2.1 Introduction
Thank you for choosing AT528/AT528L Handheld AC Ohmmeter.
AT528/AT528L handheld AC Ohmmeter adopts high-performance 32-bit ARM processor.
It is a meter with wide resistance measurement range from 0.01mΩ to 2kΩ (AT528) and
DC voltage range from 1.000V to 50.00V.
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 a
voltmeter.
The AT528/AT528L completes with comparator function and external interface utilizing
the principles of the AC 4-terminal method that gives priority to line use and offers high
speed, high accuracy and high resolution.
AT528 is also equipped with Mini-USB to RS232 interface to apply to remote control, data
acquisition and analysis.
