Note

The indicated current values of 30 mA and 3 mA for switch
positions 7 M and 70 M are merely guidance values.
Usually, the capacitance of the connector cables is suffi­ciniently high to ensure that the current values actually mea­sured exceed considerably that level and can therefore not be
used as reference values.
This applies particularly for the test instruments of the SECUT­EST

1 Applications

Attention!

!

The adapter is used for testing measuring accuracy of test
instruments in accordance with DIN VDE 0701-0702 and
DIN EN 62353 (VDE 0751-1). As a rule, these instruments
must be tested once each year as set forth by accident pre­vention regulation BGV A3 (formerly BGV A2 and/or VBG4), as
well as for certification in accordance with the ISO 9000 qual­ity standard.

All measuring ranges for tests required in accordance with
DIN VDE 0701-0702 such as protective conductor resistance,
insulation resistance, equivalent leakage current and residual
and/or contact current must be tested.

2 Safety Features and Precautions

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 SECU-cal 10 calibration adapter is manufactured and
tested in accordance with safety regulations IEC 61010-1 /
EN 61010-1 / VDE 0411-1.

If used for its intended purpose, safety of the user and of the
device is assured.

Read the operating instructions completely and carefully
before using the adapter, and follow all instructions included
therein. Observe the operating instructions included with the
test instrument to be tested as well.

The calibration adapter may only be used for testing
test instruments in accordance with DIN VDE 0404!
Under no circumstances may the adapter be used
in electrical systems!

outlet (test socket or mains outlet) for the perfor­mance of tests with line voltage, set the rotary
switch at the calibration adapter to the DI/I position.

Non-observance may result in:

• Destruction of the adapter

• Charging of the protective conductor with impermissible

fault currents of up to 8.25 mA

• Tripping of 10 mA RCCBs

If the “NETZ/MAINS” and “POLARITÄT/POLARITY” lamps light
up simultaneously during the test with mains voltage in rotary
switch position DI/I, the polarity of the calibration adapter must
be reversed before measurement is performed. Only the
“NETZ/MAINS” lamp may remain illuminated. Non-obser­vance may result in erroneous measurements.

Only test instruments with a protective conductor test
current of no greater than 1 A may be connected to the
calibration adapter. Greater current values result in
destruction of the adapter.

The device is not equipped with overcurrent or
excessive temperature protection.
Under no circumstances may the device’s load
capacities be exceeded, because this may damage
the device or reduce its level of accuracy.
