Load transducer with 60 N.
Use S21 to select appropriate interval as given in Tab. 4.1 (page 16) (switch
on 4 + 7), and use P22 to adjust the output voltage to 10 V exactly. The mea-
suring range can also be adjusted with no transducer connected by means of
a calibration unit (e.g. K 3607) that simulates the transducer signal.
• Additive calibration signal
The measuring range can also be adjusted using the additive calibration sig-
nal (0.2 mV/V).

• 2mVńV + 1.2 mVńV
Calculate nominal measurement value, execute zero balance (see above) and
use S21 to select the corresponding measuring-range interval. Connect addi-
tive calibration signal (set S25 to CAL) and use P22 to adjust with the trans-
ducer under no load. The amplifier has now been calibrated. Adjust S25 to
MEAS.
