Calibration
Primary Training
On current inputs, terminals type RTK/S are provided with short-circuit bridges to
short out the field inputs. The operator must therefore move the bridge to short out
the field inputs, and screw it very tightly, before having access to the sliding switches
of the terminals; the switches may then be opened to disconnect the input circuit from
field wiring.
After calibration, remove the reference current source, close the sliding switches of
the terminal, tighten them firmly, then unlock the short-circuit bridge.
