The PCE-IT 55 Megohmmeter determines insulation resistance up to a maximum of 2000 MΩ (for auxiliary voltages of 250, 500 and 1000V). This Megohmmeter also offers the ability to measure alternate and continuous currents up to a maximum 750V / 1000V and resistance up to 2 kΩ. Includes test current and a warning whistle. Readings can be stored by pressing a single key. The device meets with these standards: DIN 57 411 part 1 / VDE 0411 part 1, protective measures for electronic devices (IEC1010-1) and DIN VDE 0413 (Megohmmeter). It comes calibrated from the manufacturer and an optional laboratory calibration and ISO certificate can be ordered separately for annual recalibrations.
