1 Safety
MIC-10k1 and MIC-5050 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.
MIC-10k1 and MIC-5050 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 10 kV (MIC-10k1) or 5 kV
(MIC-5050) occurs at the ends of test leads of the meter.
Before the measurement of insulation resistance you must be sure that tested object is discon-
nected from the power supply.
During the measurement of insulation resistance do not disconnect test leads from the tested ob-
ject before the measurement is completed (see par. 0); 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 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 ambi-
ent temperature (approximately 30 minutes).
Remember that BAT! message appearing on the display indicates insufficient voltage of power
supply and the need to recharge the batteries.
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.
RISO meter inputs are electronically protected against overloads (caused by e.g. connecting the
meter to a live circuit) up to 825 V for 60 seconds.
Repairs may be performed only by an authorised service point.
ATTENTION!
11 kV DC crocodile clips and probes are designed to work only on objects without voltage.
Note:
Due to continuous development of the meter’s software, the actual appearance of the dis-
play, in case of some of the functions, may slightly differ from the display presented in this
operating manual.

ATTENTION!
To display the correct battery discharge status, it is necessary to completely discharge
and then fully charge the battery, before starting the regular use of the meter.
Note:
An attempt to install drivers in 64-bit Windows 8 may result in displaying "Installation
failed" message.
Cause: Windows 8 by default blocks drivers without a digital signature.
Solution: Disable the driver signature enforcement in Windows.
