Technical specifications of Megaohmmeter Е6-40

  • Simulate insulation test voltages (DC) 100, 250, 500, 1000 и 2500 V with 10% of tolerance.
  • Factional accuracy of resistance measuring represents in a table 1 below

Table 1 – Factional accuracy of insulation resistance measuring

1) Rx- measured value of resistance, MOhm
2) It is necessary to use shielded-type cable to get this Measuring uncertainty

  • Measurement range depending on test voltages in a table 2 below

Table 2 - Measurement range

  • Setting time at most 30 sec. if maximum of measuring object’s electric capacitance is not more than 1
  • E6-40 make measurement of dielectric absorption and polarizability Ratio
  • E6-40 keep in memory 20 last measurements
  • Device can perform measurements of 50 Hz AC external voltage with rms value from 50 to 600V. Measuring uncertainty of external voltage is not above 10%.
