Megger S1-552 5kV Insulation Tester Megohmmeter - NIST Calibrated with Warranty
- The S1-552 is a microprocessor controlled 5 kV insulation tester offering measurement capability of up to 15 TΩ. The instrument performs automatic tests and has data storage and data retrieval facilities. Polarization index and dielectric discharge tests are performed automatically, and test duration and voltages can be adjusted according to user preference for these tests. A step voltage test can be performed automatically, with a default voltage of 1 kV, and test duration of 5 minutes. It is possible for the user to set different voltages and test durations for the step voltage test.The S1-552 can be powered from the mains supply or by its own internal rechargeable battery, which provides for at least 6 hours of continuous testing with a 100 MΩ load. A battery level indicator on the LCD display indicates battery capacity. Connecting power to the mains supply connector will automatically charge the battery whether the instrument is switched ‘on’ or ‘off’, except during testing. A high level of internal isolation allows the instrument to be used while the unit is supplied from the mains.An internal battery management system switches the instrument off after ten minutes of inactivity. If the battery approaches a very low state of charge the instrument turns itself off, and mains power must be applied before the instrument can be used again. Recorded test results and settings will not be lost when the instrument is switched off.
