APM-M1-APO is an APM M1 versatile panel meter configurable to measure voltage, current, or frequency, and is compatible with 12-24V AC/DC power supplies. The unique display combines analog-style readability with digital precision, featuring a large 4-digit readout, a 40-segment bar graph, and a color-changing backlight for immediate condition feedback. Customize settings such as scale, range, alarms, messaging, and backlight color via the APM software for tailored performance. The M1 meter also includes two outputs, configurable as either digital (open collector) or analog (4-20mA), to facilitate communication with other devices or systems. The negative LCD display, with color-changing figures on a black background, is optimized for darker environments. For a simple yet powerful remote monitoring platform, the APM M1 connects to Trumeter Cloud via the optional APM IoT Gateway, offering data recording along with email and optional SMS alerts.
