Features
- Digital LCD display, easy to read the measurement result. With backlight, it makes it easy to read in low light areas.
- Adopt 4-wire method which helps to ensure the accuracy of the measured value.
- True four line 1Khz AC sinusoidal battery internal resistance instrument 0.00001 ohm – 200 ohm range.
- Test range up to 200 ohms with a minimum resolution of 0.01 milliohms and less than 5 milliohms.
- Press HOLD to enable the ZR function to measure internal resistance as low as 0.30–0.50 milliohms.
- It is applicable for measurement of internal resistances of Lithium-ion, Pb, Li-Ion, Ni-MH, Li-Pol, LiFePO4, Ni-H2, Ni-Cd cells or assembled battery.
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, 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 100 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.
Could you tell me how to adjust YR1035+ to zero? There is also a 0.0X mΩ resistance between the two Kelvin clips?
There is a wiring sequence for the direct short circuit of the Test line. The clamping sequence is red line, black line, white line, white line. Only when the probe test line contacts the same metal surface can it be the minimum value. The minimum value is generally not zero, but does not affect the measurement accuracy. No processing is required. (The machines are all calibrated before shipment, and no zero adjustment is required normally.)
Can YR1035+ measure large single lithium iron phosphate battery?
Lithium iron phosphate is generally recommended to measure batteries within 100 ampere hours. The internal resistance of the battery above 100 ampere hours is generally lower than the recommended measurement of 0.3 mΩ or more. This battery can be measured with internal resistance below 100V and above 0.3~0.5 mΩ.
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.
What are the advantages of YR1035+?
The most important thing is that the YR1035+ is a 4-wire measurement, which avoids the resistance of the test wire and contact resistance with the battery. This enables YR1035+ to be stable in the range of 0.48mΩ~0.52 mΩ when measuring resistance as small as 0.5 mΩ (this measurement accuracy is actually higher than the nominal accuracy). In addition, the measured speed can be stable at 2~3 seconds in the automatic range and 1~2 seconds in the fixed range.
Others have other auxiliary functions. Up to 100V can be measured, which is convenient to measure some battery packs.
