Digital Earth Leakage Tester Model LT-02

Overview and features

  • The Earth Leakage Tester measures the insulation resistance between electrical blasting circuits and earth on a large liquid crystal display, which is easily read in both daylight and poor lighting underground.
  • It utilizes alternating current to prevent the false readings inherent in DC measuring instruments, due to polarization effects.
  • Certificates of approval: GME no. CT5.


  • The use of such an instrument is recommended for blasts involving a number of electric detonators.
  • SABS approved and safe for testing electric initiators at the work face. Permission to do so must be obtained from the DMR and all MHSA regulations must be adhered to.
  • The unit is powered by a replaceable PP3 9V Zinc Carbon battery and is capable of 80 hours of continuous use.

Notice and Maintenance

  • All service work to be performed by authorized AEC Electronics personnel only.
  • Approved for use in fiery mines.
  • Tester should only be opened to replace PP3 9V Zinc Carbon battery.
  • Exposure to temperatures above 60OC will cause permanent damage to the liquid crystal display
