Perform a Time Base Calibration
When the calibration function is triggered, the
current measurement is interrupted and a gauge
displays on the LCD. The gauge indicates
calibration action rather than calibration course, as
the calibration time is unpredictable. When the
calibration is finished, the LCD displays a
calibration, and the interrupted measurement
restarts.
Key Access: [SYS] > {More} > {Calibration}
NOTE
Time base calibration takes only a short time when the inner
temperature is stable. When the inner temperature is
increasing, calibration may take a long-time or will fail. If the
input reference signal is abnormal, the calibration cycle will
take a long and unpredictable time to exit, and the LCD will
display an error message.
