Description
The most visible, easy to use, programmable panel meter on the market. The APM Micro Meter measures DC current in the 0 to 200µA range with 0.1% accuracy, purpose-built for specialised low-current applications where standard amp meters lack the resolution. It combines the instant readability of an analog meter with the precision of a digital meter: a 40-segment curved bar graph gives an immediate visual indication, while four 12mm digits provide a precise numeric readout.
This variant uses a positive (light-background) LCD, optimised for readability in bright ambient light or direct sunlight.
The colour-changing backlight can be programmed to alert operators when a monitored value is too high or too low, reducing the risk of equipment failure and improving efficiency. Free APM configuration software allows full customisation of scale and range, with 16 preset configurations selectable via back-panel switches and 20-point non-linearisation scaling for non-linear sensors. It is fitted with two configurable outputs (digital open collector or analog 4–20mA), supporting up to 10 independent alarm setpoints with a configurable digital output delay (0.5–120 seconds). Optional Modbus RTU communication and remote monitoring via Trumeter Cloud and the APM Gateway are also supported, making it easy to fold this meter into a wider monitoring or alarm system.
Typical applications include electronics and telecommunications testing, environmental monitoring, laboratory instrumentation, circuit testing, sensor calibration, and other low-power electronics work.
