MU-A-RectiRail DL2-rev01a-Gb 8 / 44
3.3 Magnets and electric stops
Magnets are used to hold the RectiRail DL2 in place. Once the rule has been
positioned on the area to be measured, press the two buttons securing the magnets
placed on the top of each insulating block.
These magnets ensure that the rule is held properly on the rail, thus contributing to
good contact between the rail and the electric stops. Measurement quality also
depends on the quality of this contact.
Moreover, these electric stops are made of hardened steel and have an aggressive
shape. They can be used to rub the rail should it exhibit an excessively thick rust layer.
Caution: as the two electric stops are interconnected, do not take measurements
on rail joints which have different voltages.
To make it easier to separate the magnets from the rail, slant the rule backwards, away
from yourself.
