Features
1. Voltage resistance with the screen at the same time measurement, measurement quickly and steadily.
2. The minimum resolution of up to 0.01 milliohms, easy-to-test large capacity, high discharge rate low resistance battery. The range can be 200 ohms and can be measured by button batteries, 9V laminated batteries, and other low-capacity small current high internal resistance batteries.
3. Voltage, and internal resistance test function, respectively, with manual automatic range function. The automatic range switch is stable and quick, the measurement shows 4 times per second update, and the basic can be locked in about 1S time range stable display. HOLD function to help you lock the display, more convenient for reading.
4. Using dot matrix LCD screen. Size font combination, which clearly shows the measurement results, but also displays rich content.
5. 2 kinds of display modes. Normal mode with the screen displays resistance and voltage, and sorting mode shows the internal resistance voltage and the level of battery classification and counting.
6. Has a three-level battery rating detection. By setting the voltage resistance rating, the battery can be grouped.
7. Built-in charging management circuit. And can be set to 200mA and 400mA with two charging currents.
8. Energy saving function. Can be set 5 – 60min shutdown delay. No operation and input, the ultra-delayed automatic shutdown. Can be set to a 5-30min delay into low power mode.
Differences Between YR1030+ and YR1035+
YR1030+ Maximum voltage: 28V
YR1035+ Maximum voltage: 100V
YR1035+ has higher voltage accuracy and resolution than YR1030+. The internal resistance accuracy is the same.
Application
designed for measuring batteries of type Pb, Li-Ion, Ni-MH, Li-Pol, LiFePO4, Ni-H2, and Ni-Cd, as well as alkaline and dry cells, button cells, resistors, etc.
NOTE:
It is forbidden to enter an AC signal and a DC voltage greater than 28 V.
FAQs
Voltage value jitter when not measured after starting up
Under the condition of no test after starting up, it is normal that the voltage has a numerical jitter. The value is a random value, meaningless, and has no influence on the measurement results.
The internal resistance below 0.3 mΩ cannot be measured, can it?
It is not impossible to measure, and the reading error is large. For example, 1 mΩ error plus or minus 0.03 m Ω , if it is 0.2 m Ω error plus or minus 0.05 m Ω, so more than 0.3 m Ω is recommended. The measured value of 0.05 mΩ is sometimes very accurate, but the uncertainty will make the reference of little significance.
To measure the internal resistance of the 18650 battery, should it be fully charged or not?
If you want to get a general idea, you can test directly. To be precise, if it‘s a new battery, test it on a full charge. Old batteries are tested after they have been drained. But under normal conditions, the change in internal resistance is very small. The better the battery‘s internal resistance, the less it is affected by the amount of charge.
Is the instrument measuring time positive and negative? Will the connection be damaged?
Connect opposite have no influence, divide positive and negative pole. As long as it doesn‘t exceed 100V.
The figures change quickly and cannot be measured.
The test line is not in good contact with the battery, there is strong interference around or the battery is charging and discharging. Normal use will not appear jump.
Is it necessary to take off the battery line to test one of the multiple connections of electric cars? Or can you just measure it?
As long as it is not in startup, or charging, you can directly test one section.
Is it OK to measure the battery pack?
As long as the total measured voltage is less than 100V. However, the resistance of the connecting line between the batteries is often greater than the internal resistance of the battery, so the series measurement cannot accurately measure the internal resistance. It is best to measure the battery poles directly.
Can I measure the internal resistance of capacitance?
The internal resistance value of approximate capacitance.
