Functions illustration

Thanks to wide functionality, special design and compact size ACM-2025 can accomplish a wide range of electrical, service and domestic tasks:

1. Inductive non-contact True RMS AC and DC current measurements (e.g.: circuit breaker load current).

Thanks to the True RMS feature the instrument is capable to measure non-sinusoidal signals.
DCA ZERO button helps to clear the display in DC measurement mode.
Compact size of open clamp "jaws" makes it easier to work in hard-to-reach places and wire bundles.

2. Current consumption peak value measurements (DATA HOLD and PEAK HOLD buttons fix current or peak values (800 ms) on the display).

This allows to optimize the load on the individual outlet power lines in the room and identify the cause of the sudden breaker tripping or fuse blowing.

3. AC Voltage measurements (e.g.: at the feeder switchboard breaker poles).

The voltage tester function is built-in: just connect the standard test leads (included).

4. DC voltage measurements (e.g.: laptop adapter DC output connector).

DC voltage device diagnostic with automatic polarity indicator enriches the field of use.

5. Resistance measurements (e.g.: PCB components).

Circuits and individual components (including SMD) resistance measurements.

6. Continuity test (e.g.: AC/DC laptop adapter earth core continuity test; board circuits testing).

Audible alarm is triggered automatically in resistance measurement mode if the value is less than 3 Ohms.

La pinza amperimtrica AKTACOM ACM-2025 utiliza el tenedor sensitivo anterior para obtener una medicin rpida. No es necesario abrir las mandbulas en comparacin con las pinzas tradicionales.

Este detector puede medir corrientes sin contacto tan solo al aproximar el tenedor delantero, cuenta con una slida carcasa irrompible resistente al fuego con una proteccin de goma que la hace muy manejable para el usuario. Por su forma de tenedor no requiere espacio para abrir las mandbulas en zonas muy reducidas o de difcil acceso. Todas las funciones vienen con proteccin por sobrecarga, lo que ofrece un mximo de seguridad para el usuario. Podr usar el detector de corriente para conductores con un dimetro de hasta 19/32” (15mm). Es una herramienta muy til para el servicio tcnico o uso personal. Ha sido construido con circuitos lgicos LSI que le otorgan una alta fiabilidad y durabilidad.


1. Pantalla digital LCD (12.2mm), 3 posiciones con un mximo de 1999 dgitos.
2. Proteccin electrnica de sobrecarga.
3. Funcin de memorizacin de valores (Data Hold) y valor extremo (Peak Hold).
4. RMS verdadero para voltaje y corriente Alterna.
5. Carcasa doble moldeada.
6. Medicin de resistencia hasta 200 ohm y control de continuidad con zumbador.
7. Corriente alterna hasta 200 A.
8. Tensin hasta 600 V CA/CD.
9. Funcin de punto cero DCA.
10. Dimetro mximo del conductor: 19/32 (15mm).
11. Indicador de voltaje de batera bajo.

Botn de mantencin de valores

Para congelar la lectura del medidor LCD, presione el botn HOLD de datos. Presione el botn HOLD de nuevo para volver al funcionamiento normal.


  • Asegrese que la batera CD 9V est conectada con la polaridad correcta.
  • No exceda el mximo de voltaje aconsejado.
  • Coloque las pinzas roja y negra en la entrada correcta antes de medir.
  • Siempre coloque el botn conmutador en OFF para apagar el equipo.
