observed:
Before you proceed to operate the meter, acquaint yourself thoroughly with the present manual
and observe the safety regulations and specifications determined by the producer.
The MRU-200 / MRU-200-GPS meter has been designed for the purpose of measurements of
earth connection and equipotential bonding, ground resistivity, as well as clamps current meas-
urements. 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.
The device must be operated solely by appropriately qualified personnel with relevant certificates
to realize measurements of electric installation. Operation of the meter realized 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 the following:
A damaged meter which is completely or partially out of order,
A meter with damaged test leads insulation,
A meter stored for an excessive period of time in disadvantageous conditions (e.g. exces-
sive humidity).
If the meter has been transferred from a cool to a warm environment of
a high level of relative humidity, do not realize measurements until the meter has
been warmed up to the ambient temperature (approximately 30 minutes).
Before measurements may commence, make sure the test leads are connected to the appropri-
ate 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.
The meter’s inputs are electronically protected from power surge, as a result for example, of ac-
cidental connection to the power supply source:
- for all input combinations
– up to 276 V for 30 seconds.
Repairs may be realized solely by an authorized service point.
The device complies with the following norms; EN 61010-1 and EN 61557-1, -4, -5.
