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 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 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 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.
R
ISO
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 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.

3 Measurements
Notes:
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.
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.

Note:
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.
It is forbidden to disconnect test leads before the measurement is completed. Failure to
obey the above instruction will lead to high voltage electric shock and make it impossible to
discharge the tested object.
- Disabling t2 will also disable t3.
- Measuring time tn is independent of the t1, t2, t3 times set in MENU and overwrites them i.e. when tn
< t3 then the measurement time will be equal to tn.

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 R
ISO
- 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:
Page 27
MIC-10k1, MIC-5050 – USER MANUAL
23
when measuring insulation resistance between one of the cable conductors and the cable jack-
et, 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:
CU
I
DD
pr
min1
where:
I
1min
– current measured 1 minute after closing the circuit [nA],
Upr – test voltage [V],
C – capacitance [F].
Set the rotary switch of function selection at
DD. The meter is in the voltage measurement mode.

in a servicing point.
NOTE:
In MIC-10k1 up to SN: B40364 and MIC-5050 up to SN: B30117 gel batteries are used.
The charger is installed inside the meter and works only with the manufacturer’s rechargeable
battery pack. The charger is powered from the 230 V grid. It is also possible to power the unit from a
car lighter using an optional 12 V / 230 VAC converter.
ATTENTION!
Do not power the meter from sources other than those listed in this manual.
6.3 Charging rechargeable battery

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.
Page 59
MIC-10k1, MIC-5050 – USER MANUAL
55
- 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.
7 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.
Page 60

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.
