MIC-2501 Insulation resistance meter

The meter may be used to measure the insulation resistance using the testvoltage up to 2500 V. When testing the cables, it automatically discharges their load at the moment of completing the measurement. MIC-2501 allows user to measure the continuity of protective conductors and equipotential bondings with current exceeding 200 mA in both directions. 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.

Manufacturer: SONEL S.A. (Польша).
Features
  • Measurement voltage within the range of 100…2500 V, selected in steps of 100 V
  • Ccontinuous 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 five-second time intervals, facilitating capture of time characteristics
  • Timed measurement times T1 , T2 and T3 for measurement of absorption coefficients (Ab/PI/DAR) at 15, 60 and 600 s and polarization index
  • Reading of actual measurement voltage during measurement
  • Protection against measurement of live objects
