AT525 Storage Battery Meter is an instrument that can test battery AC internal resistance and DC voltage online. It adopts high-performance 32bits ARM processor. It is a meter with wide resistance measurement range from 0.001mΩ to 3Ω and DC voltage range from 0V to 60V. The instrument features an m-ohm and V mode that allows simultaneous measurement and comparison of battery internal resistance and open-circuit voltage. This meter is highly suitable for battery inspection lines as one unit can act as both a low-resistance meter and voltmeter.   <br> <br> <strong>Features:</strong> <br> Adopts high-performance 32bits processor， measuring battery AC internal resistance and DC voltage online. <br> Built-in large capacity 8.4V 2200mAh rechargeable lithium battery(included) for long time use. <br> Handheld in design and high quality， portable for use. <br> Wide resistance measurement range from 0.001mΩ to 3.3Ω and DC voltage range from 0V to 60V. <br> Large digital LCD screen for display， Max. display: 3300(resistance)， 6000(voltage). <br> Features an m-ohm and V mode that allows simultaneous measurement and comparison of battery internal resistance and open-circuit voltage. <br> Completes with comparator function and external interface， high speed， accuracy and high resolution. <br> Can output comparison /decision results for sorting components into resistance HIGH-IN-LOW bins and voltage HIGH-IN-LOW bins. <br> Can also directly measure UPS batteries while working online. <br> Equipped with Mini-USB interface to apply to remote control， data acquisition and analysis. <br> Equipped with USB-Disk interface， can store 500 sets test values. <br> Automatic power off， auto zero-adjust for each range.  <br> Suitable for measuring all kinds of batteries' resistance and DC voltage， such as lithium batteries， lead-acid batteries， button cell batteries， etc. <br> <br> <strong>Specifications:</strong> <br> Measuring Parameters: AC Resistance， DC Voltage  <br> Accuracy: R: 0.5%±5dgt; V: 0.05%±5dgt  <br> Measuring Range: Resistance: 0.001mΩ~3.3Ω; Voltage: 0.0001V～60.000V <br> Signal Source: AC: 1KHz， Open-circuit Voltage: &lt;30mV， Current: &lt;15mA  <br> Range: Automatic， Manual， Nominal 4 Ranges  <br> Speed: 1 Time/Second <br> Result Display: ABS(Absolute Deviation)/Relative Deviation/SEQ(Sequence) <br> Max.
