Setting the Sensor
The sensor has been designed so that for the greatest measurement range the sensor head should be
positioned mid-way through its travel, i.e. 3mm (118mil) in real terms, out of a possible 6mm (236mil). The
ideal displacement is 0.00mm (0mil) however anywhere between ±0.2mm (±8mil) can be used as a start
point. In order to fit the sensor the following needs to done:
•
Loosen the clamp knob counter-clockwise so that the clamp is as flat as possible.
•
Fit the sensor into the chosen empty brush box or sleeve along with any required packing pieces (or
custom made holder) but do not tighten fully at this stage. Care should be taken to ensure that the sensor
is fitted as square as possible in the brush box and if a commutator is being profiled (ideally) in the centre
of a bar not in the gap between bars.
•
The sensor must be located in the brush box so the display reads ±0.2mm or ±8 mil or less; this will be
highlighted by the screen displaying either red, amber or green icons
