Calibration
Prevention of improper standard unit connection
To avoid improper connection of the three types of standard units (open/short/load), judgment can
be made by setting the limit with DC measurement.
During calibration measurement, if the limit values are set, exceeding the limit will result in an error,
and the calibration measurement will be stopped.
In case of an error, check that an appropriate standard unit is connected.
If the standard unit having a coaxial structure like the calibration kit is to be connected, connect
the standard unit by rotating the connector nut of the standard unit. The standard unit and the
central conductor of the connector will get damaged if the standard unit itself is rotated and
connected.
