MIC-5010 ● MIC-5005 –USER MANUAL

Thank you for purchasing the MIC-5010 / 5005 insulation meter. Please acquaint yourself with this

manual to ensure safe operation, and avoid operational errors that can affect measurement results.

This device complies with part 15 of the FCC Rules. Operation is subject to the following two

conditions: (1) This device may not cause harmful interference, and (2) this device must accept

any interference received, including interference that may cause undesired operation.

This equipment has been tested and found to comply with the limits for a Class A digital device,

pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection

against harmful interference when the equipment is operated in a commercial environment. This

equipment generates, uses, and can radiate radio frequencyenergy and, if notinstalled and used

in accordance with the instruction manual, may cause harmful interference to radio communi-

cations. Operation of this equipment in a residential area is likely to cause harmful interference

in which case the user will be required to correct the interference at his own expense.

CAUTION:

Equipment changes or modifications not expresslyapproved by SONEL S.A., the partyrespon-

sible for FCC compliance, could void the user’s authority to operate the equipment, and could

create a hazardous condition.

1 Safety

The MIC-5010 / 5005 insulation meter is designed to test the safety of electrical installations, for

protection against electric shock and fires. For correct operation and accuracy of obtained results ob-

serve the following recommendations:

Before operation of the meter acquaint yourself thoroughly with this manual and pay close attention

to the safety regulations and instructions provided by Sonel.

Any application that differsfrom those described in this manual may result in a damage to the device

and constitute a source of danger to the user.

The meter must be operated only by qualified personnel authorised to perform work on electrical

systems. Operating the meter by unauthorised personnel may result in damage to the device and

constitute a source of danger to the user.

During measurements of insulation resistance dangerous voltages up to 5 kV occur at the ends of

the test leads of the meter.

Before measurement of insulation resistance ensure that the tested object is not live, and discon-

nected from the mains power supply.

Do not disconnect test leads from the tested object before the measurement is completed (see par.

3.1.1.) otherwise the electrical charge on the object will not be discharged leaving a high voltage

present on the object under test, creating a serious risk of electric shock.

Compliance with occupational health and safety regulations and relevant fire regulations must be

adhered to. Before starting work in special environments, e.g. potential of fire-risk or explosive en-

vironments, consult with the person responsible for health and safety.

Do not operate the meter:

Which is damaged, completely or partially malfunctioning

With incorrect, or damaged test leads with damaged insulation

When stored for an excessive period of time in adverse conditions (e.g. excessive humidity). If

the meter is transferred from a cool to a warm environment with a high relative humidity do not

use it for 30 minutes until the meter has warmed up to the new ambient temperature.

The message indicates insufficient voltage of the internal power supply. The battery must be

recharged.

The error message ErrX, where Xis a number between 0 to 9, indicates incorrect operation or

malfunction of the meter. If after restarting the device this situation continues, the meter needs ser-

vicing by Sonel or an authorized Sonel service center.

Before starting measurements choose the correct measurement function and make sure that test

leads are connected securely to the measuring terminals.

Do not power the meter from sources other than those described in this manual.

The RISO measurement terminals of the meter are protected electronically from overload, or from

connection to a live circuit up to 660V rms for 60 seconds.

Repairs must be performed by Sonel or an authorised Sonel service center.

Note:

Due to continuous development the actual appearance of the display may slightly differ from

the information presented in this operating manual.

ATTENTION!

To display the correct battery discharge status first completely discharge and then fully re-

charge the battery.

Note:

Installing drivers in 64-bit Windows 8 and Windows 10 may result in displaying an "Installa-

tion failed" message. Windows 8 and Windows 10 by default block drivers without a digital

signature. Disable the driver signature enforcement in Windows.

2 Meter configuration

Turn on the meter holding the MENU

button pressed.

The and buttons are used to set pa-

rameter values. The and buttons move

to the next parameter.

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 (---).

MIC-5010 ● MIC-5005 –USER MANUAL

Pin: Select or hange the flashing digit. Moving to the next digit

with the F3 and F4 buttons and set the desired pin #.

The corresponding PIN code is required for wireless transmission to computersoft-

ware, and to prevent unauthorized access to the meter.

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 ( ) and disabling ( ) the limit settings.

Software updates.

This topic is discussed in section 6.

Enabling ( ) and disabling ( ) the buzzer.

Test voltage accuracy: Hi –0…5%, Lo –0…10%

Press ENTER to confirm and go to the meas-

urement screen.

Press ESC to go to the measurement screen

without approving the changes.

Note:

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

3 Measurements

Notes:

The last measurement is retained by the meter until a new measurement is started or the measuring

function is changed by the rotary switch. The measurement result displays for 20 s. It may be recalled

by pressing ENTER, also after the meter is turned off and then on again.

WARNING:

Do not change the range switch during a measurement to prevent damage the meter and

threaten user safety.

3.1 Measurement of insulation resistance

WARNING:

De-energize the object under test. The tested object must not be live.

Note:

During measurement make sure the test leads do not touch each other, or that the probes or

crocodile clips come into contact with each other, otherwise surface currents will result in

additional errors.

The meter output current is limited at of 1.2 mA or 3 mA. Current limiting is indicated with a con-

tinuous audio tone. Measurement results are correct, but the test voltage on the terminals will be lower

than the selected voltage of test. Current limit occurs 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
