Product presentation

Compact, the CA 757 tester is a measuring and control device equipped with the essential functions required by electricians.


Lightweight and easy to handle, the CA 757 has an IP 54-rated housing that protects against dust and water splashes and can withstand a fall from 2 metres.
Its large backlit display makes it easy to read the values.


The test probes are removable and easily replaceable.
They can be stored together with the cord inside the device.


Ergonomic and indispensable for testing and maintenance operations, the CA 757 also allows you to work in complete safety:

  • voltage protection up to 6 kV (electric shock)
  • protection up to 1000 V for all functions
  • indication of dangerous voltage
  • Automatic shutdown of the device after 10 minutes
  • Double insulation 600 V CAT III

    The CA 757 complies with the new IEC 61010-2-033 standard for multimeters.


    Easy to use, the CA 757 automatically recognises AC and DC voltages, as well as continuity, resistance, diodes and capacitance.


    It detects live conductors without contact.


    The CA 757 tester comes with a flexible MiniFlex current sensor that allows current measurements up to 300 A AC, even in hard-to-reach places.

Main features:

  • DC voltage: 3 mV DC to 1000 V DC
  • AC voltage: 100 mVAC to 1000 VAC
  • Current: 500 mA to 300 A (with MiniFlex sensor supplied)
  • Resistance: 0.3 Ω to 30 MΩ
  • Continuity sound for R ≤ 30 Ω
  • Capacitance: from 400 pF to 30 mF
  • Diode test
  • Non-contact voltage detection
  • 600 V CAT III
