GOSSEN-METRAWATT GMBH 13
Operation
Setting of values with the rotary knob
– Slight turning does not change the value to be set at first (medium range of the rotating angle) to avoid an accidental change.
– When turning stronger to the left or right against the spring tension, the value is decremented or incremented for coarse setting the faster the knob
is turned further (spring range).
– When the rotary knob is released, the spring range is left.
– After a change of the value in the spring range, vernier setting by approximately 5 digits is possible on the medium range.
– The value is stored and effective after 2.5 s or after a key stroke. This is signalled by a brief blanking of the display.
