1 Safety
MPI-530-IT meter is designed for performing check tests of protection against electric shock in
AC mains systems. The meter is used for making measurements and providing results to determine
safety of electrical installations. Therefore, in order to provide conditions for correct operation and
accuracy of obtained results, the following recommendations must be observed:
 Before you proceed to operate the meter, acquaint yourself thoroughly with the present manual
and observe the safety regulations and specifications provided by the producer.
 Any application that differs from those specified in the present manual may result in a damage to
the device and constitute a source of danger for the user.
 MPI-530-IT meters must be operated only by appropriately qualified personnel with relevant certif-
icates authorising the personnel to perform works on electric systems. Operating the meter by
unauthorised personnel may result in damage to the device and constitute a source of danger for
the user.
 Using this manual does not exclude the need to comply with occupational health and safety regu-
lations and with other relevant fire regulations required during the performance of a particular type
of work. Before starting the work with the device in special environments, e.g. potentially fire-
risk/explosive environment, it is necessary to consult it with the person responsible for health and
safety.
 It is unacceptable to operate:
 a damaged meter which is completely or partially out of order,
 a meter with damaged insulation,
 a meter stored for an excessive period of time in disadvantageous conditions (e.g. excessive
humidity). If the meter has been transferred from a cool to a warm environment with a high
level of relative humidity, do not start measurements until the meter is warmed up to the am-
bient temperature (approximately 30 minutes).
 Displayed BAT! symbol indicates insufficient voltage of power supply and the need to charge the
accumulator or replace batteries. All measurements except voltage measurements for Z and
RCD functions are blocked.
 Battery spill and damage to the meter may occur if discharged batteries are left in the meter.
 Before measurements may commence, make sure the leads are connected to the appropriate
measurement sockets.
 Do not operate a meter with an open or incorrectly closed battery (accumulator) compartment or
power it from other sources than those specified in the present manual.
 R
ISO
meter inputs are electronically protected against overloads (caused by e.g. connecting the
meter to a live circuit) up to 440V rms for 60 seconds.
 Repairs may be performed only by an authorised service point.
ATTENTION!
Only standard and additional accessories for a given device should be used, as listed
in the "Equipment" section. Using other accessories may cause damage to measuring
terminals, introduce additional measurement uncertainty and create a risk for the user.
Note:
Due to continuous development of the meter’s software, the actual appearance of the
display, in case of some of the functions, may slightly differ from the display presented
in this operating manual.
