Featuring an acclaimed easy-to-read display and a high resolution input, the MicroAMP Meter takes the APM into a
wide range of new applications, where accurate DC current measurement is required.

The APM MicroAMP is ideal for DC current measurement applications in marine, leisure, material handling, and industrial
applications such as power supplies, load banks and charging systems. The programmable scale and custom annunciators
mean users can tailor the meter to display their critical parameters exactly how they want. Dynamic backlighting, in
conjunction with setpoints, means operators are visually alerted when a parameter is out of range while the two outputs can
be used to connect the APM to other systems in the process, meaning the MicroAMP is much more than just a display.
