1.1. PRELIMINARY INSTRUCTIONS
CAUTION
The instrument must be connected to
a power socket with
grounded PE termina
l. If this is not assured, the instrument will
display “
PE DISCONNECTED, SWITCH OFF NOW
” message and
will not perform any measurement
x
The instruction manual contains information and references, necessary for safe
operation and maintenance of the instrument. Prior to using the instrument, the
user is kindly requested to thoroughly read the instruction manual and comply
with it in all sections
x
Failure to read the instruction manual or to comply with the warnings and
references contained herein can result in serious bodily injury or instrument
damage
x
In order to avoid electrical shock, the valid safety and national regulations
regarding excessive contact voltages must receive utmost attention when working
with voltages exceeding 60 V DC or 50 V (25 V) RMS AC. The value in brackets
is valid for limited ranges (as for example medicine)
x
The operator is recommended to respect the usual safety regulations aimed at
protecting against dangerous currents and protecting the instrument against
improper use
x
This instrument has been designed for use in environments of pollution degree 2
x
It can be used for tests on electrical installations of overvoltage category III, 300V
maximum voltage to earth
x
Do not effect measurements on circuit exceeding the specified voltage limits
x
Only the original test leads supplied along with the instrument guarantee
compliance with the safety standards in force. They must be in good
conditions and, if necessary, replaced with identical ones
x
Do not take measurements under environmental conditions exceeding the limits
indicated in this manual
x
Before connecting the test probes to the installation make sure that the right
function is selected
x
The instrument may only be used in dry and clean environments. Dirt and
humidity reduce insulation resistance and may lead to electrical shocks, in
particular for high voltages
x
Never use the instrument in precipitation such as dew or rain. In case of
condensation due to temperature jumps, the instrument may not be used
x
Start any test series by earth bond resistance measurement
x
At earth bond resistance, insulation resistance and dielectric measurements unit
under test must be voltage-free. If necessary check the unit is voltage-free i.e. by
using a voltage tester
x
When modifying the instrument, the operational safety is no longer ensured.
