2.5. EMC
The instrument is designed and manufactured in accordance with the relevant standards for electromagnetic
compatibility, but it may still cause electromagnetic interference that interacts with other electronic equipment
nearby. Instrument and charger in operation may interfere with nearby sensitive electronic equipment and affect
their normal operation. Strong sources of electromagnetic radiation in the nearby environment may also interfere
with the instrument, causing unpredictable measurement errors, abnormal operation and, in particularly serious
cases, even irreversible damage.
• Avoid using instruments in environments of strong electromagnetic interference, such as near large
electrical utilities, high-power radio transmission facilities, wireless communication equipment, big
electric motors, etc.
• If abnormal display, abnormal jumping of measurement data and other abnormalities are detected
during operation, stop operation immediately and turn off the instrument. Continue operation only after
confirming that the surrounding electromagnetic compatible environment is suitable for continued
operation.
2.6. Mechanical injury
Instruments and tripods are heavy objects that may cause damage to people, equipment or other items if
dropped, fallen or broken. Be careful when handling, using, and transporting the instruments, as they are precision
instruments.
• To avoid the risk of injury from collapsing, the tripod should be set up carefully according to the
instruction, and the clamping screws should be tightened after the adjustment of the tripod legs.
• The instrument must be properly fixed on the tripod and checked frequently to avoid injury from falling
or damage to the equipment.
• In all cases, be aware of the possible danger posed by the sharp toe of the tripod legs. Care shall be
taken when setting or handling.
• Dropping and high intensity shaking of the transport case may damage the case and the instrument.
• Do not sit or stand on the transport case, and avoid placing heavy objects on the case.
• Do not use a transport case with broken body, damaged hinges, or latches.
