Safe and easy to use
Applications 
The C.A 755 and C.A 757 multitesters meet the speci c needs of professionals working on Low-Voltage electrical
installations. Their numerous automated functions help to prevent the usual handling errors. With their 600 V CAT III safety
and their compliance with the IEC 61010-2-033 standard, they are intended for electricians, heating engineers, mechanics,
maintenance technicians, etc.
They offer exceptional safety for testers:
double insulation
protection up to 6 kV for voltage measurements (electric shocks)
protection up to 1,000 V for continuity testing and resistance or capacitance measurements
protection against dust with their IP54 casing
No-contact voltage detection
and hazardous voltage indication are both available.
In addition to testing the electrical power supply or switching systems,
checking wired connections, monitoring consumption (current) and
verifying the operation of an electrical appliance or installation, these new

testers can also be used to troubleshoot failures or faults
and test electronic components.
The C.A 755 & C.A 757 are effective in all circumstances:
Troubleshooting on distribution switchboards with
the possibility of identifying the phase and neutral
without tripping the RCDs.
DC and AC voltage measurements to check the
different voltages present on the terminals.
Audible continuity test
DC voltage measurements for preventive
maintenance on backup batteries.
Resistance measurement: identification of the
motor windings and checking of the resistors.
Current measurement on residential switchboards
and junction boxes: the C.A 757’s MiniFlex flexible
sensors mean current measurements are always easy.
Diode tests for maintenance of DC power supply
systems and checking of bridge rectifiers.
