5.2 Connecting to Mains
Connect the provided power cord to the mains input socket on the top of the tester and then to a suitable electrical outlet. Ensure the outlet provides 230V (Ph/N) – 10/+6% 50/60 Hz.
6. Operating Instructions
The Metravi 1813 is designed to test the trip values of Residual Differential Devices (RDDS), including ELCBs and RCDs, in terms of trip time (ms) or trip current (mA).
6.1 Basic RCD/ELCB/RDDS Testing Procedure
- Power On: Turn the rotary switch from OFF to the desired test function (e.g., x1, x1/2, Auto).
- Connect to Circuit: Plug the tester's power cord into the circuit you intend to test. Ensure the circuit is live and within the specified voltage range.
- Select Test Current Multiplier: Use the rotary switch to select the desired trip current multiplier (e.g., x1/2, x1, x2, x5). The 'Auto' setting can automatically determine the trip current.
- Select RDD Type: Press the N/S button to select between Normal (N) or S (delayed) type RDD test, as appropriate for the device being tested.
- Select Phase Angle: Press the 0°/180° button to select the desired phase angle for the test.
- Initiate Test: Press the TEST button. The tester will inject a fault current and measure the trip time or trip current.
- Read Results: The 3-digit LCD display will show the measured trip time (in ms) or trip current (in mA).
- Interpret Results: Compare the displayed values with the specifications of the RCD/ELCB/RDDS being tested to ensure it operates within acceptable limits.
The Metravi 1813 supports testing of 10mA, 30mA, 100mA, 300mA, 500mA, and 1000mA differential circuit breakers, regardless of whether they are normal or delayed types.
6.2 Voltage Measurement
To measure voltage:
- Turn the rotary switch to the V position.
- Connect the tester to the circuit.
- The display will show the measured voltage.

9. Troubleshooting
If you encounter issues with your Metravi 1813 tester, refer to the following common problems and solutions:
- Device does not power on:
- Check if batteries are correctly installed and have sufficient charge. Replace if necessary.
- Ensure the rotary switch is not in the OFF position.
- No reading or incorrect reading during test:
- Verify that the tester is properly connected to a live circuit.
- Ensure the circuit voltage is within the operating range (230V).
- Check if the correct test function (current multiplier, RDD type, phase angle) is selected.
- The RCD/ELCB/RDDS might be faulty or tripped. Reset the breaker and retest.
- Warning signals activated:
- If a 400V network voltage warning appears, disconnect immediately. The circuit voltage is too high for safe operation.
- If a contact potential >50V warning appears, exercise extreme caution. There is a significant voltage difference.
If problems persist, contact customer support for assistance.
