1 Applications
This instrument fulfills all requirements of applicable European and
national EC directives. We confirm this with the CE mark. The rel-
evant declaration of conformity can be obtained from GMC-I
Messtechnik GmbH.
The METRISO XTRA insulation and resistance measuring instru-
ment allows for quick and efficient testing of protective measures
in accordance with DIN VDE 0100, ÖVE-EN 1 (Austria), SEV 1000
(Switzerland), and regulations specific to other countries as well.
The device is equipped with a microprocessor and complies with
IEC/EN 61557 / VDE 0413 regulations:
Part 1: General requirements
Part 2: Insulation resistance
Part 4: Resistance of earth connection, protective conductors
and equipotential bonding
Part 10: Electrical safety in low-voltage systems up to 1000 V
AC and 1500 V DC – Equipment for testing, measuring
or monitoring of protective measures
As well as requirements per VDE 0701-0702:
Repair, modification and testing of electrical devices
The test instrument is especially well suited for:
•Systems setup
• Initial start-up
• Periodic testing
• Troubleshooting in electrical systems
The following measurements and tests can be performed with the
insulation measuring instrument:
• Insulation resistance
• Low-resistance
• Voltage
The following can also be tested by using a shielded measure-
ment cable:
• Floor covering electrostatic discharge capability
1.1 Optional Z550A Remote Control
The optional remote control with triggering key on the test probe
and a key for illuminating the measuring point makes it possible to
use the measuring instrument at difficult to access places.
For safety reasons, a predefined voltage is only applied to the test
probes for as long as the triggering key is held depressed.
The start key on the test instrument should be used instead of
remote control for triggering polarization and absorption index
measurements, because these two measurements involve com-
plete measuring cycles.
