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 G500/G1000 insulation and resistance measuring instru­ments allow for quick and efficient testing of protective measures
in accordance with DIN VDE 0100, ÖVE-EN 1 (Austria), SEV 3755
(Switzerland), and regulations specific to additional 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 bond­ing 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:

• Systems set-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 measure­ment 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.

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 stresses due to transport

• After long periods of storage under unfavorable conditions
(e.g. humidity, dust or extreme temperature)

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.

Ð Loosen both slotted screws for the battery compartment lid

on the back, and remove the lid.

Ð Remove 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.

Ð Push 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.

Ð Replace 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!

rLEAd – Offset Resistance for Low-Resistance Measurement
(

METRISO G500/G1000

)

Measurement cable ohmic resistance can be subtracted from the
measurement results automatically. Offset must be determined
and saved to memory via the rLEAd parameter to this end.

Ð Connect the measurement cables to the + and COM jacks.
Ð Short circuit the two test probes connected to the measure-

ment cables (including extension cables).

Ð Select the rLEAd parameter and acknowledge by pressing the

ENTER key. Select ZERO and acknowledge by pressing the
START key in order to trigger measurement of offset resistance:

 SET rlead

zero / Clear 

Low-resistance measurement as described in section 8.1 is con­ducted in both directions with automatic polarity reversal.

Note

If the test probes are not short circuited, the SHort LEAdS
prompt appears at the display.

The measurement results, i.e. the resistance of the two measure­ment cables, are subtracted from future low-resistance measure­ments as an offset value, and ZERO appears in the footer.

After selecting the CLEAr parameter and acknowledging by
pressing the ENTER key, you’re provided with the opportunity of
performing future measurements without using the offset. If this is
the case, ZERO is no longer displayed. In this case, measurement
cable resistance is included in the measurement.
