The new C.A 652x & C.A 653x insulation testers are compact, lightweight and simple to use, offering greater comfort for users:

– Casing designed with 600V CAT IV safety and IP54 / IK04 protection for a comfortable grip in total safety with easy access to the TEST button, even when the user is wearing safety gloves

–  Magnetic stand for fixing the product on a metal surface so that users have their hands free when measuring and reading the result

–  Wide backlit screen with double digital display and logarithmic bargraphsecondary display showing the actual test voltage, the test current and the timer value, in addition to the value measured

–  Remote control with torch for error-free identification of the points of measurement, even in environments with poor lighting

Insulation tests:


This new range is equipped with various insulation test voltages ranging from 10 V to 1 kV. The dynamic range for insulation measurement extends up to 200 GΩ, remaining compliant with the IEC 61557 standard up to 2 GΩ.

In addition to the manual mode, there are also new insulation test modes such as Lock modeTimer mode and calculation of the PI & DARratios.

Continuity tests:

The continuity test function, which complies with the IEC 61557 standard (200 mA current), is enhanced on certain models with a 20 mA test current, with the advantage of prolonging battery life in normal use. This function is equipped with activefuselessprotection if a voltage is present.

Measurement adaptability:

On most of the models in the C.A 652X & C.A 653x range, you can activate an alarm threshold, choosing between 2 fixed thresholds and 1 customizable threshold for each measurement.

Furthermore, the ΔREL function can be used to display the measurements which differ from a reference measurement. The display shows the value of the variation and the percentage in relation to the reference.

Other functions:

DMM functions are available with measurement of  voltage up to 700 Vfrequency up to 800 Hzresistance up to 999 kΩ and capacitance up to 10 µF.

Easy operation:

Analysis of the measurements is facilitated by storage of 300 measurements on the instrument. The memory capacity is extended to 1,300 locations for the versions with Bluetooth® communication. The Megohmmeter Transfer (MEG) software module, delivered as standard with the communicating versions, allows remote test activation with real-time graphical display and transfer of the stored measurements onto a PC. The values are then displayed by type of measurement.

The DataView® software suite (option) generates customized measurement reports which may include the location of the site and the contact details of the operator.
