A modus operandi ensuring the added value of a continuously evolving organization.
SAFETY FIRST
Electrical measuring instruments, prior still to fulfilling their purpose,
must consider operator safety as a basic requirement in terms of protection
against temporary overvoltages that may arise due to the presence of complex
electrical loads, short-circuit situations, lightening strikes, etc.
To this end, the international standard IEC 61010-1, Harmonised in Europe as EN 61010-1, has set out specific requirements that must be satisfied by electrical equipment designed for LV measurements (<1000VAC), creating four “Overvoltage Categories” that define the level of protection against the voltage transients of each instrument, depending on its distance from the power source.
Instruments belonging to the highest category require greater internal protection insofar as they can operate close to the source.

TEST INSTRUMENTS
In residential installations, the CEI 64-8 standard requires certain checks in order to certify that the installation has been developed in a workmanlike manner. In addition to the usual voltage and current testers, HT ITALIA also offers simple, portable instruments for classic ground, RCD and insulation measurements.
JUPITER / M75L / EASYTEST HT ITALIA’s Jupiter, a long-time leader in multifunctional system testing, is a revolutionary multimeter able to test 30 mA RCDs and perform earth tests, that is, carry out the essential checks required for all residential installations. The M75L model also includes insulation testing up to 500V, while EASYTEST can effectively carry out all the necessary 64-8 tests, including the possibility to save the results and generate a report via the supplied software.
STARTERKIT A single kit complete with a current clamp and digital tester for measuring the typical parameters in these types of electrical installations, specifically voltage, current and resistance. HT20: portable voltage tester.
HT77C: RCDs suddenly tripping due to leakage currents is a common occurrence. This instrument is able to measure these very small currents and get to the root cause, which are often household appliances with insulation problems.
