Megger CM500 Multifunction Insulation Tester
The MEGGER® CM500 Multifunction Installation Tester is a
compact product that combines all the functions required to fully test
Domestic, Commercial and Industrial fixed wiring, in accordance with
International Standards. The CM500 is the first Installation Tester with
a non-tripping Loop Test guaranteed not to trip any RCD rated 30 mA or above.
Its memory and storage capability offers all data to display, download to a PC
and a unique on-site print facility.
Tests in accordance with International Standards and National
Wiring Regulations including BS7671 (16th edition wiring regulations) and Euro
Standard EN61557.
Test lead resistances can be nulled and a continuity buzzer is
incorporated for rapid identification of open and short circuits. Settable
automatic polarity reversal and result averaging.
Loop tests are performed to a resolution of 0,01 . with direct
display of PEFC and PSCC.
A unique low current Loop Test with 0,1. resolution for
testing circuits protected by an RCD rated at 30 mA or above, without tripping
the RCD, including the newer electronic ones.
Auto-ranging earth resistance function enables measurement of
earth electrode resistance on TT systems. Verification of the correct
operation of RCDs rated between 10 mA and 1000 mA with trip timing up to 2000
ms. A ramp test indicate actual trip current to aid in fault diagnosis
and variable test current function enables the testing of programmable and
specialist devices.
Upon connection to the mains supply the polarity and voltage
are displayed to show correct wiring of the socket under test and warn of live
voltages. Supply frequency is indicated at the touch of a button.
Approximately 750 different results may be saved into internal
memory for use later on. Stored results may be recalled to the CM500
display to enable reviewing and facilitate the manual recording and completion
of test reports and certificates.
Test results may be printed directly on site by simply
connecting an appropriate serial printer to the RS232 port.
A standard RS232 serial port enables test results to be
downloaded to a PC for later use. The ultimate solution is provided with the
use of AVO® PowerSuite™ for Windows™.
Meets or exceeds the requirements of EN61010-1 Category III
480 V (max) phase-phase.
