LCD after Switching on the Instrument

Please proceed as follows if the LCD display is not legible, i.e. too bright
or too dark, after switching on the test instrument:

1 Simultaneously press the two right-hand keys to delete the memory

which might be faulty.
2 Wait a few seconds to allow the display to be updated.
3 Readjust the contrast if necessary, see page 8.

Instructions for the Plug-on of the Following Accessory Adapters

• Interface converter IrDa-USB (Z501J)

• Temperature and humidity measuring adapter (Z541A)
➭ Connect the adapter with the IR interface of the test instrument, see

drawing on page 2: Insert the guide rail of the adapter in the opening

provided on top of the tester so that the adapter is located in the mid-

dle of the housing, resting on the two rubber cushions. Then push the

adapter down to ensure that it is safely fastened.

PC software WinProfi for communication with METRISO

®

C

The PS3 CD-ROM includes the software WinProfi with the following con­tent and functions:

• up-to-date test instrument software
– for loading another language
– for loading software version updates,

• Exchange of measured data between test instrument and PC

• Preparation, print-out and filing of test reports at the PC

The following interface converter is required for communication between
test instrument and PC:

– IrDa-USB Converter (Z501J): IrDa (tester) – USB (PC)

Data Backup

Measurement data and electrical circuit assignments can be safely stored
in a RAM as long as the associated battery supplies the required voltage.

We advise you to regularly transmit your stored data to a PC in order to
prevent potential loss of data in the test instrument. We assume no
responsibility for any data loss.

For data processing and management we recommend the following PC
software programs:

• PS3 (documentation, management, report generation and
monitoring of deadlines)

• PC.doc-WORD/EXCEL (report and list generation)

• PC.doc-ACCESS (test data management)

1 Applications

This instrument fulfills the requirements of the applicable European and
national EC guidelines. We confirm this with the CE marking. The relevant dec­laration of conformity can be obtained from GMC-I Messtechnik GmbH.
The METRISO®C test instrument allows for quick and efficient testing of
protective measures in accordance with DIN VDE 0100, ÖVE-EN 1 (Aus­tria), SEV 3755 (Switzerland) and other country specific regulations. The
instrument is equipped with a microprocessor and complies with IEC/
EN 61557/VDE 0413.
Part 1: General requirements
Part 2: Insulation resistance measuring instruments
Part 4: Measuring instruments for the measurement of resistance at

earth conductors, protective conductors and bonding
conductors

as well as requirements in accordance with VDE 0701-0702:
Repair, modification and testing of electrical devices

The test instrument is especially well suited for:

• Systems installation

• Initial start-up

• Periodic testing

• Troubleshooting in electrical systems
All required measurements can be performed for approval reports (e.g. for

ZVEH) with the help of a set consisting of the PROFiTEST

®

C and the

METRISO

®

C.
Measurement values can be transmitted to a PC for printing and archiving
via the integrated IR data interface at the METRISO

®

C. This is especially

important where product liability is concerned.

The following measurements and tests can be performed with the METRISO

®

C:

• Insulation resistance

• Low-value resistance

• Contact current

• Voltage and frequency

• Temperature and humidity (with accessories)

The following can also be measured with a shielded measurement cable:

• Conductivity of floor coverings for electrostatic discharge

2 Safety Features and Precautions

The METRISO®C electronic measuring and test instrument is manufac­tured and tested in accordance with safety regulations IEC/EN 61010-1/
VDE 0411-1 and EN 61557. If used for its intended purpose, the safety of
the operator and the instrument is assured.

Read the operating instructions carefully and thoroughly before using your
instrument, and observe all instructions included therein.

The measuring and test instrument may not be used:

• If the battery compartment cover has been removed

• If external damage is apparent

• With damaged connector cables or measuring adapters

• If it no longer functions flawlessly

• After excessive stress due to transport

• After lengthy periods of storage under unfavorable conditions
(e.g. humidity, dust, extreme temperatures)

• While the batteries are being charged

3 Initial Start-Up

3.1 Battery Test

Five battery symbol segments ranging from depleted to fully charged
continuously indicate the current battery level at the main menu.

3.2 Installing and Replacing Batteries
New batteries must be installed before initial start-up, or when only one

solid segment remains in the battery symbol.

Attention!

!

The instrument must be disconnected from the measuring circuit
(mains) at all poles before the battery compartment is opened.

Four 1.5 V baby cells in accordance with IEC LR14 are required for
operation of the METRISO

®

C. Use alkaline-manganese batteries only.
Rechargeable NiCd or NiMH batteries can be used as well. Be absolutely
sure to refer to chapter 13.2, page 26, regarding the charging cycle and
the charging adapter.
Always replace the batteries in complete sets.
Dispose of batteries in an environmentally sound fashion.
➭ Loosen the two slotted screws at the battery compartment cover on

the housing rear panel and remove the cover.

➭ Insert four 1.5 V baby cells making certain they are poled in

accordance with the symbols. Insert the two batteries which are half
covered by the housing first.

➭ Replace the cover and retighten the screws.

Attention!

!

The instrument may not be operated if the battery compartment
cover has not been installed and properly tightened!
