2. **Test Leads Connection:** Connect the test leads to the RCD tester securely. Proper connection is essential for the device to accurately measure the RCDs.
3. **Power On:** Turn on the CZ20053 RCD Tester. Check if the device powers up and displays the necessary indicators on the screen.
4. **Current Multiplier Selection:** Select the appropriate current multiplier (x1/2, x1, x5) based on the specific RCD being tested. Choosing the correct multiplier ensures accurate testing results.
5. **Test Button Press:** Press the test button to initiate the testing process. Verify that the device responds appropriately to the test command.
6. **Result Display:** Check the full icon display for the test results. The display should provide clear and accurate information regarding the RCD being tested.
7. **Tripping Check:** If the RCD being tested trips during the test, verify that the trip time ranges (40 - 3000ms) align with the expected values based on the current/multiplier settings.
8. **Non-Tripping Check:** If the RCD does not trip during testing, confirm that the device indicates the correct functionality of the RCD.
By following these steps and observing the device's response during testing, you can ensure that your AEGIS CZ20053 RCD Tester is functioning correctly and providing accurate results for testing Residual Current Devices.
