The CAL REFL OPEN softkey starts the open-circuit calibration. During
calibration the following message is displayed:
IEC/IEEE-bus command
CORR:COLL OPEN
The CAL REFL SHORT softkey starts the short-circuit calibration.
If both calibrations (open circuit, short circuit) are carried out, the calibration
curve is formed by averaging the two measurements and stored in the
memory. The order of measurements is optional.
After the calibration the following message is displayed:
The display is cleared after approx. 3 seconds.
