6.8 Calibrating DC Voltage
Offset Correction for DC Voltage
To carry out the Offset Correction for DC Voltage measurements, a short-circuit must
be applied to the V-
Ω
front input connectors (Accessory No. 3016).
After triggering a zero-point correction by pressing the zero key, an Offset
Measurement is carried out for the currently set measurement range.
Notice
:
If calibration is done with a calibrator, the calibrator's offset has to be
corrected for at the 5017 front input correction. The cables must be
properly connected between calibrator and 5017 and the calibrator set to
Zero, prior to the Offset correction of the 5017. Now perform the 5017
offset correction by pressing the zero key on the front panel.
Important:
After calibration is completed and the calibrator removed, another offset
correction must be performed , with a short-circuit, at the 5017 front input
connector as described above.
Calibration of DC Voltage
After selecting the desired measurement range, an exactly known positive or negative
reference voltage source is connected to the input connectors. The voltage can be
between 5% and 100% (preferably between 20% and 100%) of the display range for the
measurement range in question.
If the input voltage is not in this range, an error message is displayed.
The 5017 will now display a value that should correspond to the value of the known
voltage source. If the reference value deviates too much from the measured value, the
measurement range must be recalibrated.
If several measurement ranges are to be calibrated, the process described above is
started again for the next range.
