WARNING: Need corr meas
When the OPEN correction, SHORT correction or LOAD correction is ON, this is
displayed when you change the setup of the cable length or measurement
frequency shift (1 MHz). In this case, the OPEN correction, SHORT correction
and LOAD correction are automatically turned OFF.
WARNING: Need load meas
This is displayed when you turn ON the LOAD correction from the front panel
although the setups of the cable length and measurement frequency shift (1
MHz) differ from those when measuring/setting up the LOAD correction data.
In this case, the LOAD correction is turned ON, but you need to measure the
LOAD correction data again for accurate measurement.
WARNING: Need open meas
This is displayed when you turn ON the OPEN correction from the front panel
although the setups of the cable length and measurement frequency shift (1
MHz) differ from those when measuring/setting up the OPEN correction data.
In this case, the OPEN correction is turned ON, but you need to measure the
OPEN correction data again for accurate measurement.
WARNING: Need short meas
This is displayed when you turn ON the SHORT correction from the front panel
although the setups of the cable length and measurement frequency shift (1
MHz) differ from those when measuring/setting up the SHORT correction data.
In this case, the SHORT correction is turned ON, but you need to measure the
SHORT correction data again for accurate measurement.
