Security
MPI-535 meter is designed for performing check tests of protection against electric shock in
AC mains systems and recording mains systems parameters. The meter is used for performing
measurements and providing results to determine the level 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, familiarise yourself thoroughly with this manual
and observe the safety regulations and specifications provided by the manufacturer.
Any application that differs from those specified in this manual may result in a damage to the
device and constitute a source of danger for the user.
MPI-535 meters must be operated only by appropriately qualified personnel with relevant cer-
tificates authorising the personnel to perform works on electric systems. Unauthorized use of
the meter may result in its damage and may be a source of serious hazard to the user.
Using this manual does not exclude the need to comply with occupational health and safety
regulations and with other relevant fire regulations required during the performance of a par-
ticular type of work. Before starting the work with the device in special environments, e.g. po-
tentially fire-risk/explosive environment, it is necessary to consult it with the person responsi-
ble 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).
If the battery is discharged to a level preventing further measurements, the meter displays an
appropriate message and then turns off.
Battery spill and damage to the meter may occur if discharged batteries are left in the meter.
Before measurement, make sure that test leads are connected to appropriate measuring ter-
minals.
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 463 V RMS for 60 seconds.
Repairs may be performed only by an authorised service point.
NOTE!
Only standard and additional accessories for a given device should be used, as listed
in
section 8
. Using other accessories may cause damage to measuring terminals, in-
troduce additional measurement errors and create a risk for the user.
Due to continuous development of the meter’s software, the actual appearance of the
display, in case of some of the functions, may differ from the display presented in this
operating manual.
