Fig.29: Calibration menu for offset values and for amplitude values
Using this sub menu the calibration setup points ‘min’, ‘max’ and ‘free’ can be
selected. With items ‘min’ / ‘max’ the minimal / maximal adjustable offset and
amplitude value can be calibrated.
The following procedure is recommended:
- connect a voltage meter to the output connector OUTPUT of the instrument
- select the operating point to be calibrated ('min' or 'max' for offset or
amplitude calibration menu)
- adjust the value of the voltage meter to the exact value displayed by the
instrument (e.g., +5V for calibration of the max. offset) using the rotary
knob
- press button 2 (ENTER)
Now the new calibration value gets permanent.
Use the same procedure for calibration of min. offset and for max. and min.
amplitude.
Furthermore, parameter ‘free’ gives an additional set-point of the calibration
curve:
