ET Instrumente EST-SL - PE tester

Good electrical connection of PE conductor with the instrument casing ensures, that no voltage can occur on the case because of internal electrical fault or blown fuse. Testing of the PE conductor resistance is a very important part of every safety test. With adjustable AC current between 5 A AC and 30 A AC, resistance change is measured with a four-wire measurement setup. The standard measurement range is  0 - 0.2 Ohm. Unit comes as standard with USB interface and optionally, you can choose analogue, RS232 and/or Ethernet interfaces.
