Continuing with
three- to five-point
calibration
14. Start the measurement with <ENTER> .
The measured value is checked for stability (stability control). The [AR]
status indicator is displayed. A progress bar is displayed and the display
of the measured parameter flashes.
15. Wait for the measurement with stability control to be completed or ter-
minate the stability control and take over the calibration value with
<ENTER> .
The calibration display for the next buffer appears (voltage display).
16. If necessary, finish the calibration procedure as a two-point calibration
with <M> .
The calibration record is displayed.
