?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 0.001m¦¸ to 3¦¸ 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 0.001m¦¸ to 3.3¦¸ 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%¡À5dgt; V: 0.05%¡À5dgt? <br> Measuring Range: Resistance: 0.001m¦¸~3.3¦¸; 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.
