Product features and Scope of application:
1,BVIRBattery voltage internal resistance tester It is specially designed for the two battery(Including lead-acid, nickel cadmium, nickel hydrogen, lithium ion, lithium polymer battery.)High precision measuring instrument designedIt is a new instrument for measuring battery internal resistance by alternating current.,It can test the open circuit voltage and internal resistance of the battery.,Simple operation,Use reliability,Characteristics of high performance ratio,Simple operation.The maximum measurable internal resistance is 3000m ohm.It can measure battery internal resistance and battery voltage.In addition, we can test the sampling resistance of milliohm series.,Concopper resistance and so on,Widely used in scientific research institutions, production, two battery distribution.
supply voltage:DC9V Power voltage adapter(or 9V Battery)
Display voltage: DC 0~26.00V Display resolution 0.01V
Display resistance: 1.00 mOhm~3000.00mOhm Display resolution 1 mOhm
AC current frequency:1KHZ
Outer size:150 x 85 x 30 mm
off time:It will shut down automatically in about 3 minutes after the test is stopped.
This instrument features a battery equivalent to an active resistor,A constant AC current of 1000HZ, about 10mA for the tested battery.Then, a series of processes such as voltage sampling, rectification, filtering and so on are carried out.,The resistance in the battery can be accurately measured.The test uses the fixed zero method,Effective elimination of measurement error caused by contact resistance,Improve measurement accuracy.
Details of packing accessories:
Power Supply:DC 9V Power voltage adapter
Selection Four wire Kelvin test clip:1pcs or Four line test pen
Connect DC 9V Power voltage adapter(or 9V Battery),Press the Hold key to boot,Insert test clip,Clip two test clips together.Then hold down the HOLD key for 2 seconds,Clear zero,Because this product is a high-precision product, so after clearing off the impact of two test clips on the internal resistance of the target battery! Then test the two ends of the battery.
note:Because of the sensitivity of the test, several sets of data are repeated several times.
HOLD key operation:
1,Press the HOLD key once,The picture stays at a resistance level.Convenient reading.
2,Hold down the HOLD key for about 2 seconds,The current resistance is cleared.And shows zero resistance in the lower right corner.
3,Hold down the HOLD key for about 5 seconds, turn off.
This product allows the use of 9V rechargeable battery instead of 9V power supply voltage adapter for offline testing!
Matters needing attention:
1,If it is found that the internal resistance value of the test clip contact is different.,The reason is that the clamp contact is not good, or long-term use leads to the use of sandpaper knife to clean the negative electrode of the clamp can be.
2,Long time measurement of the same battery shows different internal resistance values.(Because the battery is equivalent to a small current discharge process, the internal resistance is different before and after discharge.)It is a normal phenomenon.
Causes and troubleshooting of failures:
1.The internal resistance of the battery is measured.,But the voltage is 0.00V:Check whether polarity of battery is reversed
2. Press HOLD key not to start :Check whether the power supply battery is in bad contact.
3. The internal resistance or resistance of the battery measured is incorrect.:Check whether the power supply battery is too low.,If the electricity is less than
30%, please charge.
