Page 3: Safe Testing
1. This instrument must only be used by a competent and trained person and operated in strict accordance with the instructions. KYORITSU will not accept liability for any damage or injury caused by misuse or non-compliance with the instructions or with the safety procedures. - Page 4 Failure to follow the instructions may cause injury, instrument damage and/or damage to equipment under test. Kyoritsu is by no means liable for any damage resulting from the instrument in contradiction to this cautionary note. ● Never open the instrument case - there are dangerous voltages present.
- Page 5 ● For safety reasons only use accessories (test leads, probes, cases, etc) designed to be used with this instrument and recommended by KYORITSU. The use of other accessories is prohibited as they are unlikely to have the correct safety features.
- Page 6 ○ Measurement categories(Over-voltage categories) 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.

Page 13: Residual Current Device (Rcd) Test
5. Residual Current Device (RCD) Test 5.1 RCD test RCD is a switching device designed for breaking currents (opening the contacts) when the residual current attains a specific given value. It works on basis of current difference between phase currents flowing to different loads and returning current flowing through neutral conductor (for a single phase installation). - Page 14 This tripping time values are concerning the RCD's correctly mounted following the manufacturer's specifications. The RCD tester Model 5406A continues driving test current until RCD trips or up to max test time. This test is named Trip test (×1 I⊿n) or Fast trip test (×5I⊿n).
- Page 15 In order to check the leakage or fault currents there are specific leakage clamp meters as Model 2432, Model 2433, Model 2413F. The RCD tester Model 5406A can test the Trip out time t⊿ and the Tripping current I⊿. ̶ 13 ̶...

The fact that the RCD has not tripped will be evident because the P-N and P-E LEDs will still be on.

7. SERVICING If this tester should fail to operate correctly, return it to your distributor stating the exact nature of the fault. Please remember to give all the information possible concerning the nature of the fault, as this will mean that the instrument will be serviced and returned to you more quickly. -
Page 23: Case And Strap Belt Assembly
8. CASE AND STRAP BELT ASSEMBLY Correct assembly is shown in Fig 11. By hanging the instrument round the neck, both hands will be left free for testing. Pass the strap belt down through the side panel of the main body from the top, and up through the slots of the probe case from the bottom. - Page 24 DISTRIBUTOR 92-1490B 10-16 Kyoritsu reserves the rights to change specifications or designs described in this manual without notice and without obligations.
