jb recommend JBR-3296 series replace Bourns’3296 Presets and Trimmer for calibration

JBR-3296 preset or trimmer potentiometers are small “set-and-forget” type potentiometers that allow for very fine or occasional adjustments to be easily made to a circuit.

Rotary preset potentiometers are miniature versions of the standard variable resistor designed to be mounting directly on a printed circuit board and are adjusted by means of a small bladed screwdriver or similar plastic tool.

JBR-3296 series rotary potentiometer normally offers less than 300 degrees of angular movement from minimum to maximum resistance.
