Insulation resistance meter MIC-5010

The MIC-5010 is a portable, rugged, easy-to-use, 5 kV class insulation test meter.  The MIC-5010 has a wide measurement range, selectable test voltages, and excellent safety features.

Insulation resistance measurement features:

• User-selectable test voltage any from 50 to 1,000 V (with 10 V resolution) and 1,000 to 5,000 V (with 25 V resolution)
• Continuous indication of measured insulation resistance or leakage current
• Audio beeps every five-second periods to indicate measurement progress
• Indication of actual test voltage during measurement
• 1.2 mA and 3 mA test current
• Step voltage insulation resistance measurement (SV)
• Selectable test times (T1, T2 , T3 from 1 to 600 seconds) to measure one or two absorption coefficients
• Adjustable measuring time to 99′ 59’’
• Polarization index (PI) and dielectric absorption ratio (DAR) measurements
• Dielectric Discharge calculation (DD)
• High-noise immunity; digital filters function for measurements in high noise enviroment (10 s, 30 s , 60 s)
• Continuity measurement of protective connections and equipotential bonding in accordance with EN 61557-4
• Adjustable limits for measured resistance RISO and RCONT.
• Measurement of capacitance during the measurement of RISO
• DC and AC voltage measurement in the range of 0 to 600 V
• Meter conforms to EN 61557

Safety First Features.

• CAT-IV 600V, CAT-III 1000V
• Automatic discharge of tested object after the insulation resistance measurement completes to remove high-voltage charge remaining due to cable capacitance
• Protection against measuring live objects, measurement will not proceed
• Measurements with test leads up to 66 ft / 20 m length

Construction

• Backlit keyboard and display
• Rugged IP 54 case – Protected from water spray from any direction

Power Supply

• Power supply from battery packs, low battery warning indicator, built-in fast charger

Memory Features

• 990 cells of memory (11,880 records) to save test results
• Data transmission to a PC via USB cable

Insulation resistance measurement (two-lead)

Measurement range acc. to IEC 61557-2: 50k to 15.0 TΩ (IISOnom = 1.2 mA or 3 mA)

Values of measured resistance depending on measurement voltage

Measurement of leakage current

· ILmax – maximum current at short circuit of leads,
· resolution and units result from the measurement range of individual insulation resistance.

Step voltage insulation resistance measurement

· duration of each “step” adjustable from 30s to 5mins
· measurement result for each voltage step is stored in memory

Continuity measurement of protective connections and equipotential bonding with 200 mA current
Measurement range acc. to EN 61557-4: 0.12 to 999 Ω

· Voltage on open terminals: 4 to 24 V
· Output current at R < 2 Ω: Imin > 200 mA (ISC: 200 to 250 mA)
· Compensation of test lead resistance
· Current flowing in both directions, mean value of resistance is displayed

Capacity measurement

· Capacity measurement result is displayed after the RISO measurement

DC and AC voltage measurement

The acronym “m.v.” stands for a “measured reference value”.
