UNITEST TELARIS Loop Tester

Model: 8978


Key Functions
• Measurement of loop resistance and prospective
  short circuit current measurement without trippingthe RCD
• Line resistance and prospective short circuit current measurement
• Enables the user to measure each conductor
  resistance independently: PE resistance, phase resistance and neutral resistance
• Voltage and frequency measurement

General Information
• Integrated memory for approx. 250 measurement values
• Standard, built-in IR/RS-232 interface for transferring measurement data to the PC
• UNITEST software for recording test results is available as option
• Integrated socket test with contact electrode to enable the user to quickly establish incorrectly installed sockets and/or protective conductor failures
• Pre-selection of max. admissible contact voltage
• Clear and large LCD providing the user with an optimum visual indication of both test values and limits
• Auto power off

Special Features
• Patented measurement principle of loop resistance and prospective short circuit current measurement without tripping the RCD
