Insulation Resistance Meter
MIC-5001
index: WMGBMIC5001
Product features
• measurement voltage selected within the range of 50…500 V with steps of 50 V and from 500 to 5000 V
with steps of 100 V
• continuous reading of measured insulation resistance or leakage current
• automatic discharge of the measured object’s capacitance upon completion of insulation resistance measurement
• sound signalling of ve-second time intervals, facilitating capture of time characteristics
• timing of measurement time T1, T2 and T3 for measurement of dielectric absorption ratio (DAR) and polarization
index (PI)
• reading of actual measurement voltage during measurement
• protection against measurement of live objects
• two- or three-lead method of insulation resistance measurement
• insulation resistance measurement according to the RampTest method and breakdown voltage measurement
with ramping rate up to ~1 kV/s
• measurement of direct and alternating voltages within the range of 0...750 V
• 990-cell memory (11,880 entries), data transmission to PC via USB cable
• power supplied by accumulator

Application
Insulation resistance meter with adjustable testing voltage - up to 5 kV. It is
agreat tool for assessing the condition of electrical insulation in residential
buildings, industry, railways and other facilities of general use. Due to its param-
eters-excellent performance, low power consumption from batteries, theop-
tion of charging them during measurements, convenience of use anda high
ingress protection level - it is perfect for maintenance teams, testing motors, ca-
bles, street lighting or at the construction and maintenance of photovoltaic sys-
tems. The meter may be recommended to installers working on telecommuni-
cations and electric power systems that require the inspection of the insulation
sleeve/sheath resistance (UN ≤ 30 kV) to the voltage of 5 kV applied
for5 minutes.
Features
The meter may be used to measure the insulation resistance using the adjust-
able test voltage up to 5000 V. When testing the cables, it automatically dis-
charges their load at the moment of completing the measurement.
MIC-5001 allows the user to determine the insulation resistance by applying
linearly increasing voltage with the slope of 1 kV/s, according to standard
EEEStd 95TM-2002. This functionality is called RampTest.
In contrast the maximum test voltage, this slow and uniform method of apply-
ing test voltage protects the insulation against sudden “electrical stress”. This
process may reveal defects that cannot be observed in classic RISO resistance
measurement. If the tested insulation is weakened or defective, RampTest
will enable the user to determine its maximum withstand voltage. In addition,
this functionality is particularly useful in testing rotating machines or surge
arresters.
The meter has a built-in voltmeter of AC and DC voltages in the range
ofupto750 V. Extensive memory allows the device to record and send to a
computer nearly 12,000 measurement results. Download Sonel Reader soft-
ware from manufacturer’s website to analyse the measurement results and
present them in graphic form, e.g. current or resistance values shown in a func-
tion of time.
Capabilities
An important advantage of the device is its ability to a sufciently long opera-
tion after one recharging of batteries. Electricians performing tests on repeti-
tive objects or at short intervals do not have to worry about batteries discharg-
ing before completing the task. In addition, during the measurement work,
theuser may recharge device from an external power source, e.g. a powerbank
of 12 V/2 Ah.
