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.
Setting relative deviation using numeric keyboard
• keep pressing the center cursor button until [ _ _ _ _ _ _ _ ] symbols appear under the relative
deviation value in the “minor data” section of the display
• enter the desired deviation and confirm the value by pressing “ % “ display button or by pressing
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 display + ∆ %.
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 labeled +/-. 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.
Setting relative deviation using cursor keys
• keep pressing the center cursor button until [ _ _ _ _ _ _ _ ] symbols appear under the relative
deviation value
• press <, >, ∧ or ∨ button. The display now includes cursor marks which point to the active digit
• ∧ and ∨ buttons can be used to change the active digit. <, > buttons can be used to change the
position of the cursor marks
• to get to the default screen, keep pressing the center cursor button until there is no [ _ _ _ _ _ _ _ ]
under any value, or press EXIT button. All values can be set using the buttons or the potentiometer..
