MIC-10k1 MIC-5050 USER MANUAL
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 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. 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
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. 3.2.1); 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
regulations 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 firerisk/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 ambient 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 display, 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 and Windows 10 may
result in displaying “Installation failed” message. Cause: Windows by default
blocks drivers without a digital signature. Solution: Disable the driver
signature enforcement in Windows.

Notes:
Measurements
The result of the latest measurement is remembered by the meter until the next measurement is started or the measuring function is changed by means of the rotary switch. The result of the latest measurement is displayed on the screen for 20 seconds. Then it may be recalled by pressing ENTER, also after the meter is turned off and turned back on again.
Note: If a message shown below appears:
Meter temperature is too high! Measurement impossible!
turn the meter off and put it in a place that guarantees cooling.
WARNING: During a measurement, switching of the range switch is forbidden
because it may damage the meter and pose a threat to the user.
3.1 Diagnostics performed by the meter limits
The meter is able to assess whether the measurement result is within
acceptable limits. The user may set a limit, i.e. maximum or minimum value,
which should not be exceeded by the result. For measurements of insulation
resistance, the set limit is the minimum value, whereas for measurements of
continuity of protective conductors and equipotential bonding- it is the
maximum value.
The limits are activated globally in the main menu (Section 2.1.5). When the
function of setting limits is activated, the display, in its lower left
corner, shows the symbols with the following meaning: – : the result is
correct, it is within the set limits, – : the result is incorrect, it is
outside the set limits,
The method for setting limits is described in the chapters describing the
measurement data. In DD, SV functions and in after-burning it is not
possible to set limits.
3.2 Measurement of insulation resistance
WARNING: The tested object must not be live.
Note: During measurement, especially of high resistances, make sure that test
leads do not touch each other and probes (crocodile clips), because such a
contact may cause the flow of surface currents resulting in additional error
in measurement results.
Inverter output current is limited at 1,2 mA, 3 mA or 6 mA level. Activation
of the current limit is indicated by a continuous beep. The measurement result
is correct, but on the test terminals the test voltage is lower than voltage
selected before the measurement. The current limitation occurs in the first
phase of the measurement due to charging the capacity of the tested object.

3.2.2 Three-lead measurement
In order to eliminate the influence of surface resistance in transformers,
cables, etc. the threelead measurement is used, but do not connect the current
measuring test lead RISO- to large ground conductors. For example: at the
measurement of inter-winding resistance of a transformer, G socket of the
meter should
be connected to the transformer tank;
when measuring the insulation resistance between one of the windings and the
transformer’s tank, connect G socket of the meter to the second winding:
24
MIC-10k1 MIC-5050 USER MANUAL
when measuring insulation resistance between one of the cable conductors and
the cable jacket, the effect of surface resistances (important in difficult
weather conditions) is eliminated by connecting a piece of metal foil
insulating the tested conductor with G socket of the meter;
The same shall apply when measuring the resistance between two conductors of
the cable, attaching to G terminal other conductors that do not take part in
the measurement. at the measurement of insulation resistance of a high voltage
circuit breaker, G socket of the
meter should be connected to the terminals’ insulators of the breaker;

3.2.5 Dielectric Discharge Indicator DD
In the dielectric discharge test the discharge current is measured after 60
seconds from the end of measurement (charging) of the insulation. The DD is a
value characterising the insulation quality independent from the test voltage.
The measurement operates in the following way: first the insulation is charged
with a current for a set period. If this voltage is not equal to the set
voltage the object is not charged and the meter abandons the measurement
procedure after 20 seconds. After the charging and polarisation is complete,
the only current flowing through the insulation is the leakage current. Then
the insulation is discharged and the total dielectric discharge current starts
to flow through the insulation. Initially this current is the sum of the
capacity discharge current, which fades quickly and the absorption current.
The leakage current is negligible, because there is no test voltage.
After 1 minute from closing the circuit the current is measured. The DD value
is calculated using the formula:
DD I1min U pr C
where: I1min current measured 1 minute after closing the circuit [nA], Upr
test voltage [V], C capacitance [F].

3.5 Determining the length of the tested cable
Based on the electrical capacity of the tested object, the device enables the
user to determine the length of the tested cable. For this purpose before
starting the measurement it is necessary to obtain data on the object’s
parameters (e.g. from the manufacturer’s catalogue sheet).
Each cable is marked at 1-metre intervals with the following data: name of the
manufacturer, cable type, rated voltage, number of conductors and cross-
section of each of them.
For example, the photograph shows a cable of YHAKXS 1×240 RMC/50 12/20 kV
type.
Find this cable in the catalogue sheet of its manufacturer. The parameter you
search for is unit capacity.
Its value should be converted to nanofarads per kilometre (nF/km) the value
is entered into the meter in field CX.
In this case the obtained value is 0.3 µF/km = 300 nF/km.
Now you can configure the meter. Use F2 button to select CX.

6.5 General principles for using Li-Ion rechargeable batteries
– Store the half-charged battery pack in a plastic container placed in a dry,
cool and well ventilated place and protect them from direct sunlight. The
battery pack may be damaged if stored when fully discharged. The ambient
temperature for prolonged storage should be maintained within the range of
5°C…25°C. – Charge the batteries in a cool, well-ventilated place at a
temperature of 10°C … 28°C. Modern fast chargers detect both too low and too
high temperature of rechargeable batteries and react to the situation
adequately. Too low temperature should prevent starting the process of
charging, which might irreparably damage rechargeable batteries. The increase
in temperature of the battery pack may cause electrolyte leakage and even its
ignition or explosion. – Do not exceed the charging current, as it may result
in ignition or “swelling” of the battery pack. “Swollen” battery pack must not
be used. – Do not charge or use the batteries in extreme temperatures. Extreme
temperatures reduce the lifetime of rechargeable batteries. Always observe the
rated operating temperature. Do not dispose the battery pack into fire. – Li-
Ion cells are sensitive to mechanical damage. This kind of damage may cause
its permanent damage and thus ignition or explosion. Any interference in the
structure of Li-ion battery pack may cause its damage. This may result in the
ignition or explosion. A short-circuit of the battery poles “+” and “-” may
permanently damage the battery pack or even cause its fire or explosion. – Do
not immerse Li-Ion battery in liquids and do not store in humid conditions. –
If the electrolyte contained in the Lithium-Ion battery pack, contacts eyes or
skin, immediately rinse the affected place with plenty of water and consult a
doctor. Protect the battery against unauthorised persons and children. – When
you notice any changes in the Lithium-Ion battery pack (e.g. changes in
colour, swelling, excessive temperature), stop using the battery pack. Li-Ion
batteries that are mechanically damaged, overcharged or excessively discharged
are not suitable for use. – Any misuse of the battery may cause its permanent
damage. This may result in the ignition. The seller and the manufacturer shall
not be liable for any damages resulting from improper handling Li-Ion battery
pack.
6.6 General principles for using gel (lead) rechargeable batteries
– Store the rechargeable batteries in a dry, cool and well ventilated place
and protect them from direct sunlight. Do not install them in a tightly closed
container. While charging the batteries may produce flammable gases, which may
be the cause of explosion if proper ventilation is not available. The best
temperature for battery storage and operation is between 15°C and 25°C. – Do
not place batteries near equipment generating sparks, or store them in dusty
areas. – Do not connect the battery to any plastic elements or housing
elements containing solvents. This may cause the battery body to unseal or
crack. – During storage of lead batteries they are self-discharged. The
storage time without charging is dependent on ambient temperature: from 6
months at 20 °C to 2 months at 40 °C. In order to prevent excessive battery
discharge, resulting in a significant reduction of their capacity and
durability it is required to recharge them in specified intervals. – Do not
discharge the battery to a voltage below that, specified by its manufacturer.
An attempt to recharge an over-discharged battery may cause a thermal hazard,
which results in battery deformation or in change of the structure and
distribution of the electrolyte in the battery as some of the water
evaporates. This worsens the battery parameters similar to prolonged
overcharging. Always recharge the battery immediately after discharging, even
if it was not discharged to the recommended cut off voltage. Leaving a
discharged battery for a couple of hours (sometimes even less than that if the
discharge was very deep) will cause sulphating. – Charging may only be
performed using a charger with specific parameters and under the conditions
set by their manufacturers. Failure to meet these conditions can lead to
leakage, overheating or even an explosion.

Cleaning and maintenance
ATTENTION! Use only the maintenance methods specified by the manufacturer in
this manual.
The casing of the meter may be cleaned with a soft, damp cloth using all-
purpose detergents. Do not use any solvents or cleaning agents which might
scratch the casing (powders, pastes, etc.).
Clean the probe with water and dry it. Before the probe is stored for a
prolonged period of time it is recommended to grease it with any machine
lubricant.
The reels and test leads should be cleaned with water and detergents, and then
dried. The electronic system of the meter does not require maintenance.
8 Storage
In the case of storage of the device, the following recommendations must be
observed: Disconnect all the test leads from the meter. Clean the meter and
all its accessories thoroughly. Wind the long test leads onto the reels. If
meter is to be stored for a prolonged period of time, the batteries must be
removed from the de-
vice. In order to prevent a total discharge of the accumulators in the case of
a prolonged storage,
charge them from time to time.
9 Dismantling and utilisation
Worn-out electric and electronic equipment should be gathered selectively,
i.e. it must not be placed with waste of another kind.
Worn-out electronic equipment should be sent to a collection point in
accordance with the law of waste electrical and electronic equipment.
Before the equipment is sent to a collection point, do not dismantle any
elements. Observe local regulations concerning disposal of packages, waste
batteries and accumulators.

13 Laboratory services
SONEL Testing and Calibration Laboratory has been accredited by the Polish
Center for Accreditation (PCA) certificate no. AP 173.
Laboratory offers calibration for the following instruments that are used for
measuring electrical and non-electrical parameters.
METERS FOR MEASUREMENTS OF ELECTRICAL PARAMETERS
o voltage meters, o current meters (including clamp meters), o resistance
meters, o insulation resistance meters, o earth resistance and resistivity
meters, o RCD meters, o short-circuit loop impedance meters, o power quality
analyzers, o portable appliance testers (PAT), o power meters, o multimeters,
o multifunction meters covering the functions of the above-mentioned
instruments,
ELECTRICAL STANDARDS
o calibrators, o resistance standards,
METERS FOR MEASUREMENTS OF NON-ELECTRICAL PARAMETERS
o pyrometers, o thermal imagers, o luxmeters.
The Calibration Certificate is a document that presents a relation between the
calibration standard of known accuracy and meter indications with associated
measurement uncertainties. The calibration standards are normally traceable to
the national standard held by the National Metrological Institute.
According to ILAC-G24 ,,Guidelines for determination of calibration intervals
of measuring instruments”, SONEL S.A. recommends periodical metrological
inspection of the instruments it manufactures no less frequently than once
every 12 months.
For new instruments provided with the Calibration Certificate or Validation
Certificate at the factory, recalibration should be performed within 12 months
from the date of purchase, however, no later than 24 months from the date of
purchase.
ATTENTION ! The person performing the measurements should be absolutely sure
about the efficiency of the device being used. Measurements made with an
inefficient meter can contribute to an incorrect
assessment of the effectiveness of health protection and even human life.
