Resistance=(full voltage-bring load voltage)/bring load voltage, when the bring load voltage is larger than the maximum voltage, the internal voltage is zero.
Range 0 999mΩ
Accuracy: 1%
Display format: 999mΩ, when over the test range or the current is zero, it display ---
Note: before you test the internal resistance, you should preset the full voltage depend on the battery type, after it is full charged, you can use it to test.
If it was not full charged, you can set the battery without load voltage to the full voltage, then test.
The internal resistance is not a fixed value, the more the battery discharged, the bigger resistance.
Capacity
Range 0 1000AH
Accuracy: 1%
Display format
<1AH display as 999mAH
<10AH display as 9.99AH
<100AH display as 99.9AH
<1000AH display as 999AH
SOC
SOC is display via the battery symbol, totally 10 grids, every grid present 10% energy
SOC is calculated via the current battery voltage value, before test, you should preset the full voltage and cut-off voltage depend on the battery type.
Every grid voltage=(the highest voltage - the lowest voltage )/10
Energy
Range 0 19999kWh
Accuracy: 1%
Display format
<1kWh display as 999kWh
<10kWh display as 9.99kWh
<100kWh display as 99.99kWh
<1000kWh display as 999.99AH
>1000kWh display as 9999AH
Over the test range will become zero
Running time
Range 0 10999hour(without load the time will not accumulate)
Display format: 0:00:00 999:59
Over the test range will become zero
