Setting relative deviation
All function modes of the calibrator except frequency mode allow a relative deviation of output value from the
main data to be set using a separate display. Relative deviation is displayed in the “minor data” section of the
display and is designated with „
%= 00.0000 % “ symbol. The relative deviation can be entered using one of
the methods described above, e.g. using the numeric keyboard, cursor keys or the potentiometer.

ENTER on the numeric keyboard
•
the auxiliary line below the main data on the display displays the total value of output signal
including the unit of measurement
•
the value of the signal at output terminals is: the value indicated by the main d ∆ %.
Maximum relative deviation which can be entered is
30.000 %.
The deviation can be positive or negative. If negative deviation is desired, press the display button l/-. If
positive deviation is then desired, press “ +/- “ button again. The polarity of the relative deviation can be
reversed using the cursor buttons or the potentiometer as well.
