The manual recommends using cables with a diameter of 5mm to 6mm to ensure IP54 protection.
The transmitter should be powered on and preheated for 15 minutes to ensure stable and accurate operation.
Only neutral reagents should be used; corrosive solvents like acids, alkalis, or household detergents must be avoided.
This may be caused by the transmitter shell ground not being grounded, strong RF interference at the site, or unshielded cables.
