1 Applications
These instruments fulfills all requirements of applicable European
and national EC directives. We confirm this with the CE mark. The
relevant declaration of conformity can be obtained from GMC-I
Messtechnik GmbH.
METRISO INTRO/BASE/TECH insulation and resistance measur-
ing instruments allow for quick and efficient testing of protective
measures in accordance with DIN VDE 0100, ÖVE-EN 1 (Austria),
NIV/NIN SEV 1000 (Switzerland), and regulations specific to addi-
tional countries.
The device is equipped with a microprocessor and complies with
IEC/EN 61557 / VDE 0413 regulations:
Part 1: General requirements
Part 2: Insulation resistance measuring instruments
Part 4: Instruments for the measurement of resistance at
earthing conductors, protective conductors and bond-
ing conductors
Part 10: Combined measuring equipment for testing, measuring
or monitoring protective measures
As well as requirements per VDE 0701-0702:
Repair, modification and inspection of electrical appliances.
The test instrument is especially well suited for:
•Systemsset-up
• Initial start-up
• Periodic testing
• Troubleshooting in electrical systems
The following measurements and tests can be performed with the
insulation measuring instruments:
• Insulation resistance
• Low-resistance
• Voltage
The following can also be tested by using a shielded measure-
ment cable:
• Floor covering electrostatic discharge capability

2 Safety Features and Precautions
The electronic measuring and test instrument is manufactured
and tested in accordance with safety regulations IEC/EN 61010-1
/ VDE 0411-1 and EN 61557.
When used for its intended purpose,
safety of the operator, as well as that of the instrument, is assured.
Read the operating instructions thoroughly and carefully before using
your instrument. Follow all instructions contained therein. Make sure that
the operating instructions are available to all users of the instrument.
Tests may only be executed by a qualified electrician.
The measuring and test instrument may not be placed into service:
• If the battery compartment lid has been removed
• If external damage is apparent
• If connector cable or measuring adapters are damaged
• If the instrument no longer functions flawlessly
• After extraordinary damage due to transport
• After long periods of storage under unfavorable conditions
(e.g. humidity, dust or extreme temperature)
Opening of Equipment / Repair
The equipment may be opened only by authorized service per-
sonnel to ensure the safe and correct operation of the equipment
and to keep the warranty valid.
Even original spare parts may be installed only by authorized ser-
vice personnel.
In case the equipment was opened by unauthorized personnel,
no warranty regarding personal safety, measurement accuracy,
conformity with applicable safety measures or any consequential
damage is granted by the manufacturer.

3 Initial Start-Up
3.1 Battery test
Four different battery symbols, ranging from fully depleted to fully
charged, continuously indicate the momentary charge level in the
upper left-hand corner of the display
If battery voltage has fallen below the allowable lower
limit, the pictograph shown at the right appears. The
instrument does not function if the batteries have been depleted
excessively, and no display appears.
3.2 Installing or Replacing Batteries
New batteries must be inserted for initial start-up, or if only one
filled segment remains in the battery symbol.
Attention!
!
Before opening the battery compartment (see page 5 for
location), disconnect the instrument from the measuring
circuit (mains) at all poles.
Eight 1.5 V size AA batteries in accordance with IEC LR 6 are
required for operation of the insulation measuring instrument. Use
new alkaline manganese batteries only.
Rechargeable NiCd or NiMH batteries may also be used. These
can only be recharged externally. We recommend rechargeable
NiMH batteries.
Always replace batteries in complete sets.
Dispose of batteries in an environmentally sound fashion.
ÐLoosen both slotted screws for the battery compartment lid
on the back, and remove the lid.
ÐRemove the battery holder and insert eight 1.5 V size AA bat-
teries with correct polarity in accordance with the symbols.
Attention!
!
Make sure that all of the batteries are inserted with correct
polarity. If just one battery is inserted with reversed polar-
ity, it will not be recognized by the instrument and may
result in leakage from the batteries.
ÐPush the battery holder into the battery compartment such
that the battery holder’s contacts touch the contact springs at
the bottom of the battery compartment (see drawing on
page 3).
If the battery holder is not inserted as specified, the instrument
cannot be supplied with power.
ÐReplace the battery compartment lid and retighten the
screws.
Attention!
!
The instrument may only be placed into service if the
battery compartment lid is securely fastened!
