    253V, 50Hz. ● For safety reasons, only use the Test Leads designed to be used with this Tester and recommended by KEWTECH. ● Use only grounded mains outlets to supply the Tester. ● Do not touch the device under test whilst testing is in progress.
  • Page 4 DANGER ● Since a high voltage of 500V is being output continuously, when measuring insulation resistance, the user may get an electrical shock. Any capacitors in the appliance under test may become charged during testing and may contain hazardous voltages do not touch them. ●...
  • Page 5 Measurement Category To ensure safe operation of measuring instruments, IEC 61010 establishes safety standards for various electrical environments, categorized as O to CAT IV, and called measurement categories. Higher-numbered categories correspond to electrical environments with greater momentary energy, so a measuring instrument designed for CAT III environments can endure greater momentary energy than one designed for CAT II.
