Testing Process:
We start by doing a detailed physical inspection under light magnification to asses the cantilever condition, its position in the cartridge body, and the condition of the suspension.

We also inspect any coil wires and the output connections to make sure it hasn't been strained. We then perform a light cleaning with specialized agents and very carefully blow dry with compressed air.

Following that, we conduct a thorough examination using our Wild Heerbrugg professional microscope. From there we can asses the wear and quality of the stylus and determine how much use it has seen, and if there are any mechanical issues. We can also identify if it needs further cleaning or care.

We then move the cartridge to a digital microscope where we take photos of the cantilever and stylus for future reference.

Next we move to the test bench where we can check for continuity of each channel and resistance.

On certain cartridges (or if the technician feels necessary) we install the cartridge on a turntable and run several test records to ascertain tacking ability, distortion, and compliance.
