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%.
  • Existence of external voltage is monitoring permanently and independently from selected measuring mode. In the presence of external voltage on measuring terminals, voltage value is flashing on display. If the presence external voltage on measuring terminals more than 40V resistance measuring is not possible.
