Description:
Four lines 1KhzAC sine battery internal resistance meter 0.01 Milliohm---200Euro range. Measurable lead acid, Lithium ion, Lithium polymer, Lithium iron phosphate, alkaline, dry battery, ni-mh, Nickel cadmium, Button, battery, etc.
Short press the power on button to turn on the low resistance function, measure 0.30-0.50 Milliohm internal resistance.
The instrument is equipped with lithium battery, It's rechargeable.
Low resistance function: This function can be improved 5A curacy of internal resistance below milliohm. High capacity lithium batteries are becoming more and more popular, This function is very important. Moreover, the low resistance function of the instrument improves the speed, Almost as fast as turning off the low resistance function. The figure below shows the measurement of this instrument 0.5 Precision of high capacity lithium battery with milliohm internal resistance.
The accessories of this instrument are probes, Kelvin clip, 4-wire shelf available. The probe is cheap, Cylindrical cells can be measured. The clip is most suitable for batteries with polar ears, The clamp must be open when measuring, Both arms of the clamp contact the same electrode at the same time.
Specification:
Size: 134 x 70 x 25mm
Internal resistance measurement (Automatic range switching or manual range switching)
Precision format: ±(Accuracy percentage+Least significant digit)
Range | Minimum resolution | Accuracy |
