Amp Meter
A digital amp meter for measuring direct AC & DC current up to 5A
The APM Amp Meter is a digital amp meter for measuring AC & DC direct current up to 5A to 1% accuracy. For applications including control panels and power supplies.
Benefits include:
- Auto-detects AC or DC input
- Measures 5A direct
- 1% accuracy (with up to 50mA fluctuation)
- 20 point non-linearization scaling (for non-linear sensors)
- 10 alarm setpoints & configurable digital output delay
- Remote monitoring with Trumeter Cloud and APM Gateway
If you are using a shunt and measuring DC current, we recommend using our APM Shunt Meter >

Why Choose the APM Amp Meter
The APM Amp Meter is a versatile ammeter designed for a wide range of current measuring and monitoring applications. It auto-detects AC or DC currents up to 5A with 1% accuracy, making it suitable for various equipment and measurement needs. Alternative meters for specific applications include:
- APM CT Meter: measures AC currents from 0 – 10,000A with 0.5% accuracy
- APM Shunt Meter: measures DC currents from 0 – 1,000mV with 0.1% accuracy
The unique display combines the instant readability of an analog meter with the precision and functionality of a digital meter. Get quick recognition and precise functionality for the easiest to use and easiest to read panel meter available.
Easy-to-Read Display Technology
The APM Amp Meter’s display combines the best of both digital and analog amp meters, making it easy to read even in challenging conditions.
- Two Contrast Options: Order the positive display for bright sunlight, or the high-contrast negative display for indoors.
- 40-Segment Curved Bar Graph: Get an immediate visual indication of parameters.
- Large Readout: The APM Amp meter features four 12mm [0.47″] digits for clear and accurate readings.
- Adjustable Brightness: Change the backlight brightness to suit different environments.
- Wide Viewing Angle: Operators can read the meter from a range of positions.
User Configurable Digital Ammeter
The APM Amp Meter is highly customizable using the APM configuration software. The easy-to-use, free software allows you to tailor the meter to your specific needs.
- Color Changing Backlight: Customize color and intensity, with flashing or static alerts for specific conditions.
- Customizable Scale & Range: Adjust offset, gain, linear scale, and min/max range with 20-point non-linear scaling.
- 16 Pre-set Configurations: Use position switches on the back of the meter to select pre-set standard configurations without software.
- 10 Independent Alarms: Set conditions and actions to meet your requirements.
- Messaging Area: Display custom messages and annunciators.
- Digital Output Delays: Set delays from 0.5 to 120 seconds.
Remote Monitoring
Every APM comes with a free lifetime subscription to Trumeter Cloud so you can remotely monitor the status of your systems. Just add on our plug-and-play APM Gateway to get:
- Customizable alarm conditions and thresholds for notifications
- Unlimited email notifications, plus options to add instant text messages
- Exportable data stored securely in the Cloud
Output & Communications
The APM Amp Meter comes standard with two outputs to communicate with other systems: 1 digital (open collector) or 1 analog (4-20mA). In certain circumstances we can customize the APM Amp Meter with Modbus RTU for further communications.
