1 Safety
MIC-5001 meter is designed for performing check tests of protection against electric shock in
mains systems. The meter is 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-5001 meters must be operated only by appropriately qualified personnel with relevant certifi-
cates authorising the personnel to perform works on electric systems. Unauthorized use of the me-
ter may result in its damage and may be a source of serious hazard to the user.
During measurements of insulation resistance, dangerous voltage of approx. 5kV occurs at the
ends of measurement wires 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. 4.1); 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 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 device when:
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.
Message ErrX displayed in the main field , where X is a number from 0 to 9, indicate incorrect op-
eration of the meter. If after restarting the device this situation is repeated - it indicates that the
meter is damaged. Please contact the manufacturer's service.
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 750V rms for 60 seconds.
Repairs may be performed only by an authorised service point.
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.

5 Memory of measurement results
MIC-5001 meters have memory divided into 10 banks of 99 cells. Thanks to dynamic memory allocation, each of the memory cells can contain different quantity of single measurement results, depending on the needs. Optimal use of the memory can be ensured in this way. Each measurement result can be stored in a memory cell marked with a selected number and in a selected memory bank.
Thanks to this, the user of the meter can, at his/her option, assign memory cell numbers to individual
measurement points and the memory bank numbers to individual facilities. The user may also perform
measurements in any chosen sequence and repeat them without losing other data.
Memory of measurement results is not deleted when the meter is switched off. Thanks to this, the
data can be later read or sent to a computer. The number of a current memory cell or memory bank is
not changed either.
Note:
- Results of measurements performed for all measuring functions can be stored in one memory cell,
excluding U .
- After entering the measurement result, the ID number of the cell is automatically increased.

9.3 General principles regarding using Ni-MH rechargeable batteries
- Store the he rechargeable batteries (the meter) in a dry, cool and well ventilated place and protect
them from direct sunlight. The temperature of the environment in the case of prolonged storage should
not exceed 30°C. If the rechargeable batteries are stored for a long time in a high temperature, then
the occurring chemical processes may reduce their lifetime.
- Rechargeable batteries NiMH usually lasts for 500-1000 charging cycles. The rechargeable batteries
reach their maximum capacity after being formatted (2-3 charge and discharge cycles). The most important factor which influences the lifetime of rechargeable batteries is the level of their discharge. The
deeper the discharge level of the batteries, the shorter their lifetime.
- The memory effect is limited in the case of NiMH batteries. These batteries may be charged at any
point with no serious consequences. However, it is recommended to discharge them completely every
few cycles.
- During storage of Ni-MH rechargeable batteries they are discharged at the rate of approximately 20%
per month. Keeping rechargeable batteries at high temperatures may accelerate this process even
100%. In order to prevent excessive discharge of rechargeable batteries, after which it would be necessary to format them, it is recommended to charge them from time to time (even if they are not used).
- Modern fast chargers detect both too low and too high a temperature of the battery pack and react to
the situation adequately. Too low temperature should prevent starting the process of charging, which
might irreparably damage rechargeable batteries. An increase of the temperature of the rechargeable
batteries is a signal to stop charging and is a typical phenomenon. However charging at a high ambient temperature apart from reducing batteries' lifetime causes an accelerated increase of their temperature and the result is that the batteries are not charged to their full capacity.
- Please note that when the batteries are charged with a fast-charger they are charged only to approx.
80% of their capacity - better results can be achieved by continuing charging: the charger enters trickle-charging mode and during the next few hours batteries are charged to their full capacity.
- Do not charge or use the batteries in extreme temperatures. Extreme temperatures reduce the lifetime of batteries and rechargeable batteries . Avoid placing devices powered by rechargeable batteries in very hot environments. The nominal working temperature must be absolutely observed.

16 Laboratory services
Research and Calibration Laboratory of SONEL SA offers calibration of the following in-
struments used for electrical/non-electrical measurements:
- meters for electrical protective measurements: insulation resistance, impedance and resistance of short-circuit loops, earthing resistances and earth resistivity, RCD parameters
and multi-functional meters that perform the above functions,
- electrical safety meters,
- multimeters,
- power quality analysers,
- meters for measuring low resistance values,
- infra-red cameras,
- pyrometers,
- luxmeters.
In addition, the Laboratory performs voltage, current and resistance calibration.
A calibration certificate is a document confirming compliance of parameters declared by the
manufacturer of tested device with national standards, specifying the measurement uncertainty.
Pursuant to standard EN ISO 10012:2003 "Measurement management systems — Require-
ments for measurement processes and measuring equipment", SONEL S.A. recommends for
its instruments to be periodically tested, observing the interval of 13 months.
For new devices with calibration certificates, the next metrological inspection (calibration) is
recommended within 13 months from the date of purchase, but not later than 19 months from
the date of manufacture.
Note:
In case of instruments used for tests related to the protection against electric shock,
the person performing measurements should have complete confidence in the effi
ciency of operated apparatus. Measurements carried out with malfunctioning meter
may cause wrong assessment of tested equipment in terms of its protection features
