2. Safety Information

Please read all safety warnings and operating instructions carefully before using this product to prevent injury or damage to the device.

WARNING: LENGTH Port Usage

The LENGTH port is exclusively for cable length measurement. Connecting this interface to Power over Ethernet (PoE) or any other live/energized devices will directly damage the product and may pose a shock hazard.

General Safety Guidelines:

• Do not use the equipment if it appears damaged or abnormal. The internal protection may be compromised.
• Do not input over the specified range. Exceeding limits can cause injury to the user and damage the meter.
• Ensure test leads are properly connected and insulated before measuring voltages of 36V DC or above, and 25V AC or above.
• Remove test leads from the testing point before switching functions or ranges.
• The meter has full protections, but for safety, always select the correct function and range.
• Do not use the meter just before, during, or immediately after an electrical storm.
• Remove batteries if the meter will be stored for a long period to prevent leakage and damage.
• Do not use the meter to search or check energized cables. Contact with energized cables can cause harm to users and damage the meter.
• Only test leads should be connected to the meter when using the multimeter. Other ports connected to energized cables (except PoE equipment) can cause injury or damage.
• Check the battery if the low battery indicator on the LCD of the main body turns on, or if the red LED on the receiver flashes.
• Do not open the case. If repairs are needed, consult a professional.

6. Calibration

The ET618 allows for user calibration of both length and temperature to ensure accuracy.

6.1. Length Calibration

Due to variations in cable conductivity, measurement results may differ. The product can be calibrated as follows:

1. Connect a cable of known length (at least 5 meters) to the LENGTH jack on the Main Body.
2. In cable length measuring mode, press and hold the 'Analog/Digital Switch' and 'MODE' buttons together for 3 seconds to enter user calibrating mode. The measuring result will flash.
3. Use the 'Analog/Digital Switch' or 'MODE' buttons to adjust the displayed value to match the actual cable length.
4. Press and hold the 'Analog/Digital Switch' and 'MODE' buttons together to save the calibration result and exit calibrating mode. Pressing any other button will exit without saving.
5. To reset to factory settings, press and hold the 'Analog/Digital Switch' and 'MODE' buttons together after switching on the product.

6.2. Temperature Calibration

Temperature differences can affect measurement results. The ET618 has a temperature calibration mode:

1. After switching on the product, select the measuring mode. Press and hold the 'Analog/Digital Switch' and 'MODE' buttons together for 3 seconds to enter temperature calibrating mode. The measuring result will flash.
2. Use the 'Analog/Digital Switch' or 'MODE' buttons to adjust the displayed value to match a known temperature (e.g., from a mercury thermometer with 0.1°C resolution).
3. Press and hold the 'Analog/Digital Switch' and 'MODE' buttons together to save the calibration result and exit calibrating mode. Pressing any other button will exit without saving.
4. To reset to factory settings, press and hold the 'Analog/Digital Switch' and 'MODE' buttons together after switching on the product.
