1 Safety
The MIC-5010 and MIC-5005 meters are designed for performing check tests of protection against
electric shock in mains systems. The meters are used for making measurements and providing results
to determine safety of electrical installations. Therefore, in order to provide conditions for correct oper-
ation 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.
The MIC-5010 and MIC-5005 meters must be operated only by appropriately qualified personnel
with relevant certificates 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.
During measurements of insulation resistance, dangerous voltage up to 5 kV occurs at the ends of
test leads of the meter.
Before the measurement of insulation resistance you must be sure that tested object is disconnected
from the power supply.
During the measurement of insulation resistance do not disconnect test leads from the tested object
before the measurement is completed (see par. 3.1.1.); otherwise the capacitance of the object will
not be discharged, creating the risk of electric shock.
Using this manual does not exclude the need to comply with occupational health and safety regula-
tions 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/ex-
plosive 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 test leads 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 ambient
temperature (approximately 30 minutes).
One should remember that when the word appears on the display, it indicates insufficient
voltage of power supply and the need to recharge the batteries.
The symbols ErrX, where X is a number between 0 to 9, indicate incorrect operation of the meter.
If after restarting the device this situation is repeated - it indicates that the meter is damaged.
Before measurement, choose a correct measurement function and make sure that test leads are
connected to respective measuring terminals.
Do not power the meter from sources other than those listed in this manual.
The R
ISO
inputs of the meter are protected electronically from overload (e.g. due to having been
connected to a live circuit) up to 660V rms for 60 seconds.
Repairs may be performed only by an authorised service point.
