10.1 General
The extensive accessories available for our measuring
instruments are checked for compliance with currently valid safety
regulations at regular intervals, and are expanded as required for
new applications. Currently up-to-date accessories which are
suitable for your measuring instrument are listed at the following
web address along with photo, order number, description and,
depending upon the scope of the respective accessory, data
sheet and operating instructions: www.gossenmetrawatt.de

10.2 Technical Data for Measurement Cables
(included: KS17-2 safety cable set)
Electrical Safety
* Exception METRAHIT ESPECIAL: 600 V
Ambient Conditions (EN 61010-031)
Tempera t u re –2 0C ... + 50C
Relative humidity max. 80%
Pollution degree 2
Application KS17-2
Attention!
!
In conformity with standard DIN EN 61010-031, mea-
surements in an environment according to measuring
category III and IV may only be performed with the safety
cap applied to the test probe of the measurement cable
(Exception:
METRAHIT ESPECIAL is only approved for mea-
suring category 600 V CAT II).
For establishing contact in 4 mm jacks you have to remove the
safety cap by levering out the snap lock of the safety cap with an-
other sharp object (e.g. the second test probe).
10.3 NA X-TRA Power Pack (not included)
Use only the power pack from GMC-I Messtechnik GmbH in
combination with your instrument. This assures operator safety by
means of an extremely well insulated cable, and safe electrical
isolation (nominal secondary ratings: 5 V / 600 mA). Installed
batteries are disconnected electronically if the power pack is
used, and need not be removed from the instrument.
