CAT III for measurements performed in the building installation, i.e. distribution boards, circuit breakers, wiring,
including cables, bus-bars, junction-boxes, switches, socket-outlet in the fixed installation, and equipment
for industrial use and some other equipment, for example, stationary motors with permanent connection to
the fixed installation.
CAT IV This category is for measurements performed at the service entrance i.e. at the source of the low voltage
installation (mains distribution, electricity transfer points to homes, electricity meters) or on power lines
(overhead or buried). This includes measurements before the service equipment overcurrent device.
3. Intended use
The device tester GT-6000 v2 is developed for electrical safety testing of portable appliances.
It is used for:
•
Portable appliances testing in accordance with DIN VDE 0701-0702, DGUV Regulation 3, ÖVE/ÖNORM E 8701,
NEN 3140
• Tripping time measurement of permanently installed (RCCB/RCD) and portable (RCCB/PRCD) circuit breakers
• Three-phase electrical devices testing (with the help of optional measurement adapters)
•
Voltage test on grounded sockets
• Cables, extension cables, cable distributions and IEC power cables testing
Tester GT-6000 v2 is characterized by the following features:
• Test results of GT-6000 v2 are compared with preset values of limits and based on that pass/fail information is
given to user. Preset values of limits and more information regarding test can be found in last versions of standards.
•
Default value of voltage for insulation resistance test is 500 V/DC (standard). If there is a need for lower voltage
(500 V/DC too high for DUT or voltage protection / surge arresters built-in), test voltage can be set to lower
value – 250 V/DC.
•
The differential current/direct measurement method is applied when GT-6000 v2 is supplied with 230 V/AC mains
voltage via the socket (the protective conductor current/contact current measurement is automatically provided).
• The alternative leakage current measurement method is applied when battery set inside GT-6000 v2 is used for
tests regarding the protective conductor current and contact current measurement.
• Approx. 2500 device tests can be performed by GT-6000 v2, with fully charged batteries.
