W rnings rel ted to s fety – gener l inform tion
 This document is not supplement to the Instruction m nu l! Ple se find the oper ting
m nu l s PDF file on the enclosed CD-ROM.
 If the test equipment is used in m nner not specified in this user m nu l, the protection
provided by the equipment could be imp ired!
 Re d this user m nu l c refully, otherwise the use of the instrument m y be d ngerous
for the oper tor, the instrument or for the equipment under test!
 Do not use the instrument or ny of the ccessories if ny d m ge is noticed!
 Consider ll gener lly known prec utions in order to void risk of electric shock while
de ling with h z rdous volt ges!
 If the fuse F1 h s blown, ple se follow the instructions of this oper ting m nu l to
repl ce it! Only use fuse complying with the specific tion (see ch pter 7.1) s
repl cement.
If one of the fuses F2 or F3 h s blown, the device must not be used nymore. In this c se,
the device must be sent to BENNING for inspection nd rep ir.
 Do not use the instrument in AC supply systems with volt ges higher th n 550 V AC.
 Service, rep irs or djustment of instruments nd ccessories is only llowed to be
c rried out by competent uthorized personnel!
 Ple se use st nd rd or option l BENNING ccessories only which re v il ble from

W rnings rel ted to s fety – me surements
Insul tion resist nce
 Insulation resistance measurement should only be performed on de-energized objects!
 Do not touch the test object during the measurement or before it is fully discharged! Risk of
electric shock!
 When an insulation resistance measurement has been performed on a capacitive object,
automatic discharge may not be done immediately! The warning message and the actual
voltage (Udisch) are displayed during discharge until voltage drops below 30 V.
 Do not connect test terminals to external voltage higher than 600 V (AC or DC) in order not to
damage the test instrument!
Low-imped nce resist nce/continuity test
 Low-impedance resistance measurements/ continuity tests should only be performed on de-
energized objects!
 Parallel loops may influence on test results.
Testing PE termin l
 If the phase voltage is detected at the protective conductor connection P , immediately stop all
measurements and ensure that the fault of the installation will be eliminated.
W rnings rel ted to s fety – b tteries/ stor ge b tteries nd fuses
 Disconnect all test cables / accessories from the tester and from the installation and switch the
tester off before opening the cover of the battery / fuse compartment. Dangerous voltages
may be applied to the interior of the tester!
 Please make sure that the storage batteries are inserted correctly, because otherwise the tester
is not ready for operation and the storage batteries will discharge.
 Do not recharge alkaline battery cells!
 The storage batteries must be charged only by means of the charger included in the scope of

1.9 B tteries nd fuses
B tteries
W rning:
 Disconnect all test cables / accessories from the tester and from the installation and
switch the tester off before opening the cover of the battery / fuse compartment.
Dangerous voltages might occur inside the tester!
 Use alkaline batteries or rechargeable NiMh batteries (storage batteries) of the size AA
only! Do not recharge alkaline batteries!
 Please make sure that the batteries / storage batteries are inserted with correct polarity,
because otherwise the tester cannot be operated and the batteries / storage batteries will
discharge.
 If the tester will not be used for a longer period of time, remove all batteries / storage
batteries from the battery compartment in order to protect the tester against leakage of
the batteries / storage batteries.
The rechargeable NiMh batteries (storage batteries) will be recharged automatically as soon as the
charger is connected to the charging socket. An integrated protective circuit controls the charging
process.
