Installation Tips

Match the 50Ω series cables exactly with the preamplifier, do not mix with 75Ω or 300Ω accessories

Install the probe perpendicularly to the metal end face, set the reference gap within a reasonable range

Do not cut or bend the cable, keep away from power lines to avoid electromagnetic interference

The shielding layer should be uniformly grounded at one end on the control cabinet side
