1 Safety

MIC-2510 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 the correctness
of the 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 determined 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-2510 meters must be operated only by appropriately qualified personnel with relevant certifi-

cates authorising the personnel to perform works on electric systems. Operating the meter by un-

authorised 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 2.5 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); 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 the following:

 a damaged meter which is completely or partially out of order,

 a meter with damaged test leads 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).

 Displayed BATT symbol indicates insufficient voltage of power supply and the need to charge the

accumulator or replace batteries.
 Symbols ErrX, where X is a number 1…9, indicate incorrect operation of the meter. If after restarting

the device this situation is repeated - it indicates that the meter is damaged.
 If after switching ON and displaying software version, message is displayed and the meter

switches OFF - send the meter for servicing. When is displayed every time after the meter is

switched ON, but the meter enters the measurement mode – update its software.
 Before measurement, choose a correct measurement function and make sure that test leads are

connected to respective measuring terminals.
 Do not operate a meter with an open or incorrectly closed battery (accumulator) compartment or

power it from other sources than those specified in the present manual.

 R

ISO

inputs are electronically protected against overloads (caused by e.g. connecting the meter to a

live circuit) up to 600 V for 60 sec.
 Repairs may be carried out 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.

During the measurement, AC voltage appeared or the object
cannot be discharged for 30 seconds. After 5 seconds the
meter returns to its default state - voltmeter.

3.1.2 Three-lead measurement

In order to eliminate the influence of surface resistance in transformers, cables, etc. a three-lead
measurement is used. For example:
 at the measurement of inter-winding resistance of a transformer, G socket of the meter should be

connected to the transformer tank;

OPERATING MANUAL MIC-2510 version 1.11

13

 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 con-

necting a piece of metal foil wounded around the insulation of 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.

3.1.3 Measurement with AutoISO-2500 adapter

Set the rotary switch of function selection at
one of R

ISO

position, choosing measurement
voltage (on position 50...2500V selected
with 10V step). The meter is in the voltage

Press START button to initiate the measurement (no need to hold it,
the measurement is done automatically). First, checking of voltages
on particular pairs of conductors is performed. If any of the voltages
exceeds the permissible value, then it is displayed on the display, LED
lights red and the measurement is cancelled (exceeding U

L1-N

voltage
prevents commencing the measurement).
The measurement is performed continuously until the meter reaches
the preset time for the last pair of conductors.

Symbol (mne­monic) of cur­rently measured
pair of conduc­tors

View of the screen during
measurement.

Note:

- The meter detects AutoISO connection for approx. 1 sec.

- After connecting AutoISO, a default voltage measurement is performed on a pair of conductors L1-N,
for all types of conductors

- For power cables PE means earthing cable.

- In case of measurements on power cables the adapter shorts the remaining wires to E line, e.g. 5-P
measurement for a power cable and indication of L1-PE pairs, means that the adapter connects line L1
to one of the meter's ISO inputs, while the contained lines L2, L3, N, PE, E are connected to the second
ISO input.

Due to the fact that AutoISO-2500 adapter shorts a few input lines during meas­urements on power cables, it is essential to ensure that the tested cable is dis­connected from external power sources. The meter checks for the presence of
voltage before measurement, but it does not prevent connection of voltage dur­ing the measurement. When voltage is applied in this situation, it will cause a
short circuit and will damage AutoISO-2500 module.

- Other messages, displayed symbols, results and scrolling through result components as in case of
double-lead measurement, additionally - switching between results of individual pairs with SEL button.

- In cases of errors , LIMIT ! the measurement is interrupted only for the current pair of conductors.
Error tops the measurement.

Additional information displayed by the meter

During measurement the meter has detected the error re­lated to AutoISO (e.g. disconnection).

4 Memory of measurement results

MIC-2510 meters are equipped with a memory capable of storing 11880 single test results (990

cells, each of which may contain a set of measurements of R

ISO

with AutoISO, R

CONT

and temperature).
The whole memory is divided into 10 memory banks with 99 cells in each bank. 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 can also
perform measurements in any 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 RX and U .

- After entering the measurement result, the 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.

7.4 General principles regarding using NiMH rechargeable batteries

- If you do not use the device for a prolonged period of time, then it is recommended to remove the
rechargeable batteries and store them separately.

- Store the rechargeable batteries 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.

- NiMH batteries withstand normally 500-1000 charging cycles. These batteries reach their maximum
capacity after being formatted (2-3 charge/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 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 NiMH batteries they are self-discharged at the rate of approximately 30% 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 rechargeable batteries 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 trickle­charging mode and during the next few hours batteries are charged to their full capacity.

- Do not charge or use rechargeable 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.

8 Cleaning and maintenance

NOTE!

Apply solely 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.).

The electronic system of the meter does not require maintenance.

9 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.
 In the case the meter is to be stored for a prolonged period of time, batteries/rechargeable batteries

must be removed from the device.

 In order to prevent a total discharge of the rechargeable batteries in the case of a prolonged storage,

charge them from time to time.

10 Dismantling and Disposal

Used electrical and electronic equipment should be collected selectively, i.e. it must not be placed
with another kinds of waste.

Used electronic equipment should be sent to a collection point in accordance with the Used Electri-

cal and Electronic Equipment Act.

Before the equipment is sent to a collection point, do not dismantle any elements.
Observe the local regulations concerning disposal of packages and used batteries/rechargeable

batteries.
