Perform a Time Base Calibration
As soon as the calibration function triggers, the
current measurement is interrupted and a gauge
displays on the LCD. The gauge simply indicates
calibration action rather than calibration course, as
the calibration time is unpredictable. When the
calibration is finished, a calibration result will
display on LCD, and the interrupted measurement
will restart.

NOTE
Time base calibration can be taken during a short time only
when the inner temperature is stable. When the inner
temperature is rising up, calibration operation will bring a
long-time course or a failure. If the input reference signal is
abnormal, it will take a long and unpredictable time to exit,
and error shows on the screen.
