  • Page 6: Checking A Rcd Test

    4. Check RCD tester A. CHECKING A RCD TESTER RCD tester simulates a current between live and earth to trip TEST BOX. The disconnect time of relay is shown on RCD tester usually in milli-seconds if TEST BOX and RCD tester select the correct current and the correct time range.
  • Page 7 BESANTEK B. CHECKING RCD TEST TIME & CURRENT Plug the TEST BOX into an unprotected supply (no RCD trip) and plug the RCD tester into the left- h and socket marked 'RCD TESTER' on the TEST BOX is shown as below.

  • Page 8: Checking An Installation Or Insulation Tester

    BESANTEK Select the 150mA or 30mA with "x5I" button (fif available). Set the TEST BOX to 150mN30mS and press the "test" button. Record the time displayed on the tester. Allow from 27mS to 33mS, ± 1mS. Tripped is approximate to 45mA tolerance (150mA± 45mA) Over current is over 195mA.

  • Page 9: Checking The Reading Accuracy

    Select the lowest test voltage (100V or 250V) range on the tester. Press the “test” button on the tester. Note the voltage LED (100V or 250V) on the TEST BOX. It should be lit with the same range on the tester. Record the reading on the tester. Repeat the same step on the other test voltage ranges.

  • Page 10: Checking The Continuity Measurement

    BESANTEK C. CHECKING THE CONTINUITY MEASUREMENT The continuity or low resistance measures the resistance in TEST BOX has three low value resistors for p recision measurement. Many testers have a null function to zero out this leads resistance exactly before making measurement. The instruction shall show how to use this function.

  • Page 11: Checking For The Ac Voltage Measurement Function

    Select the fitting range on the tester in order to read precise measurement from each range on the tester. For example, if the tester has a 200Ω, 20Ω and 2Ω ranges. Use the 200Ω range to measure “10Ω”, the 20Ω to measure “2Ω” and the 2Ω...

  • Page 13: Checking A Loop Tester

    BESANTEK 6. Checking a LOOP tester Loop tester is an instrument of measuring the resistance of the main supply. Its measurement is made in Ohm. Plug the TEST BOX into an unprotected supply (no RCD trip) and plug the loop tester into the central socket marked 'WIRING CHECK' on the TEST BOX is shown as below.

  • Page 14: Limited Warranty

    Common Problems Solution Supply trips out when test TEST BOX must plug into button pressed unprotected supply. A: Faulty loop tester main supply. No power to Loop Tester B: TEST BOX does not plugged into AC supply. Noise on main supply. Try a No reading on tester different main Socket for the TEST BOX.
