DISPLAY

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 RISO 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.

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 oper-ating 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.

Meter configuration

The setting sequence is as follows:

• Rated grid frequency (50 Hz and 60 Hz).

• Auto-off time (300 s, 600 s, 900 s) or none (—).

• Pin, the digit being set is blinking. Moving to the next digit with the F3 and F4 buttons.
  The same code must be entered in the computer programme for wireless transmis- sion. It is used to prevent access of unauthorized persons to the meter via wireless connections (external entities).

• Absorption coefficients for RISO: Ab1, Ab2 () or PI, DAR (). Each change sets the t1, t2 and t3 to their default values: for Ab1/Ab2 t1=15s, t2=60, t3=0, and for PI/DAR t1=30, t2=60, t3=0).

• Enabling (ON) and disabling (OFF) the limit settings.

• Software updates
  This topic is discussed in paragraph 6

Note:
To restore factory settings, press and hold the ON/OFF button for more than 5 seconds

Measurements

Notes:
The result of the latest measurement is remembered by the meter until a next measurement is started or the measuring function is changed by means of the rotary switch. It is displayed for 20 s. 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.

Measurement of insulation resistance
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 sur-face currents resulting in additional error in measurement results.

The converter output current ISC is limited at a level of 1.2 mA or 3 mA. Activation of current re-striction is indicated with a continuous audible signal. The measurement result is then correct, but the test voltage on the terminals is lower than the voltage selected before the test. Current limitation can happen in the first stage of a measurement due to the object’s capacitance becoming charged.
Actual measurement voltage as a function of the measured insulation resistance RX (for the maximum measurement voltage)

Double-lead measurement

Set the rotary function selection switch in one of the RISO positions, se- lecting at the same time the measure-ment voltage (positions 50 – 5000 V, selected with a step of 10 V in the range 50 V – 1 kV and with a step of 25 V between 1 kV and 5 kV). The meter is in the voltage measurement mode.

The setting sequence is as follows

times – in sequence t1 (1…600 s), t2 (1…600 s, but >t1) and t3 (1…600 s, but

t2) and t (independent of t1, t2 and t3: 1 s…99 min 59 s),

Short-circuit current ISC: 1,2 mA or 3 mA,

Limit.

For RISO the limit is the minimum value. The limit range is from 1 kΩ to 15 TΩ

The limit value is set using the and buttons. As the meter has many measurement sub-ranges, an algorithm for rapid increase or decrease of values is implemented. When holding the value key it changes very rapidly: first the hundreds, after 3 s tens, and after 3 s units etc. The limit setting is circular. The resolution of the set limit is related to the sub-range.
To deactivate the limit (displayed symbol —) press the button while in the 1 kΩ position or the button while in the 15 TΩ position.

During measurements controlled using the and buttons the display of the test voltage UISO for the IL leacage current may be changed.
The meter is equipped with an advanced digital filter for result stabilisation in difficult and unstable measurement conditions. When the F1 button is pressed before or during the measurement the meter will make calculations which will stabilise the fluctuations of the measurement results. The meter dis-plays a filtered value of measurements for a specified time period. The filter is selected by pressing the F1 button i.e. after the first press the result shall be displayed as a filtered value from the last 10 s, after the second press from the last 30 s, then for 60 s and finally the filter is turned off “- -“. The filter setting is circulating. The filter setting is erased automatically after the meter has been turned off or when the measurement function is changed using the rotary selector.
The ability to set the filter depends on the set t measurement time, for example when t=20 s it is only possible to set the filter for 10 s.

Note:
During measurements of insulation resistance, dangerous voltage up to 5 kV 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.
• Timer measuring the measurement time is started when UISO voltage is stabilized.
• Symbol informs of an operation with limited inverter power. If this condition persists for 20 seconds, the measurement is interrupted.
• A short tone informs of passing 5 s periods of time. When the timer reaches characteristic points (tx times), then for 1 s a symbol (mnemonic) of this point is displayed which is accompanied by a long beep.
• If any of the measured values of partial resistance is out of range, the value of the absorption coefficient is not displayed – the display shows dashes.
• During the measurement a yellow LED is lit.
• After completion of measurement, the capacitance of the object tested is discharged by shorting RISO+ and RISO- terminals with resistance of 100 k.
• Capacitance measurement is carried out only while the capacitance of the tested object is being discharged. If the RISO measurement is interrupted before the RISO value stabilizes, the discharge will start too early, so the capacitance measurement result may not be correct.
• In case of power cables measure the insulation resistance between each conductor and other conductors shorted and grounded (figure below).

Three-lead measurement
In order to eliminate the influence of surface resistance in transformers, cables, etc. the three-lead 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:
• when measuring insulation resistance between one of the cable conductors and the cable shield, the effect of surface resistances (important in difficult weather conditions) is eliminated by con-necting 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

Measurements with increasing voltage – SV
In this mode the meter performs a series of 5 measurements with increasing voltage; the voltage change depend on the set maximum voltage:

• 1 kV: 200 V, 400 V, 600 V, 800 V, 1000 V,
• 2.5 kV: 500 V, 1 kV, 1.5 kV, 2 kV, 2.5 kV,
• 5 kV: 1 kV, 2 kV, 3 kV, 4 kV, 5 kV.

The end result for each of the 5 measurements is saved which is signalled by a beep and an appropriate icon.

The setting sequence is as follows:

• maximum (final) measurement voltage: 1 kV, 2.5 kV and 5 kV,
• duration of individual measurements in the range between 30 s…5 min,
• short-circuit current ISC: 1.2 mA or 3 mA

Note:
Further information, starting the measurement, displayed symbols, result readout and component view operate identically as the RISO measurement.

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:

where:

• I1min – current measured 1 minute after closing the circuit [nA],
• Upr – test voltage [V],
• C – capacitance [UF].

The measurement result testifies to the insulation condition, you may compare it with the table below:

The setting sequence is as follows:

• charge time: 1 min…60 min,
• charge voltage: 100 V, 250 V, 500 V 1 kV, 2.5 kV, 5 kV,
• maximum charge current: 1,2 mA or 3 mA.

Note:
In an environment with strong interferences the measurement may be affected by additional uncer-tainty.

Low-voltage measurement of resistance
Measurement of resistance of protective conductors and equipotential bonding with ±200 mA current

For RCONT the limit is the minimum value. The setting limit reflects the function: from 0.01 Ω to 999 Ω. The value of the limit set in the same way as for RISO.
To deactivate the limit (displayed symbol —) press the button while in the 1 kΩ position or the button while in the 999 Ω position

Calibration of test leads
In order to eliminate the impact of the resistance of test leads on measurement result, the compensation (autozeroing) of resistance may be performed.

Tightness test of MV cable jacket

Tightness test of MV cable jacket consists of applying a test voltage between its metal sheath or its return conductor and the ground. During the measurement, pay attention to the value of IL current.
The test voltage and the measurement time depend on the type of the tested object and test guidelines. For example, for a cable with polyethylene insulation:

• test voltage according to standard HD 620 S1: ≤5 kV,
• measurement time after voltage stabilization: 1-10 min,
• positive result according to HD 620 S1: when no ground fault has occurred.

Memory of measurement results

The MIC-5010 and MIC-5005 meters are equipped with a memory capable of storing 11880 single test results (990 cells, each may contain a set of measurements of: R ISO and RCONT). The whole memory is divided into 10 memory banks each of them containing 99 memory cells. Thanks to dynamic memory allocation, each of the memory cells can contain different quantity of single measurement results, de-pending 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 measure-ment points and the memory bank numbers to individual facilities. The user may also perform measure-ments 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:

• A single cell may contain either a RISO 2(3)p measurement result, a RISO SV, or DD. – After entering the measurement result, the ID number of the cell is automatically increased.
• It is recommended to delete the memory after reading the data or before performing a new series of measurements that may be stored into the same memory cells as the previous ones.

Storing the measurement results in the memory

Note:
Complete set of results (main result and supplementary results) for a given measuring function and preset measurement settings are stored in the memory.

Viewing memory data

Note:
While viewing RISO results, the field of timer / memory displays alternately bank and cell numbers and the time in which the result was entered into memory. This applies to all RISO measurements.

Deleting memory data
You can delete the entire memory or its individual banks.

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 situa-tion adequately. Too low temperature should prevent starting the process of charging, which might ir-reparably 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. “Swol-len” 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 dam-age 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 per-sons and children.
• When you notice any changes in the Lithium-Ion battery pack (e.g. changes in colour, swelling, exces-sive temperature), stop using the battery pack. Li-Ion batteries that are mechanically damaged, over-charged 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.

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 depend-ent 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 evap-orates. 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 man- ual.

• 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.

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 device.
• In order to prevent a total discharge of the accumulators in the case of a prolonged storage, charge them from time to time.

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.

• Note : For insulation resistance below RISOmin there is no accuracy specified because the meter works with the adjustable current limit in accordance with the following formula:

• where:

  • RISOmin – minimum insulation resistance measured without limiting the converter current
  • UISOnom – nominal test voltage
  • IISOnom – nominal converter current (1.2 mA or 3 mA)

• Additional error in the three-lead measurement (impact of G terminal): 0.05% with reduced current leakage incurred by 250 kΩ resistance during 100 MΩ measurement with 50 V measurement voltage.

• Max. short-circuit current ISC: 3.6 mA ±15%.

• ISC current in the remaining load range shall be selected from the following values: 1.2 mA, 3 mA.
